The following code example explains how to create a new Word document with few lines of code

//Creates an instance of WordDocument Instance (Empty Word Document)
WordDocument document = new WordDocument();
//Add a section & a paragraph in the empty document
document.EnsureMinimal();
//Append text to the last paragraph of the document
document.LastParagraph.AppendText("Hello World");
//Save and close the Word document
document.Save("Result.docx");
document.Close();
'Creates an instance of WordDocument Instance (Empty Word Document)

Creating a new Word document from scratch with basic elements

An entire Word document is represented by an instance of WordDocument and it is root element of DocIO’s DOM. Word document contains a collection of sections. A Word document must contain at least one section.

A section represents group of paragraphs, tables etc., that have a specific set of properties used to define the pages, number of columns, headers and footers and so on that decides how the text appears. A section should contain at least one paragraph in this body.

The following code example explains how to add a section into a WordDocument instance.

//Creates an instance of WordDocument Instance (Empty Word Document)
WordDocument document = new WordDocument();
//Adds a new section into the Word document
IWSection section = document.AddSection();
//Specifies the page margins 
section.PageSetup.Margins.All = 50f;
'Creates an instance of WordDocument Instance (Empty Word Document)
Dim document As New WordDocument()
'Adds a new section into the Word document
Dim section As IWSection = document.AddSection()
'Specifies the page margins
section.PageSetup.Margins.All = 50.0F
//Creates an instance of WordDocument Instance (Empty Word Document)
WordDocument document = new WordDocument();
//Adds a new section into the Word document
IWSection section = document.AddSection();
//Specifies the page margins 
section.PageSetup.Margins.All = 50f;
//Creates an instance of WordDocument Instance (Empty Word Document)
WordDocument document = new WordDocument();
//Adds a new section into the Word document
IWSection section = document.AddSection();
//Specifies the page margins 
section.PageSetup.Margins.All = 50f;
//Creates an instance of WordDocument Instance (Empty Word Document)
WordDocument document = new WordDocument();
//Adds a new section into the Word document
IWSection section = document.AddSection();
//Specifies the page margins 
section.PageSetup.Margins.All = 50f;

All the textual contents in a Word document is represented by Paragraphs. Within the paragraph, textual contents are grouped into one or more child elements such as TextRange, field etc. Each TextRange represents a region of text with a common set of rich text formatting.

The following code example explains how to add a Paragraph into a Word document

//Adds a new simple paragraph into the section
IWParagraph firstParagraph = section.AddParagraph();
//Sets the paragraph's horizontal alignment as justify
firstParagraph.ParagraphFormat.HorizontalAlignment = HorizontalAlignment.Justify;
//Adds a text range into the paragraph
IWTextRange firstTextRange = firstParagraph.AppendText("AdventureWorks Cycles,");
//sets the font formatting of the text range
firstTextRange.CharacterFormat.Bold = true;
firstTextRange.CharacterFormat.FontName = "Calibri";
firstTextRange.CharacterFormat.FontSize = 14;
//Adds another text range into the paragraph
IWTextRange secondTextRange = firstParagraph.AppendText(" the fictitious company on which the AdventureWorks sample databases are based, is a large, multinational manufacturing company.");
//sets the font formatting of the text range
secondTextRange.CharacterFormat.FontName = "Calibri";
secondTextRange.CharacterFormat.FontSize = 11;
'Adds a new simple paragraph into the section
Dim firstParagraph As IWParagraph = section.AddParagraph()
'Sets the paragraph's horizontal alignment as justify
firstParagraph.ParagraphFormat.HorizontalAlignment = HorizontalAlignment.Justify
'Adds a text range into the paragraph
Dim firstTextRange As IWTextRange = firstParagraph.AppendText("AdventureWorks Cycles, ")
'sets the font formatting of the text range
firstTextRange.CharacterFormat.Bold = True
firstTextRange.CharacterFormat.FontName = "Calibri"
firstTextRange.CharacterFormat.FontSize = 14
'Adds another text range into the paragraph
Dim secondTextRange As IWTextRange = firstParagraph.AppendText("the fictitious company on which the AdventureWorks sample databases are based, is a large, multinational manufacturing company.")
'sets the font formatting of the text range
secondTextRange.CharacterFormat.FontName = "Calibri"
secondTextRange.CharacterFormat.FontSize = 11
//Adds a new simple paragraph into the section
IWParagraph firstParagraph = section.AddParagraph();
//Sets the paragraph's horizontal alignment as justify
firstParagraph.ParagraphFormat.HorizontalAlignment = Syncfusion.DocIO.DLS.HorizontalAlignment.Justify;
//Adds a text range into the paragraph
IWTextRange firstTextRange = firstParagraph.AppendText("AdventureWorks Cycles,");
//sets the font formatting of the text range
firstTextRange.CharacterFormat.Bold = true;
firstTextRange.CharacterFormat.FontName = "Calibri";
firstTextRange.CharacterFormat.FontSize = 14;
//Adds another text range into the paragraph
IWTextRange secondTextRange = firstParagraph.AppendText(" the fictitious company on which the AdventureWorks sample databases are based, is a large, multinational manufacturing company.");
//sets the font formatting of the text range
secondTextRange.CharacterFormat.FontName = "Calibri";
secondTextRange.CharacterFormat.FontSize = 11;
//Adds a new simple paragraph into the section
IWParagraph firstParagraph = section.AddParagraph();
//Sets the paragraph's horizontal alignment as justify
firstParagraph.ParagraphFormat.HorizontalAlignment = Syncfusion.DocIO.DLS.HorizontalAlignment.Justify;
//Adds a text range into the paragraph
IWTextRange firstTextRange = firstParagraph.AppendText("AdventureWorks Cycles,");
//sets the font formatting of the text range
firstTextRange.CharacterFormat.Bold = true;
firstTextRange.CharacterFormat.FontName = "Calibri";
firstTextRange.CharacterFormat.FontSize = 14;
//Adds another text range into the paragraph
IWTextRange secondTextRange = firstParagraph.AppendText(" the fictitious company on which the AdventureWorks sample databases are based, is a large, multinational manufacturing company.");
//sets the font formatting of the text range
secondTextRange.CharacterFormat.FontName = "Calibri";
secondTextRange.CharacterFormat.FontSize = 11;
//Adds a new simple paragraph into the section
IWParagraph firstParagraph = section.AddParagraph();
//Sets the paragraph's horizontal alignment as justify
firstParagraph.ParagraphFormat.HorizontalAlignment = Syncfusion.DocIO.DLS.HorizontalAlignment.Justify;
//Adds a text range into the paragraph
IWTextRange firstTextRange = firstParagraph.AppendText("AdventureWorks Cycles,");
//sets the font formatting of the text range
firstTextRange.CharacterFormat.Bold = true;
firstTextRange.CharacterFormat.FontName = "Calibri";
firstTextRange.CharacterFormat.FontSize = 14;
//Adds another text range into the paragraph
IWTextRange secondTextRange = firstParagraph.AppendText(" the fictitious company on which the AdventureWorks sample databases are based, is a large, multinational manufacturing company.");
//sets the font formatting of the text range
secondTextRange.CharacterFormat.FontName = "Calibri";
secondTextRange.CharacterFormat.FontSize = 11;

The following code example shows how to add an image into the Word document.

//Adds another paragraph and aligns it as center
IWParagraph paragraph = section.AddParagraph();
paragraph.ParagraphFormat.HorizontalAlignment = HorizontalAlignment.Center;
//Adds a picture into the paragraph
IWPicture picture = paragraph.AppendPicture(Image.FromFile("DummyProfilePicture.jpg"));
//Specify the size of the picture
picture.Height = 100;
picture.Width = 100;
'Adds another paragraph and aligns it as center
Dim paragraph As IWParagraph = section.AddParagraph()
paragraph.ParagraphFormat.HorizontalAlignment = HorizontalAlignment.Center
'Adds a picture into the paragraph
Dim picture As IWPicture = paragraph.AppendPicture(Image.FromFile("DummyProfilePicture.jpg"))
'Specifies the size of the picture
picture.Height = 100
picture.Width = 100
//Adds another paragraph and aligns it as center
IWParagraph paragraph = section.AddParagraph();
paragraph.ParagraphFormat.HorizontalAlignment = Syncfusion.DocIO.DLS.HorizontalAlignment.Center;
//Adds a picture into the paragraph
//"App" is the class of Portable project.
Assembly assembly = typeof(App).GetTypeInfo().Assembly;
Stream imageStream1 = assembly.GetManifestResourceStream("CreateWordSample.Assets.DummyProfilePicture.jpg");
IWPicture picture = paragraph.AppendPicture(imageStream1);
//Specify the size of the picture
picture.Height = 100;
picture.Width = 100;
//Adds another paragraph and aligns it as center
IWParagraph paragraph = section.AddParagraph();
paragraph.ParagraphFormat.HorizontalAlignment = Syncfusion.DocIO.DLS.HorizontalAlignment.Center;
//Adds a picture into the paragraph
FileStream image1 = new FileStream("DummyProfilePicture.jpg", FileMode.Open, FileAccess.Read);
IWPicture picture = paragraph.AppendPicture(image1);
//Specify the size of the picture
picture.Height = 100;
picture.Width = 100;
//Adds another paragraph and aligns it as center
IWParagraph paragraph = section.AddParagraph();
paragraph.ParagraphFormat.HorizontalAlignment = Syncfusion.DocIO.DLS.HorizontalAlignment.Center;
//Adds a picture into the paragraph
//"App" is the class of Portable project.
Assembly assembly = typeof(App).GetTypeInfo().Assembly;
Stream imageStream1 = assembly.GetManifestResourceStream("CreateWordSample.Assets.DummyProfilePicture.jpg");
IWPicture picture = paragraph.AppendPicture(imageStream1);
//Specify the size of the picture
picture.Height = 100;
picture.Width = 100;

Table is another important element in Word that contains a set of paragraphs arranged in rows and columns. You can create simple as well as complex table by using Essential DocIO’s API. The following code example creates a simple table and adds contents into it. Each table cell must contain at least one paragraph.

//Adds a table into the Word document
IWTable table = section.AddTable();
//Creates the specified number of rows and columns
table.ResetCells(2,2);
//Accesses the instance of the cell (first row, first cell)
WTableCell firstCell = table.Rows[0].Cells[0];
//Specifies the width of the cell
firstCell.Width = 150;
//Adds a paragraph into the cell; a cell must have atleast 1 paragraph
paragraph = firstCell.AddParagraph();
IWTextRange textRange = paragraph.AppendText("Profile picture");
textRange.CharacterFormat.Bold = true;
//Accesses the instance of cell (first row, second cell)
WTableCell secondCell = table.Rows[0].Cells[1];
secondCell.Width = 330;
paragraph = secondCell.AddParagraph();
textRange = paragraph.AppendText("Description");
textRange.CharacterFormat.Bold = true;
firstCell = table.Rows[1].Cells[0];
firstCell.Width = 150;
paragraph = firstCell.AddParagraph();
IWPicture profilePicture = paragraph.AppendPicture(Image.FromFile(DummyProfile-Picture.jpg"));
profilePicture.Height = 100;
profilePicture.Width = 100;
secondCell = table.Rows[1].Cells[1];
secondCell.Width = 330;
paragraph = secondCell.AddParagraph();
textRange = paragraph.AppendText("AdventureWorks Cycles, the fictitious company on which the AdventureWorks sample databases are based, is a large, multinational manufacturing company.");

Finally, save the document in file system and close its instance.

//Saves the document in the given name and format
document.Save(outputFileName, FormatType.Docx);
//Releases the resources occupied by WordDocument instance
document.Close();
'Saves the document in the given name and format
document.Save(outputFileName, FormatType.Docx)
'Releases the resources occupied by WordDocument instance
document.Close()
MemoryStream stream = new MemoryStream();
//Saves the Word document to MemoryStream
await document.SaveAsync(stream, FormatType.Docx);
document.Close();
//Saves the stream as Word document file in local machine
Save(stream, outputFileName);
//Please refer the below link to save Word document in UWP platform
//https://help.syncfusion.com/file-formats/docio/create-word-document-in-uwp#save-word-document-in-uwp
MemoryStream stream = new MemoryStream();
//Saves the Word document to  MemoryStream
document.Save(stream, FormatType.Docx);
document.Close();
stream.Position = 0;
//Download Word document in the browser
return File(stream, "application/msword", outputFileName);
MemoryStream stream = new MemoryStream();
//Saves the Word document to MemoryStream

The resultant Word document looks as follows.

Creating a new Word document from scratch with basic elements

Modifying an existing Word document

Essential DocIO allows you to manipulate an existing Word document, RTF, WordML, HTML and Plain text files. You can modify the documents either by manipulating DocIO’s DOM or by using DocIO’s built-in functionalities such as Find and Replace, replacing bookmark contents etc.

Here, you can see how an existing Word document is loaded into DocIO’s DOM, replaces an existing content with another and finally saves the Word document.

You can open an existing Word document either by using constructor of WordDocument class or by using Open method of WordDocument class that reads the document and populates DocIO’s DOM. The following code example shows how to load an existing document.

//Loads an existing Word document into DocIO instance
WordDocument document = new WordDocument("Giant Panda.docx");
//Replaces the word "bear" as "panda"
document.Replace("bear", "panda", false, true);
//Saves the Word document
document.Save("Result.docx");
//Closes the document
document.Close();
'Loads an existing Word document into DocIO instance
Dim document As New WordDocument("Giant Panda.docx")
'Replaces the word "bear" as "panda"
document.Replace("bear", "panda", False, True)
'Saves the Word document
document.Save("Result.docx")

Performing Mail merge

Essential DocIO allows to generate documents by filling data in template document from data source. Mail merge operation automatically maps the column name in the data source and names of the merge fields in the template Word document and fills the data.

The following data sources are supported by Essential DocIO for performing Mail merge.

  • String Arrays
  • ADO.NET objects
  • Business Objects
  • Dynamic objects

Also, you can perform more than one Mail merge operations over the same template to generate document as per your requirement.

Follow the given steps to perform simple Mail merge in a Word document.

Let’s consider that you have a template Word document with merge fields as shown.

Performing Mail merge input document

The MailMerge class provides various overloads for Execute method to perform Mail merge from various data source. The Mail merge operation replaces the matching merge fields with the respective data.

The following code example shows how to perform simple Mail merge by using string array.

//Loads the template document with required merge fields
WordDocument document = new WordDocument(@"..\..\data\SimpleMailMergeTemplate.docx");
//Initializes the string array with field names
string[] fieldNames = new string[] {"FirstName", "LastName", "Email", "Country"};
//Initializes the string array with field values
string[] fieldValues = new string[] {"John", "Smith", "john_smith@domain.com", "USA"};
//Executes the mail merge operation that replaces the matching field names with field values respectively.
document.MailMerge.Execute(fieldNames, fieldValues);
//Saves and closes the WordDocument instance
document.Save("result.docx");
document.Close();
'Loads the template document with required merge fields
Dim document As New WordDocument("..\..\data\SimpleMailMergeTemplate.docx")
'Initializes the string array with field names
Dim fieldNames As String() = New String() {"FirstName", "LastName", "Email", "Country"}
'Initializes the string array with field values
Dim fieldValues As String() = New String() {"John", "Smith", "john_smith@domain.com", "USA"}
'Executes the mail merge operation that replaces the matching field names with field values respectively.
document.MailMerge.Execute(fieldNames, fieldValues)
'Saves and closes the WordDocument instance
document.Save("result.docx")
document.Close()
Assembly assembly = typeof(App).GetTypeInfo().Assembly;
Stream FileStream = assembly.GetManifestResourceStream("CreateWordSample.Assets.SimpleMailMergeTemplate.docx");
//Loads an existing Word document into DocIO instance
WordDocument document = new WordDocument(FileStream);
//Initializes the string array with field names
string[] fieldNames = new string[] { "FirstName", "LastName", "Email", "Country" };
//Initializes the string array with field values
string[] fieldValues = new string[] { "John", "Smith", "john_smith@domain.com", "USA" };
//Executes the mail merge operation that replaces the matching field names with field values respectively.
document.MailMerge.Execute(fieldNames, fieldValues);
MemoryStream stream = new MemoryStream();
//Saves the Word document to MemoryStream
await document.SaveAsync(stream, FormatType.Docx);
document.Close();
//Saves the stream as Word document file in local machine
Save(stream, "Result.docx");
//Please refer the below link to save Word document in UWP platform
//https://help.syncfusion.com/file-formats/docio/create-word-document-in-uwp#save-word-document-in-uwp
FileStream fileStream = new FileStream(@"SimpleMailMergeTemplate.docx", FileMode.Open,FileAccess.ReadWrite);
//Loads an existing Word document into DocIO instance
WordDocument document = new WordDocument(fileStream, FormatType.Automatic);
//Initializes the string array with field names
string[] fieldNames = new string[] { "FirstName", "LastName", "Email", "Country" };
//Initializes the string array with field values
string[] fieldValues = new string[] { "John", "Smith", "john_smith@domain.com", "USA" };
//Executes the mail merge operation that replaces the matching field names with field values respectively.
document.MailMerge.Execute(fieldNames, fieldValues);
MemoryStream stream = new MemoryStream();
//Saves the Word document to  MemoryStream
document.Save(stream, FormatType.Docx);
stream.Position = 0;
document.Close();
//Download Word document in the browser
return File(stream, "application/msword", "Result.docx");
Assembly assembly = typeof(App).GetTypeInfo().Assembly;
Stream FileStream = assembly.GetManifestResourceStream("CreateWordSample.Assets.SimpleMailMergeTemplate.docx");
//Loads an existing Word document into DocIO instance
WordDocument document = new WordDocument(FileStream,FormatType.Automatic);
//Initializes the string array with field names
string[] fieldNames = new string[] { "FirstName", "LastName", "Email", "Country" };
//Initializes the string array with field values
string[] fieldValues = new string[] { "John", "Smith", "john_smith@domain.com", "USA" };
//Executes the mail merge operation that replaces the matching field names with field values respectively.
document.MailMerge.Execute(fieldNames, fieldValues);
//Saves the Word document to MemoryStream
MemoryStream stream = new MemoryStream();
document.Save(stream, FormatType.Docx);
document.Close();
//Save the stream as a file in the device and invoke it for viewing
Xamarin.Forms.DependencyService.Get<ISave>().SaveAndView("GettingStartedSample.docx", "application/msword", stream);

The resultant Word document look as follows.

Performing Mail merge output document

Simple Mail merge with Group

You can perform Mail merge with group to append multiple records from data source into a single document. Group is a part of the document enclosed by two special merge fields named «TableStart:TableName» and «TableEnd:TableName»

  • «TableStart:TableName» - denotes the start of the group
  • «TableEnd:TableName» - denotes the end of the group

The region between these two merge fields get repeated for every record from the data source.

For example – let’s consider that you have a template document as shown.

Simple Mail merge with Group input document

Here, in this template, Employees is the group name and exact same name should be used while performing Mail merge through code. There are two special merge fields “TableStart:Employees” and “TableEnd:Employees”, to denote the start and end of the Mail merge group.

To merge an image in the replace of a merge field, you need to add a prefix (“Image:”)the merge field name.

For example: the merge field name should be like “«Image:Photo»”(«Image:MergeFieldName»)

The following code example shows how to perform Mail merge with objects.

//Loads the template document
WordDocument document = new WordDocument(@"..\..\Data\EmployeesTemplate.doc");
//Gets the employee details as IEnumerable collection
List<Employee> employeeList = GetEmployees();
//Creates an instance of MailMergeDataTable by specifying MailMerge group name and IEnumerable collection
MailMergeDataTable dataSource = new MailMergeDataTable("Employees", employeeList);
//Performs Mail merge
document.MailMerge.ExecuteGroup(dataSource);
//Saves and closes the document
document.Save("Result.docx");
document.Close();
//Loads the template document
Dim document As New WordDocument("..\..\Data\EmployeesTemplate.doc")
'Gets the employee details as IEnumerable collection
Dim employeeList As List(Of Employee) = GetEmployees()
'Creates an instance of MailMergeDataTable by specifying MailMerge group name and IEnumerable collection

The following code example illustrates how to convert a Word document into PDF document.

//Loads the template document
WordDocument wordDocument = new WordDocument(inputWordDocument, FormatType.Automatic );
//Initializes chart to image converter for converting charts during Word to pdf conversion
wordDocument.ChartToImageConverter = new ChartToImageConverter();
wordDocument.ChartToImageConverter.ScalingMode = ScalingMode.Normal;
//Creates an instance of DocToPDFConverter - responsible for Word to PDF conversion
DocToPDFConverter converter = new DocToPDFConverter();
//Converts Word document into PDF document
PdfDocument pdfDocument = converter.ConvertToPDF(wordDocument);
//Saves the PDF file to file system
pdfDocument.Save("Sample.pdf");
//closes the instance of document objects
pdfDocument.Close();
wordDocument.Close();
'Loads the template document 
Dim wordDocument As New WordDocument(inputWordDocument, FormatType.Automatic)
'Initializes chart to image converter for converting charts during Word to pdf conversion
wordDocument.ChartToImageConverter = New ChartToImageConverter()
wordDocument.ChartToImageConverter.ScalingMode = ScalingMode.Normal
'Creates an instance of DocToPDFConverter - responsible for Word to PDF conversion
Dim converter As New DocToPDFConverter()
'Converts Word document into PDF document
Dim pdfDocument As PdfDocument = converter.ConvertToPDF(wordDocument)
'Saves the PDF file to file system
pdfDocument.Save("Sample.pdf")
'closes the instance of document objects
pdfDocument.Close()
wordDocument.Close()
Assembly assembly = typeof(App).GetTypeInfo().Assembly;
Stream inputWordDocument = assembly.GetManifestResourceStream("CreateWordSample.Assets.WordToPDF.docx");
//Loads the template document
WordDocument wordDocument = new WordDocument(inputWordDocument, FormatType.Automatic);
//Creates an instance of DocToPDFConverter - responsible for Word to PDF conversion
DocIORenderer converter = new DocIORenderer();
//Converts Word document into PDF document
PdfDocument pdfDocument = converter.ConvertToPDF(wordDocument);
//Save the document into stream.

pdfDocument.Save(outputStream);
//Closes the instance of PDF document object

NOTE

When the ChartToImageConverter object is not initialized, then the charts in Word document gets skipped during Word to PDF conversion.
ChartToImageConverter is supported from .NET Framework 4.0 onwards
