This section covers the various formatting options in a cell or a range.
Create a Style
The following code shows how to create and apply cell style.
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);
IWorksheet worksheet = workbook.Worksheets[0];
//Creating a new style with cell back color, fill pattern and font attribute
IStyle style = workbook.Styles.Add("NewStyle");
style.Color = Color.LightGreen;
style.FillPattern = ExcelPattern.DarkUpwardDiagonal;
style.Font.Bold = true;
worksheet.Range["B2"].CellStyle = style;
//Saving the workbook as stream
FileStream stream = new FileStream("Style.xlsx", FileMode.Create, FileAccess.ReadWrite);
workbook.SaveAs(stream);
stream.Dispose();
}using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);
IWorksheet worksheet = workbook.Worksheets[0];
//Creating a new style with cell back color, fill pattern and font attribute
IStyle style = workbook.Styles.Add("NewStyle");
style.Color = Color.LightGreen;
style.FillPattern = ExcelPattern.DarkUpwardDiagonal;
style.Font.Bold = true;
worksheet.Range["B2"].CellStyle = style;
workbook.SaveAs("Style.xlsx");
}Using excelEngine As ExcelEngine = New ExcelEngine()
Dim application As IApplication = excelEngine.Excel
application.DefaultVersion = ExcelVersion.Excel2013
Dim workbook As IWorkbook = application.Workbooks.Create(1)
Dim worksheet As IWorksheet = workbook.Worksheets(0)
'Creating a new style with cell back color, fill pattern and font attribute
Dim style As IStyle = workbook.Styles.Add("NewStyle")
style.Color = Color.LightGreen
style.FillPattern = ExcelPattern.DarkUpwardDiagonal
style.Font.Bold = True
worksheet.Range("B2").CellStyle = style
workbook.SaveAs("Style.xlsx")
End UsingA complete working example to create style in C# is present on this GitHub page.
Set Default Style for row or column
It is the recommended and optimized approach to format entire row or column with same styles instead of formatting each and every cell individually. Use the following code to set default style.
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);
IWorksheet worksheet = workbook.Worksheets[0];
//Define new styles to apply in rows and columns
IStyle rowStyle = workbook.Styles.Add("RowStyle");
rowStyle.Color = Color.LightGreen;
IStyle columnStyle = workbook.Styles.Add("ColumnStyle");
columnStyle.Color = Color.Orange;
//Set default row style for entire row
worksheet.SetDefaultRowStyle(1, 2, rowStyle);
//Set default column style for entire column
worksheet.SetDefaultColumnStyle(1, 2, columnStyle);
//Saving the workbook as stream
FileStream stream = new FileStream("DefaultStyles.xlsx", FileMode.Create, FileAccess.ReadWrite);
workbook.SaveAs(stream);
stream.Dispose();
}using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);
IWorksheet worksheet = workbook.Worksheets[0];
//Define new styles to apply in rows and columns
IStyle rowStyle = workbook.Styles.Add("RowStyle");
rowStyle.Color = Color.LightGreen;
IStyle columnStyle = workbook.Styles.Add("ColumnStyle");
columnStyle.Color = Color.Orange;
//Set default row style for entire row
worksheet.SetDefaultRowStyle(1, 2, rowStyle);
//Set default column style for entire column
worksheet.SetDefaultColumnStyle(1, 2, columnStyle);
workbook.SaveAs("DefaultStyles.xlsx");
}Using excelEngine As ExcelEngine = New ExcelEngine()
Dim application As IApplication = excelEngine.Excel
application.DefaultVersion = ExcelVersion.Excel2013
Dim workbook As IWorkbook = application.Workbooks.Create(1)
Dim worksheet As IWorksheet = workbook.Worksheets(0)
'Define new styles to apply in rows and columns
Dim rowStyle As IStyle = workbook.Styles.Add("RowStyle")
rowStyle.Color = Color.LightGreen
Dim columnStyle As IStyle = workbook.Styles.Add("ColumnStyle")
columnStyle.Color = Color.Orange
'Set default row style for entire row
worksheet.SetDefaultRowStyle(1, 2, rowStyle)
'Set default column style for entire column
worksheet.SetDefaultColumnStyle(1, 2, columnStyle)
workbook.SaveAs("DefaultStyles.xlsx")
End UsingA complete working example to apply default style for rows and columns in C# is present on this GitHub page.
NOTE
Applying custom styles will override original styles.
TIPS
To apply styles for whole column instead of applying in each cell, use default styles.
Apply Global Style
The XlsIO adds styles globally that can be applied to one or more cells in a workbook. This is a recommended approach to apply single style in different rows and columns, which improves memory and performance considerably.
To learn more about performance, refer to the Improving Performing section for better performance in XlsIO.
The following code snippet illustrates how to set header style and body style to the cells.
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;

Excel document with Global Styles
Apply Number Formats
Number Formats are codes that helps to control the appearance of cell values especially numbers in an Excel document. Excel recognizes the numbers in various formats like:
- Number
- Currency
- Percentage
- DateTime
- Accounting
- Scientific
- Fraction and
- Text
This number format can be of maximum 4 parts, separated by semicolons. They are:
- Positive Numbers
- Negative Numbers
- Zeros
- Text
Each part is an individual number format. Default format is “General”, it means anything that will fit.
The following table shows various custom formatting codes:
|
Number Code |
Description |
|---|---|
|
General |
General number format. |
|
0 (zero) |
Digit placeholder. This code pads the value with zeros to fill the format. |
|
# |
Digit placeholder. This code does not display extra zeros. |
|
? |
Digit placeholder. This code leaves a space for insignificant zeros but does not display them. |
|
. (period) |
Decimal placeholder. The decimal placeholder determines how many digits are displayed to the left and right of the decimal separator. |
|
% |
Percentage placeholder. Multiplies by 100 and adds the % character. |
|
, (comma) |
Thousands separator. A comma followed by a placeholder (0 or #) scales the number by a thousand. |
|
E+ E- e+ e- |
Scientific notation. |
|
Text Code |
Description |
|
$ - + / ( ) : space |
These characters are displayed in the number. To display any other character, enclose the character in quotation marks or precede it with a backslash. |
|
\character |
This code displays the succeeding character you specify. Note Typing !, ^, &, ', ~, {, }, =, <, or > automatically places a backslash in front of the character. |
|
"text" |
This code displays the text. |
|
* |
This code repeats the next character in the format to fill the column width. Note: Only one asterisk per section of a format is allowed. |
|
_ (underscore) |
This code skips the width of the next character. This code is commonly used as "_)" (without the quotation marks) to leave space for a closing parenthesis in a positive number format when the negative number format includes parentheses. This allows the values to line up at the decimal point. |
|
@ |
Text placeholder. |
|
Date Code |
Description |
|
m |
Month as a number without leading zeros (1-12). |
|
mm |
Month as a number with leading zeros (01-12). |
|
mmm |
Month as an abbreviation (Jan - Dec). |
|
mmmm |
Unabbreviated Month (January - December). |
|
d |
Day without leading zeros (1-31). |
|
dd |
Day with leading zeros (01-31). |
|
ddd |
Week day as an abbreviation (Sun - Sat). |
|
dddd |
Unabbreviated week day (Sunday - Saturday). |
|

|
AM/PM am/pm |
Time based on the twelve-hour clock. |
|
Miscellaneous Code |
Description |
|
[BLACK], [BLUE], [CYAN], [GREEN], [MAGENTA], [RED], [WHITE], [YELLOW], [COLOR n] |
These codes display the characters in the specified colors. Note: n is a value from 1 to 56 and refers to the nth color in the color palette. |
|
[Condition value] |
Condition may be <, >, =, >=, <=, <> and value may be any number. Note: A number format may contain up to two conditions. |

Access number format applied results at runtime
Cell values can be accessed as Text, Number, DateTime and Formula of IRange interface. In addition to this, there is an another property DisplayText in IRange, which returns a resultant value of a cell with its number format applied.
The following code example illustrates how to display the text of a cell.
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);
IWorksheet worksheet = workbook.Worksheets[0];
//Set value to the cell
worksheet.Range["C4"].Number = 1.20;
//Set value to a cell
worksheet.Range["B4"].Text = "$#,##0.00";
//Get display text of the cell
string text = worksheet.Range["B4"].DisplayText;
//Saving the workbook as stream
FileStream stream = new FileStream("Output.xlsx", FileMode.Create, FileAccess.ReadWrite);
workbook.SaveAs(stream);
stream.Dispose();
}using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);
IWorksheet worksheet = workbook.Worksheets[0];
//Set value to the cell

//Set value to a cell
worksheet.Range["B4"].Text = "$#,##0.00";
//Get display text of the cell
string text = worksheet.Range["B4"].DisplayText;
workbook.SaveAs("Output.xlsx");
}Using excelEngine As ExcelEngine = New ExcelEngine()
Dim application As IApplication = excelEngine.Excel
application.DefaultVersion = ExcelVersion.Excel2013

Apply Cell Text Alignment
The XlsIO supports the following alignment options:
- Horizontal Alignment
- Vertical Alignment
- Indentation
- Orientation
- Text Direction
Horizontal Alignment
This code snippet aligns the cell content horizontally.
//Text Alignment Setting (Horizontal Alignment)
worksheet.Range["A2"].CellStyle.HorizontalAlignment = ExcelHAlign.HAlignCenter;//Text Alignment Setting (Horizontal Alignment)
worksheet.Range["A2"].CellStyle.HorizontalAlignment = ExcelHAlign.HAlignCenter;'Text Alignment Setting (Horizontal Alignment)
worksheet.Range("A2").CellStyle.HorizontalAlignment = ExcelHAlign.HAlignCenterVertical Alignment
This code snippet aligns the cell content vertically.
//Text Alignment Setting (Vertical Alignment)
worksheet.Range["B2"].CellStyle.VerticalAlignment = ExcelVAlign.VAlignBottom;//Text Alignment Setting (Vertical Alignment)
worksheet.Range["B2"].CellStyle.VerticalAlignment = ExcelVAlign.VAlignBottom;'Text Alignment Setting (Vertical Alignment)
worksheet.Range("B2").CellStyle.VerticalAlignment = ExcelVAlign.VAlignBottomIndentation
This allows to set the cell content either to move it closer to the cell border or to move it farther away from cell border.
//Text Indent Setting
worksheet.Range["C6"].CellStyle.IndentLevel = 6;//Text Indent Setting
worksheet.Range["C6"].CellStyle.IndentLevel = 6;'Text Indent Setting
worksheet.Range("C6").CellStyle.IndentLevel = 6Orientation
This helps to rotate the cell text diagonally or vertically. The text orientation can be set by using the Rotation property as shown as follows.
//Text Orientation Settings
worksheet.Range["C2"].CellStyle.Rotation = 60;//Text Orientation Settings
worksheet.Range["C2"].CellStyle.Rotation = 60;'Text Orientation Settings
worksheet.Range("C2").CellStyle.Rotation = 60Text Direction
You can specify the text direction by using the ReadingOrder property as shown as follows.
//Text Direction Setting

HTML String Formatting
HTML string generates a string of characters with different formatting styles using different HTML tags for each character. This makes it easy to manipulate the text or value in the worksheet range as each character is independent and doesn’t depend on hierarchical tag structure.
XlsIO supports adding HTML Rich-Text to a range of cells in worksheet.
Applying HTML String
The following code snippet illustrates how to read and write HTML Rich-Text using HtmlString property of IRange.
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(3);
IWorksheet worksheet = workbook.Worksheets[0];
//Add HTML string
worksheet.Range["A1"].HtmlString = "<font style=\"color:red;font-family:Magneto;font-size:12px; \">Welcome Syncfusion</font>";
//Assign HTML string as text to different range
worksheet.Range["A2"].Text = worksheet.Range["A1"].HtmlString;
//Saving the workbook as stream
FileStream stream = new FileStream("BorderSettings.xlsx", FileMode.Create, FileAccess.ReadWrite);
workbook.SaveAs(stream);
stream.Dispose();
}using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(3);
IWorksheet worksheet = workbook.Worksheets[0];
//Add HTML string
worksheet.Range["A1"].HtmlString = "<font style=\"color:red;font-family:Magneto;font-size:12px; \">Welcome Syncfusion</font>";
//Assign HTML string as text to different range
worksheet.Range["A2"].Text = worksheet.Range["A1"].HtmlString;
workbook.SaveAs("Output.xlsx");
}Using excelEngine As ExcelEngine = New ExcelEngine()
Dim application As IApplication = excelEngine.Excel
application.DefaultVersion = ExcelVersion.Excel2013
Dim workbook As IWorkbook = application.Workbooks.Create(3)
Dim worksheet As IWorksheet = workbook.Worksheets(0)
'Add HTML string
worksheet.Range("A1").HtmlString = "<font style=""color:red;font-family:Magneto;font-size:12px; "">Welcome Syncfusion</font>"
'Assign HTML string as text to different range
worksheet.Range("A2").Text = worksheet.Range("A1").HtmlString
workbook.SaveAs("Output.xlsx")

Supported Tags
The following are the list of tags supported in addition to HTML string.
- <p></p> - Defines a paragraph
- <font></font> - Defines font, color and size of text
- <h1….h6></h1…h6> - Defines HTML headings
- <a href></a> - Defines a hyperlink
- <i></i> - Defines italic text
- <u></u> - Underlines the text
- <b></b> - Defines bold text
- <sub></sub> - Defines subscript
- <sup></sup> - Defines superscript
- <br></br> - Inserts link break
- <strike></strike> - Strikes out the text
- <strong></strong> - Defines important text
These mentioned tags do support the following style attributes.
- Color
- Font-family
- Text-decoration
- Font-size
- Size
- Face
Rich-Text Formatting
You can format each character in a cell with different font styles. XlsIO reads and writes rich-text by using the IRichTextString interface.
NOTE
Currently XlsIO cannot process and write RTF codes to cells.
