Syncfusion DocIO is a .NET Word library used to create, read, edit and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can create a Word document in Azure Functions v1.

Steps to create a Word document in Azure Functions v1

Step 1: Create a new Azure Functions project.
Create a Azure Functions project

Step 2: Create a project name and select the location.
Create a project name

Step 3: Select function worker as .NET Framework.
Select function worker

Step 4: Install the Syncfusion.DocIO.AspNet NuGet package as a reference to your project from NuGet.org.
Install Syncfusion.DocIO.AspNet NuGet package

NOTE

Starting with v16.2.0.x, if you reference Syncfusion assemblies from trial setup or from the NuGet feed, you also have to add “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering Syncfusion license key in your application to use our components.

Step 4: Include the following namespaces in the Function1.cs file.

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;

Step 5: Add the following code snippet in Run method of Function1 class to perform create a Word document in Azure Functions and return the resultant Word document to client end.

// Creating a new document.
WordDocument document = new WordDocument();
//Adding a new section to the document.
WSection section = document.AddSection() as WSection;
//Set Margin of the section
section.PageSetup.Margins.All = 72;
//Set page size of the section
section.PageSetup.PageSize = new System.Drawing.SizeF(612, 792);

Step 7: Select the target as Azure and click Next button.
Select the target as Azure

Step 8: Select the Create new button.

Step 11: Click the Publish button.
Click Publish Button

Step 12: Publish has been succeed.
Publish succeeded

Step 13: Now, go to Azure portal and select the App Services. After running the service, click Get function URL by copying it. Then, paste it in the below client sample (which will request the Azure Functions, to perform create a Word document using the template Word document). You will get the output Word document as follows.

Create a Word document in Azure Functions v1

Steps to post the request to Azure Functions

Step 1: Create a console application to request the Azure Functions API.

Step 2: Add the following code snippet into Main method to post the request to Azure Functions with template Word document and get the resultant Word document.

//Reads the template Word document.
FileStream fs = new FileStream(@"../../Data/Input.docx", FileMode.Open, FileAccess.ReadWrite, FileShare.ReadWrite);
fs.Position = 0;
//Saves the Word document in memory stream.
MemoryStream inputStream = new MemoryStream();
fs.CopyTo(inputStream);
inputStream.Position = 0;
try
{
    Console.WriteLine("Please enter your Azure Functions URL :");
    string functionURL = Console.ReadLine();
    //Create HttpWebRequest with hosted azure functions URL.    
    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(functionURL);
    //Set request method as POST
    req.Method = "POST";
    //Get the request stream to save the Word document stream
    Stream stream = req.GetRequestStream();
    //Write the Word document stream into request stream
    stream.Write(inputStream.ToArray(), 0, inputStream.ToArray().Length);
    //Gets the responce from the Azure Functions.
    HttpWebResponse res = (HttpWebResponse)req.GetResponse();
    //Saves the Word document stream.
    FileStream fileStream = File.Create("Sample.docx");
    res.GetResponseStream().CopyTo(fileStream);
    //Dispose the streams
    inputStream.Dispose();
    fileStream.Dispose();
}
catch (Exception ex)
{
    throw;
}

From GitHub, you can download the console application and Azure Functions v1.
