How to split a single Word DOCX into Separate Documents by Page in C# .NET Framework

Today’s lesson will demonstrate for you how to break up a DOCX file into multiple DOCX files, each containing exactly one page of content.

Right out of the gate, we need to begin with installation of our API client. Run this command in Package Manager, and that’s all there is to it.

Install-Package Cloudmersive.APIClient.NET.DocumentAndDataConvert -Version 2.2.0

Now we can run SplitDocumentDocx on our document in question.

using System;
using System.Diagnostics;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Api;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Client;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Model;
namespace Example
{
public class SplitDocumentDocxExample
{
public void main()
{
// Configure API key authorization: Apikey
Configuration.Default.AddApiKey("Apikey", "YOUR_API_KEY");
// Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
// Configuration.Default.AddApiKeyPrefix("Apikey", "Bearer");
var apiInstance = new SplitDocumentApi();
var inputFile = new System.IO.Stream(); // System.IO.Stream | Input file to perform the operation on.
var returnDocumentContents = true;  // bool? | Set to true to return the contents of each Worksheet directly, set to false to only return URLs to each resulting document.  Default is true. (optional)
try
{
// Split a single Word Document DOCX into Separate Documents by Page
SplitDocxDocumentResult result = apiInstance.SplitDocumentDocx(inputFile, returnDocumentContents);
Debug.WriteLine(result);
}
catch (Exception e)
{
Debug.Print("Exception when calling SplitDocumentApi.SplitDocumentDocx: " + e.Message );
}
}
}
}
