Use C# to split a Word document into multiple smaller files, or to extract pages to a new file.

Why split a Word document using C#?

While working with your documents, you may come across scenarios where you want to split large documents into smaller ones.
When scanning books, images or articles, you need to do it fast and all together. But in the end, you may want to separate pages of a Word document or any other document.
By splitting a document, you don’t need to send or print information you don’t want to.

What does split API for C# do?

  • Multi-page Word documents are divided into separate Word documents.
  • Split operation divides a multi-page Word document by page number, odd/even pages and by page range (entering the page range can be divided according to the page number of documents).
  • Split one big file into many smaller, one-page files. You can split them into multiple files, in various page ranges.
  • Keep style and layout of the source document.

Where and how?

Luckily for you, Words Cloud API has the answer.
The ability to split documents is one of four main feature areas of Words Cloud. It provides the simplest API to split a Word document within MS Word documents or other file formats.
Using an API client is the quickest way for a C# developer to speed up the development. API takes care of low-level details to make requests and handle responses. And this lets you focus on writing code specific to your particular project.
