Split documents using REST API in Go

This Go library provides Go developers with the ability to work with a document split function using REST API. It allows you to split one document into several smaller files online in Go. For example, you may need to email a few pages from your document, or you may want to show a customer only a part of your file. All this can be done through the document split functionality in Go code.

Various methods can be used for document splitting: 'by page', 'by page ranges', 'by headings', 'by section break'. Just load the original document and choose the method you need. Make sure your document uses the required heading styles or contains section breaks if you want to split your file according to these criteria using Go code. After splitting a document you can export the result as separate document pages or smaller files.
