About Split Word

Split Word files when a thesis has to go to reviewers chapter by chapter, or a bundle of contracts needs to become separate agreements again. Choose where to cut: at every heading of the level you pick, or after each manual page break. Each part comes out as its own DOCX, named with its number and first line, like report_02 Methods.docx. For spreadsheets, Split Excel cuts a workbook by sheet, by the values in a column or every N rows.

Cuts are made at Word's built-in heading styles, Heading 1 to Heading 3. Titles that are only bold or larger text don't count, so apply a heading style first if yours were formatted by hand. Anything before the first heading, such as a cover page and table of contents, becomes part 01. Every part keeps the original styles, headers, footers and list numbering. When the edited chapters come back, Merge Word joins them into one document again.

How to use Split Word

  1. 1
    Upload the DOCX

    Click Choose file or drop the document on the page. Only DOCX works here, so save a DOC as DOCX first.

  2. 2
    Pick where to split

    Choose Headings and a Heading level, or Page breaks to cut after every manual page break.

  3. 3
    Click Split Word

    The document is cut in an isolated process. If no matching headings or page breaks turn up, you'll see a message and the task isn't counted.

  4. 4
    Download the parts

    Grab every part with Download all (ZIP), or save the documents one by one.

Why use Cubfile for this

  • Split at the level you choose

    Heading 1 gives one file per chapter, while Heading 2 or Heading 3 cuts at every section or subsection of that level.

  • Page break mode

    A file holding many letters, certificates or forms, with a page break between each, splits into one document per piece.

  • Formatting carried over

    Each part is cut from the original document, so styles, headers, footers, page setup and numbering stay as they were.

  • Readable file names

    Parts are numbered and carry their opening words, such as thesis_03 Results.docx, so you can tell them apart without opening them.

FAQ

Split Word: questions and answers

How does Split Word decide where one part ends?
At the heading style you choose. With Heading 1 selected, each Heading 1 paragraph starts a new file and everything up to the next one goes with it. In Page breaks mode, every manual page break (Ctrl+Enter) ends a part.
Why does it say there's nothing to split?
The headings are probably formatted by hand instead of with Word's Heading styles, or the file has no manual page breaks. Apply Heading 1 to the chapter titles in Word, or try the other mode. The failed attempt doesn't use up a task.
Can I split Word files saved as DOC?
Not directly, because this tool reads DOCX only. Open the DOC in Word or WPS, save it as DOCX and upload that copy.
Is Split Word free to use?
Yes. Visitors can run 2 tasks in total and free accounts 2 a day, for documents up to 50 MB. VIP has no daily cap and takes files up to 1 GB. However many parts come out, one document counts as one task.
What happens to my document after splitting?
The original and all its parts are deleted automatically one hour after the job, and you can remove them sooner from the result page. Uploads are encrypted and each job runs in its own isolated process.
