KDP Manuscript Validator for Word Docs

Getting a Word document past Amazon's quirky Kindle requirements can feel like a guessing game — until you run it through the KDP Manuscript Validator. Drop in your .docx and you'll get a plain-English compliance report in seconds, no uploads to shady third parties, no guesswork about why your last upload got rejected. The KDP Manuscript Validator scans your file for the stuff Amazon actually cares about: stray headers and footers, weird font choices, broken heading hierarchy, empty paragraphs cluttering your manuscript, and image embedding issues that quietly break your eBook. If you've ever stared at a 'manuscript not accepted' email wondering what went wrong, this is the sanity check

How to use KDP Manuscript Validator for Word Docs

  1. Export your manuscript as .docx. Save your book file as a Word document (.docx). Google Docs, Pages, and Scrivener can all export to this format.
  2. Drop the file into the KDP Manuscript Validator. Drag and drop your .docx onto the upload area, or click to browse. Everything runs in your browser — your manuscript never leaves your machine.
  3. Review the compliance report. You'll get a categorized breakdown: headers/footers, font issues, heading hierarchy gaps, empty paragraphs, image embedding problems, and any other flags.
  4. Fix the flagged items in Word. Open your document and address each issue. Most fixes take seconds — removing a stray header, normalizing a font, or cleaning up empty paragraphs.
  5. Re-validate before uploading. Run the file through again to confirm everything's clean. A green report means you're ready for KDP.
  6. Upload to KDP with confidence. Head to Kindle Direct Publishing and submit. Knowing your file is compliant means fewer rejections and faster time-to-publish.

Frequently asked

What does the KDP Manuscript Validator actually check? It scans for headers and footers (which KDP strips or mishandles), unsupported or unusual fonts, broken heading hierarchy, empty paragraphs that mess with eBook flow, and images that aren't properly embedded — plus a handful of other common pitfalls.
Is my manuscript uploaded to a server? Nope. The validator processes your .docx locally in your browser, so your work-in-progress never leaves your machine.
Does this guarantee my book will pass KDP review? It catches the technical formatting issues Amazon's automated checks care about. Content review (copyright, metadata, cover specs) is separate — but the manuscript side will be solid.
Can I use this for both eBook and paperback files? It's tuned for eBook manuscript files (.docx), where formatting quirks bite hardest. Paperback interiors have different requirements that aren't fully covered here.
What file formats does it accept? Just .docx for now — the modern Word format. If you have an older .doc or an .odt, convert it to .docx first.
Why are empty paragraphs a problem? Amazon's converter treats them as intentional spacing, which can create awkward gaps or page breaks in the final eBook. The validator flags them so you can clean them up before publishing.
Does it check spelling or grammar? No — this is strictly a formatting and compliance tool. For copy issues, use a proofreading tool. For KDP technical readiness, you're in the right place.
