When you reformat a Word document for Kindle or EPUB, the hidden issues — double spaces between sentences, straight quotes, stacked blank paragraphs, stray bold or italic runs — follow the file unless you catch them first. Upload your .docx and this Word Manuscript Cleanup Checker flags every instance in seconds, so you can fix them before converting. Free, no signup, runs entirely in your browser.

.docx only — processed locally, never uploaded
Before you send a manuscript to a formatter, editor, or KDP, run it through a quick technical scan. This tool reads your .docx file directly in your browser and reports formatting issues that are easy to miss after months of writing and revising — double spaces, straight quotes, stacked blank paragraphs, and manually-applied bold or italic formatting.
Six checks run automatically: double spaces, blank paragraph stacking, trailing spaces at the end of paragraphs, double hyphens that should likely be em dashes, straight quote marks instead of curly quotes, and text runs with bold or italic applied directly rather than through a heading style.
Your file never leaves your device. It's parsed with JavaScript in your browser tab and discarded when you close or refresh the page. This is a report-only tool for now — it flags issues but doesn't rewrite your file.
Authors doing a final technical check before formatting or upload. Freelance editors validating a manuscript before handing it back to a client. Anyone who wants a fast, free second opinion on a .docx file before it goes further down the pipeline.
