YouTube Chapter Formatter
Convert rough video timestamps into a clean YouTube chapter list. The formatter accepts timestamps followed by titles, normalizes hour, minute, and second fields, sorts entries by time, removes duplicate timestamps, and flags gaps or a missing 0:00 opening chapter. You can choose a title style and add sequential numbering. The output remains plain text that can be pasted directly into a video description after you verify each timestamp.

The page parses only the supplied text, applies the visible rules and options, and reports counts from the actual result. No external API is called.
Always compare the result with the original source and the latest requirements of the publishing platform.

Processing details
All parsing and generation happens locally with JavaScript. Metrics use Unicode-aware character or word matching where relevant, and exports are created from the displayed result.
This tool cannot verify identities, credentials, analytics data, platform limits, search impact, or how text will render in every app and device.
Frequently asked questions
Does the YouTube Chapter Formatter send my text to a server?
No. The processing in this page runs in your browser. Files and pasted text are not uploaded by the tool.
Can I use the YouTube Chapter Formatter output without reviewing it?
Review the result before publishing. Automated formatting cannot confirm factual accuracy, platform rules, links, timing, or context.
What happens if my input format is inconsistent?
Recognized lines are processed and the result summary reports invalid, removed, or unusual items when the tool can identify them.
Does this tool guarantee better reach or search rankings?
No. It organizes or evaluates text; it cannot predict distribution, engagement, search rankings, or business outcomes.
Can I download the result from this YouTube Chapter Formatter?
Yes. After running the tool, use Download TXT. Structured CSV or JSON downloads appear only when the result supports them.
