Podcast Chapter Timestamp Formatter

How to use this text tool

1. Paste the source text or load a plain-text file.
2. Choose only the options relevant to your intended output.
3. Select Format Chapters or press Ctrl/Cmd + Enter.
4. Review the result and its counts, then copy or download it.

What this tool does

Normalize podcast chapter timestamps, sort them chronologically, flag duplicates or invalid values, and output a clean chapter list.

The result is a writing aid, not a platform performance guarantee. Always review names, claims, links, mentions, timing, and platform-specific limits before publishing.

Example

Try the Sample button to load a realistic draft. The tool processes that draft using the selected options and returns a structured result with measurable counts.

Use cases

Podcast editors can clean export notes, producers can prepare hosting metadata, and video teams can adapt episode chapters for descriptions.

Tips for better output

• Include a descriptive title after every timestamp.
• Use hours when an episode runs past 59 minutes.
• Check chapter times against the final edited audio.
• Avoid two chapter titles at the exact same time.
• Start at 00:00 when the destination platform expects it.

Processing details

Each non-empty line is parsed as MM:SS, H:MM:SS, or a timestamp followed by a separator. Valid times are converted to seconds for sorting, then rendered in a consistent format. All processing is deterministic and runs locally in the current browser session.

Platform behavior and display rules can change. This page does not publish content, access an account, predict reach, or verify information outside the supplied text.
