Create a linked table of contents and heading IDs from HTML or Markdown headings.
A table of contents generator reads your headings and returns a ready-to-paste linked list plus the heading IDs it needs. A visible contents list improves usability and can earn jump links in search results.
It runs entirely in your browser. Nothing you paste or upload is sent to a server or stored.
Results appear as you run it, with nothing to install and no waiting on a queue.
Each finding says what it means and what to do next, not just a raw value.
Copy the output straight into your CMS, spreadsheet, ticket or client report.
Your content stays on your device. We do not receive or keep it.
HTML or Markdown.
A nested list is created.
Match each heading with its anchor.
The output is a linked list that mirrors your heading structure, plus IDs that each heading needs for the links to work. Check that the list reads like a clear summary of the article: if entries look vague or repeated, rewrite the headings instead of the list. Paste the contents block near the top of the article and make sure each heading in your HTML carries the matching ID. Test every link in a browser to confirm it jumps to the right place. For long pages the list helps readers and may produce jump links in search results, though that is never guaranteed. Update the list whenever you add, rename or reorder sections, so links do not break.
A common mistake is pasting the list without adding the heading IDs, so every link does nothing. Another is including every H3 and H4 in a short article, which makes the list longer than the content. Avoid duplicate heading text, since it can generate identical IDs and send readers to the wrong section. Do not forget to change IDs and links together when renaming a heading. Watch out for sticky headers that hide the target heading after the jump; add scroll margin in CSS if needed. Also avoid treating a contents list as a ranking trick; its value is helping readers navigate the page.
