Table of Contents Generator — Free Online Tool
Auto-generate a table of contents from headings
How to use this tool
- [01]Paste your document or HTML containing H2, H3, and H4 headings.
- [02]Review the generated hierarchy — gaps or odd nesting usually mean the document structure needs fixing.
- [03]Copy the linked list into your page, and avoid renaming headings later since that breaks existing deep links.
About this Table of Contents Generator
The Table of Contents Generator reads the headings in a document or HTML block and builds a nested, linked contents list from the H2, H3, and H4 structure, complete with anchor links to each section.
Two things make this more than a convenience. First, it exposes your heading structure, and a table of contents that looks wrong is almost always telling you the document's hierarchy is wrong — an H4 nested directly under an H2 with no H3 between, or three consecutive sections at the same level that should be grouped. Fixing what the contents list reveals improves the document for readers and for screen reader users navigating by heading.
Second, on a published page a linked contents list is one of the more reliable ways to earn jump links in Google's search results — the indented sub-links that appear under a result and take a searcher directly to a section. Google generates those from on-page anchor structure, and a long article without one forfeits the extra search real estate and the click-through that comes with it.
The anchor slugs it generates matter for stability: once a section link is published and shared, changing the heading text changes the anchor and breaks every existing deep link to it, which is worth knowing before renaming sections in a page that is already live.
