Overview

The Markdown TOC Generator automatically creates a structured table of contents from your Markdown headings. It generates GitHub-style anchor links, allowing readers to navigate long documents, READMEs, or wiki pages with ease.

When to use

  • When writing long-form documentation or README files that need a clear navigation structure.
  • When you want to automatically generate GitHub-compatible anchor links for your Markdown headings.
  • When formatting wiki pages or technical blogs where readers benefit from a quick overview of the content outline.

How it works

  1. 1Paste your raw Markdown text into the input area.
  2. 2Configure your preferences, such as the minimum and maximum heading levels (H1 to H6), list style, and indentation.
  3. 3Choose whether to include anchor links and select your desired output format (Markdown, HTML, or both).
  4. 4Copy the generated table of contents directly into your document.

Use cases

  • Generating a table of contents for a project README.md file on GitHub.
  • Creating structured navigation outlines for technical documentation and user guides.
  • Formatting blog posts written in Markdown to improve readability and SEO structure.

Examples

1. GitHub README Navigation

Open Source Developer

Background

A developer is publishing a new open-source library and has written a comprehensive README.md file with multiple sections.

Problem

The README is very long, making it difficult for users to find installation instructions and API references quickly.

How to use

Paste the README content into the input, set the minimum heading level to H2, select 'Unordered' list style, and enable 'Include Anchor Links'.

minLevel: 2, maxLevel: 6, listStyle: unordered, indent: 2spaces, includeAnchor: true, outputFormat: markdown

Outcome

A clean, clickable Markdown list of H2-H6 headings with GitHub-compatible anchor links ready to paste at the top of the README.

2. Technical Documentation Outline

Technical Writer

Background

A technical writer is drafting a software user manual in Markdown and needs an HTML-formatted table of contents for a web portal.

Problem

The manual needs a structured, nested HTML list of headings from H1 to H3 to embed directly into a web template.

How to use
