Table of contents


  • Run command "Create Table of Contents" (in the VS Code Command Palette) to insert a new table of contents.

  • The TOC is automatically updated on file save by default. To disable, please change the toc.updateOnSave option.

  • The indentation type (tab or spaces) of TOC can be configured per file. Find the setting in the right bottom corner of VS Code's status bar.

    Note: Be sure to also check the list.indentationSize option.

  • To make TOC compatible with GitHub or GitLab, set option slugifyMode accordingly

  • Three ways to control which headings are present in the TOC:

    Click to expand
    1. Add <!-- omit in toc --> at the end of a heading to ignore it in TOC
      (It can also be placed above a heading)

    2. Use toc.levels setting.

    3. You can also use the toc.omittedFromToc setting to omit some headings (and their subheadings) from TOC:

      // In your settings.json
      "markdown.extension.toc.omittedFromToc": {
        // Use a path relative to your workspace.
        "": [
            "# Introduction",
            "## Also omitted",
        // Or an absolute path for standalone files.
        "/home/foo/Documents/": [
          "## Shame list (I'll never do these)",


      • Setext headings (underlined with === or ---) can also be omitted, just put their # and ## versions in the setting, respectively.
      • When omitting heading, make sure headings within a document are unique. Duplicate headings may lead to unpredictable behavior.
  • Easily add/update/remove section numbering

    section numbers
  • In case you are seeing unexpected TOC recognition, you can add a <!-- no toc --> comment above the list.

List editing

on enter key

on tab/backspace key

fix ordered list markers

Note: By default, this extension tries to determine indentation size for different lists according to CommonMark Spec. If you prefer to use a fixed tab size, please change the list.indentationSize setting.

Print Markdown to HTML

  • Commands Markdown: Print current document to HTML and Markdown: Print documents to HTML (batch mode)

  • Compatible with other installed Markdown plugins (e.g. Markdown Footnotes) The exported HTML should look the same as inside VSCode.

  • Use comment <!-- title: Your Title --> to specify a title of the exported HTML.

  • Plain links to .md files will be converted to .html.

  • It's recommended to print the exported HTML to PDF with browser (e.g. Chrome) if you want to share your documents with others.

Q: Error "command 'markdown.extension.onXXXKey' not found"

In most cases, it is because VSCode needs a few seconds to load this extension when you open a Markdown file for the first time. (You will see a message "Activating Extensions..." on the status bar.)

If you still see this "command not found" error after waiting for a long time, please try to restart VSCode (or reinstall this extension1 if needed). Otherwise feel free to open a new issue on GitHub.

1. uninstall this extension, restart VSCode (important!) and then reinstall

Q: Which Markdown syntax is supported?

For other Markdown syntax, you need to install the corresponding extensions from VSCode marketplace (e.g. Mermaid diagram, emoji, footnotes and superscript). Once installed, they will take effect in VSCode and also the exported HTML file.

Q: This extension has overridden some of my key bindings (e.g. Ctrl + B, Alt + C)

You can easily manage key bindings with VSCode's "Keyboard Shortcuts" page. (Commands provided by this extension have prefix markdown.extension.)

Q: The extension is unresponsive, causing lag etc. (performance issues)

From experience, there is a good chance that the performance issues are caused by other extensions (e.g., some spell checker extensions).

This can be verified if you try again with all other extensions disabled (execute Developer: Reload with Extensions Disabled or Extensions: Disable All Installed Extensions for this Workspace in the VS Code command Palette) and then enable this extension.

To find out the root cause, you can install our development build (debug.vsix) and create a CPU profile following this official instruction from the VS Code. And then please open a GitHub issue with that profile (.cpuprofile.txt) attached.


See CHANGELOG for more information.

Latest Development Build

Download it here, please click the latest passing event to download artifacts. There are two versions: markdown-all-in-one-*.vsix is the regular build, while debug.vsix is used to create a verbose CPU profile.

To install, execute Extensions: Install from VSIX... in the VS Code Command Palette (ctrl + shift + p)
