YAML Frontmatter Editor

Paste a Markdown file or YAML frontmatter block and edit each field in a clean form. Add, remove, or update fields — then copy the result back.

What is YAML frontmatter?

YAML frontmatter is a metadata block at the top of a Markdown file, enclosed in triple-dashed lines (---). Static site generators — Jekyll, Hugo, Docusaurus, Eleventy, and others — use it to store page properties: title, publication date, author, tags, draft status, custom layout, and more.

How this tool helps

Paste your Markdown file (or just the YAML block itself) and the editor parses the frontmatter into an editable field-by-field interface. Change values, add new fields, remove unused keys, then copy the updated YAML block — or the full file with the new frontmatter in place — back to your clipboard.

Common use cases

  • Jekyll blogs — update title, tags, categories, layout, and permalink without touching the file in a text editor
  • Hugo sites — toggle draft status, update aliases, modify weight and taxonomy fields
  • Docusaurus docs — edit sidebar labels, custom IDs, pagination controls, and tags
  • Eleventy — manage tags, permalink slugs, and layout keys
  • Content auditing — quickly review what metadata fields a post has without parsing the YAML manually

Supported value formats

  • Strings: title: My Post or quoted title: "My Post, With Commas"
  • Booleans: draft: true / draft: false
  • Numbers: weight: 10
  • Inline arrays: tags: [markdown, tutorial, beginner]
  • Dates: date: 2026-05-22
