YAML to CSV

Paste a YAML document and get a real table: one row per list item, columns from the keys — ready to export as CSV, JSON, HTML or Markdown.

Everything runs in your browser: the text is never uploaded.

Paste some YAML first.

How it works

  1. 1.Paste YAML: a list of mappings is the most common shape (one row per item, keys become columns).
  2. 2.Run it. Nested mappings become dotted column names, scalar lists are joined with commas, object lists are numbered.
  3. 3.Check the preview — if the YAML is broken the error names the line instead of showing a half-empty table.
  4. 4.Choose the export format (CSV, JSON, HTML or Markdown), then copy or download.
