How to use the YAML to CSV Converter

  1. Paste a YAML list (or a document containing one).
  2. Choose the delimiter your spreadsheet expects.
  3. Download the CSV and open it in Excel or Sheets.

What does this tool do?

Every item in the list becomes a row and every key becomes a column. Nested objects are flattened into columns like address.city, and arrays are joined with semicolons. Values containing commas, quotes or line breaks are quoted correctly.

Everything runs in your browser — nothing you paste is uploaded.

Why use it?

  • Flattens nested keys.
  • Excel-friendly delimiters.
  • Proper CSV quoting.
