Summary

This tool converts a YAML document containing an array of objects into a CSV file entirely in your browser. It automatically detects all unique keys across every record and uses them as column headers. No data is sent to any server — parsing and export happen locally using js-yaml.

How it works

  1. Paste or type your YAML array-of-objects into the input panel.
  2. The tool parses the YAML and extracts all unique keys from every record.
  3. A live preview table is rendered so you can verify the column mapping.
  4. Click "Download CSV" to save the file, or "Copy CSV" to copy the text.
  5. Use the delimiter selector to choose comma, semicolon, or tab separation.

Use cases

  • Convert API fixture files or test datasets to CSV for QA review.
  • Transform YAML-based CMS content exports into CSV for bulk import.
  • Share structured YAML data with stakeholders who prefer Excel or Google Sheets.
  • Quickly inspect YAML list data in a tabular view without installing tools.
