What CSV and JSON Converter does

Convert CSV and JSON with delimiter and header controls.

How to use it

  1. Choose CSV to JSON or JSON to CSV and enter input text.
  2. Set one delimiter character and whether to include a header row. JSON input must be an array of objects.
  3. Inspect the first 100 table rows, then copy or save the complete result. CSV exports prefix formula-like cells with an apostrophe.

Formats and limits

  • CSV text or a JSON array of objects, up to 2 MB. Preview the first 100 rows and save converted.csv or converted.json.
