About the JSON ↔ CSV Converter

Spreadsheets need rows and columns, not nested JSON. This free JSON to CSV converter turns a JSON array of objects into CSV you can open in Excel or Google Sheets, and converts CSV back to JSON too — handling quoting, commas and newlines correctly so your data doesn't break.

Conversion happens in your browser; nothing is uploaded.

How to convert JSON to CSV (and back)

  • Paste a JSON array of objects to get CSV with a header row from the keys.
  • Or paste CSV to convert it back into a JSON array.
  • Values containing commas, quotes or line breaks are escaped correctly.

Getting JSON into a spreadsheet

Spreadsheets want rows and columns, not nested objects. Converting a JSON array of objects to CSV gives you a header row from the keys and one row per record, ready to open in Excel or Google Sheets. Going the other way turns exported CSV back into JSON for an API or script. Values containing commas, quotes or line breaks are escaped correctly so nothing breaks.
