JSON to CSV Converter

Convert JSON arrays to CSV spreadsheets instantly.

About this tool

APIs speak JSON, but spreadsheets speak CSV. When you need to analyze API data in Excel or Google Sheets, this free converter bridges the gap: paste a JSON array of objects and get a properly formatted CSV instantly, headers from your keys, one row per object, correct quoting throughout.

It handles the details that break naive conversions: values with commas, quotes, or line breaks are escaped per the CSV standard so they open correctly in spreadsheet apps. Nested objects can be flattened into dot-notation columns instead of being silently dropped.
