What is JSON to CSV Converter?

The JSON to CSV Converter flattens arrays of JSON objects into standard Comma-Separated Values (CSV) suitable for opening in Microsoft Excel, Google Sheets, or importing into SQL databases.

It dynamically extracts all unique keys across all objects to construct a complete, unified header row, ensuring missing keys in sparse objects are cleanly populated as empty fields.

Includes automatic text escaping, quote wrapping, and UTF-8 Byte Order Mark (BOM) support to guarantee accented characters display flawlessly in Excel.

How to Use

  1. Paste your JSON array into the editor.
  2. The formatted CSV table is created automatically in real time.
  3. Click 'Copy' to copy the CSV, or 'Download File' to save as a .csv file.
  4. Click 'Sample' to quickly load sample JSON objects.

FAQ

Why do Excel spreadsheets sometimes show broken accented letters?
Excel requires a UTF-8 BOM (Byte Order Mark) to detect non-ASCII encoding. Our tool includes UTF-8 BOM compatibility when exporting.
