About the JSON to CSV Converter
Turn API data and exports into a spreadsheet. Every object becomes a row and every key becomes a column; nested objects are flattened into columns like address.city, and arrays are kept as JSON text so nothing is lost. Quotes, commas and line breaks inside values are escaped correctly.
Your data is processed in the browser and never sent to a server, so it is safe to paste payloads that contain tokens or personal data.
How to use it
- Paste a JSON array of objects (or open a file).
- Choose the delimiter (semicolon works better for European Excel).
- Download the CSV and open it in your spreadsheet app.
Good to know
- Columns appear in the order keys are first seen.
- Objects with different keys are merged into one header; missing values are left empty.
