Runs in your browser — your data stays on your device
Free toolProduct teams often want API data in a spreadsheet by Friday. This free JSON to CSV converter turns an array of objects into CSV in your browser so JavaScript developers and students can export API responses for coding practice or quick analysis—without Excel macros or a server upload.
How to use the JSON to CSV Converter
- 1
Paste a JSON array of objects (or a single object).
- 2
Review row and column counts when conversion succeeds.
- 3
Copy the CSV output into Sheets, Excel, or a file.
Why flattening nested JSON matters
CSV is a table; JSON is a tree. Nested fields need a rule. This tool flattens objects with dot notation (meta.level) and stringifies arrays so beginners see a predictable table instead of a failed export.
JSON to CSV example
Convert the sample array of students with nested meta objects. You should see columns such as id, name, course, and meta.level in the CSV header row.
Guides and next steps
Privacy note
