About JSON to CSV
JSON arrays of flat objects map cleanly to CSV rows: object keys become column headers and each object becomes a row.
Nested objects or arrays need flattening or special handling—this tool targets simple, table-shaped JSON common in exports and APIs.
Conversion is local so sensitive spreadsheets never leave your device during the transform step.

Frequently asked questions
- What shape of JSON works best?
- An array of objects with the same keys, e.g. [{"name":"Ada","age":36}, …]. Deep nesting may need preprocessing.
- Are commas escaped?
- CSV fields that contain commas should be quoted. Check the output if your data has special characters.
