About this tool
Convert JSON arrays to CSV spreadsheets. Useful when reviewing API responses, cleaning config before commit, or sharing readable snippets in docs and PRs.
Paste a JSON array of objects into Input (each object becomes a row). Click Convert to produce CSV with a header row from object keys. Example — Export order lines as CSV: try `[{"sku":"A-100","qty":3,"price":9.5},{"sku":"B-200","qty":1,"price":24}]` and expect something like `sku,qty,price A-100,3,9.5 B-200,1,24`.
Nested objects and arrays are flattened poorly — flatten or stringify them before converting. See also: CSV to JSON, and JSON Formatter. Runs in your browser — nothing you paste gets uploaded.
How to use
- Paste a JSON array of objects into Input (each object becomes a row).
- Click Convert to produce CSV with a header row from object keys.
- Copy into a spreadsheet or data pipeline.
- Align keys across objects so columns stay consistent.
Example
Export order lines as CSV
Input
[{"sku":"A-100","qty":3,"price":9.5},{"sku":"B-200","qty":1,"price":24}]Output
sku,qty,price A-100,3,9.5 B-200,1,24
Limitations
- Nested objects and arrays are flattened poorly — flatten or stringify them before converting.
- Input must be an array of objects; a bare object or array of primitives will error.
- Delimiter and quoting follow Papa Parse defaults; exotic dialects may need a dedicated ETL tool.
