How to use this tool
Convert tabular JSON data to CSV, or inspect CSV as structured JSON. This is handy for small exports, fixtures, and spreadsheet handoffs.
Suggested workflow
- Choose the input format.
- Paste an array of records or CSV rows.
- Check column names and download or copy the converted result.
Good to know
Nested objects need to be flattened deliberately; CSV has no native representation for nested records.
