How It Works
Paste a JSON array of objects and the tool converts it to CSV format with auto-detected headers from object keys. Download the CSV or copy it to paste into spreadsheets. Handles nested objects by flattening keys with dot notation.
When to Use It

- Data migration — convert JSON data to CSV for import into systems that only accept CSV uploads.
Frequently Asked Questions
How are nested objects handled?
Nested objects are flattened using dot notation (e.g., address.city becomes a column header). Arrays within objects are joined with commas.
What delimiter is used?
The output uses commas as the standard CSV delimiter. If your data contains commas, values are automatically wrapped in double quotes per the CSV specification.
Can I convert CSV back to JSON?
Yes. Use our CSV to JSON converter tool for the reverse operation. Both tools process data entirely in your browser.
No data is sent to any server. All processing happens in your browser.
