Convert JSON to CSV
Turns a JSON array into a downloadable CSV table.
Turns a JSON array into a CSV table you can open in Excel or Google Sheets.
How it works
- Paste your JSON array
- Convert
- Download the CSV
Every key that appears anywhere becomes a column, so no field is lost even if it is missing from some objects.
Frequently asked
What does it cost?
Every tool shows its price before you start. Tools marked free run in your browser and never cost anything — no sign-up needed.
What happens if processing fails?
You are not charged. We only charge when a result is actually produced; if the run fails, the charge is reversed.
What happens to my files?
Uploaded files are processed in memory for that one request and then discarded. We do not store them, and their contents never reach our logs or analytics.
Do you use my own API key?
No. Your BYOK key belongs to the Playground and is never used for these tools.
