Convert CSV to JSON
Converts a CSV table to a JSON array with a preview of the result.
Converts a CSV table into a JSON array. The first row is read as the column headers.
How it works
- Paste your CSV

Quoted fields are handled correctly, even when they contain a comma or a line break.
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.
