CSV output
How this JSON to CSV converter works
Paste a JSON array like [{"name":"Ada","age":36}] and press Convert. The converter collects every unique key across your objects to build the CSV header, then emits one row per object. Missing keys become empty cells, so ragged arrays still produce a clean rectangle.
Why convert JSON to CSV?
CSV opens natively in Excel, Google Sheets and Numbers; JSON doesn't. Converting an API response or data export to CSV is the fastest way to share it with non-technical teammates, build a chart, or diff two datasets side by side.
