JSON to CSV Converter
Transform structured objects into flat, usable data.
Arrays become rows. Keys become columns.
Client-side processing
No data leaves your browser.
Quick guide
Paste a JSON array where each object represents a row. The converter extracts all keys, builds CSV headers, and aligns values across rows.
Use this for API exports, reporting pipelines, and quick data analysis in spreadsheets or BI tools.
Real example
Input:
[{"name":"Ana","score":9},{"name":"Ben","score":8}]
Output:
name,score
"Ana",9
"Ben",8
