About this tool

Paste a JSON array or CSV data and the format is auto-detected. JSON is converted to CSV with proper escaping, and CSV is converted to a JSON array of objects. A table preview shows up to 50 rows so you can verify the result before copying. No data leaves your browser.

Frequently Asked Questions

What JSON structure does this support?

The input should be a JSON array of objects where all objects share the same keys. Those keys become the CSV column headers.

How are commas inside values handled?

Values containing commas, quotes, or newlines are automatically wrapped in double quotes and escaped per the CSV standard (RFC 4180).

Is my data uploaded anywhere?

No. All conversion and the table preview happen entirely in your browser.
