The JSON to CSV converter transforms a JSON array of objects into a comma-separated values file. The keys from the first object become column headers, and each object becomes a row. Values with commas or quotes are automatically escaped according to RFC 4180.

How to Convert JSON to CSV
JSON APIs return data in object format, but spreadsheet tools like Excel and Google Sheets work best with CSV. The JSON to CSV converter bridges this gap, converting API response arrays into importable CSV files in seconds.
Step 1: Paste Your JSON Array
Your JSON must be an array of objects — each object with the same or similar keys. The first object's keys become the CSV column headers. Objects missing certain keys will have empty cells in those columns.
Step 2: Convert and Download
Click Convert to CSV to process the data. Click Download CSV to save the file, or Copy to place the content on your clipboard for pasting into a spreadsheet.
Frequently Asked Questions
Is this JSON to CSV converter free?
Yes, completely free with no signup. All conversion runs locally in your browser.
What JSON format is supported?
The tool expects a JSON array of objects, where each object becomes a CSV row. The keys of the first object become the column headers. Nested objects are stringified.
How are nested objects handled?
Nested objects and arrays are JSON-stringified and placed in the corresponding CSV cell. For complex nested structures, you may want to flatten the JSON first.
Can I download the CSV output?
Yes. Click the Download CSV button to save the output as a .csv file that can be opened in Excel, Google Sheets, or any spreadsheet application.
How are special characters handled?
Values containing commas, quotes, or newlines are automatically wrapped in double quotes with internal quotes escaped as double-double-quotes, following the RFC 4180 CSV standard.
