Paste a JSON array of objects to get a downloadable CSV file instantly. Use our free JSON to CSV converter online to process your data directly inside your browser without uploading it to any server.
Your JSON is processed locally in your browser and is not uploaded to our server.
How Our JSON to CSV Converter Online Works
This tool reads every object in your JSON array and builds one CSV column per unique field name it finds. Afterwards, it organizes the values in the order those fields first appear. Consequently, you receive a clean spreadsheet that Microsoft Excel and Google Sheets open seamlessly.
However, a value that contains a nested object or array converts directly to JSON text rather than flattening into separate columns. Therefore, we recommend keeping your input to flat objects for the cleanest results.
If you work with developer utilities, you can also transform structured data using our CSV to JSON Converter or inspect security tokens with our JWT Decoder & Inspector.
FAQ
What happens if my JSON objects have different fields?
The resulting CSV includes every field seen across all objects as a column. Consequently, any object missing a specific field receives an empty cell for that column.
Does this online JSON-to-CSV converter handle commas and quotes?
Yes, absolutely. The tool wraps any value containing a comma, quote, or line break inside standard escaping rules. As a result, your formatted data remains fully compliant with standard CSV specifications.
Is my JSON data uploaded to any external server?
No, never. The entire conversion process runs locally inside your web browser. Therefore, your private API responses and structural data remain completely confidential. You can learn more about standard JSON formats on the ECMA International Standards Website.
