How to use JSON to CSV
Paste or upload your JSON
Drop one or more .json files into the editor, or paste an array of objects straight from an API response. Nothing is transmitted anywhere.
Parsefy flattens the structure
Nested objects become dot-notation columns such as user.address.city. Choose Multiple output and repeated arrays are split into their own related tables instead.
Copy or download the CSV
Take the result as a single CSV file, or as a ZIP of related tables when you split arrays — ready for Excel, Google Sheets or a database import.
