How to Use This JSON to CSV Converter
Paste a JSON object or array, choose the delimiter, decide whether headers and flattening should be enabled, then export the CSV output.
Set the delimiter and header options
Choose comma, semicolon, tab, or pipe as the delimiter to match the spreadsheet or import tool you are targeting. Keep headers enabled unless the destination expects headerless rows.
Enable flattening for nested objects
If your JSON has nested objects, check Flatten to expand them into dot-notation column names like address.city instead of dropping or serializing the nested values.
Preview, copy, or download
Review the first rows in the preview table before copying the CSV output or downloading the file. This catches column mismatches before the data reaches the destination.
