What is a JSON to CSV converter?▼
A JSON to CSV converter transforms JSON data into a flat, tabular CSV format. This allows JSON files to be opened and analyzed in spreadsheet tools like Microsoft Excel and Google Sheets.
Can this tool convert nested JSON to CSV?▼
Yes. The converter uses a recursive flattening algorithm to handle nested objects. For example, a JSON field like { "user": { "name": "John" } } becomes a CSV column named "user.name".

Yes. Arrays are supported and are converted into CSV-compatible representations. Complex arrays may be stringified to preserve data integrity.
Should I format JSON before converting it to CSV?▼
Yes. Formatting and validating JSON first helps prevent conversion errors and ensures consistent output. You can use the JSON Formatter to clean your data before conversion.
