JSON is parsed and converted on your device.

Who Uses This Tool

Privacy and Limitations

Conversion happens in your browser. Nested JSON may need flattening or manual cleanup before it becomes a clean CSV table.

Helpful FAQ

What JSON shape converts best to CSV?

An array of flat objects with consistent keys converts best because each key can become a column.

What happens to nested objects?

Nested objects may be stringified or need flattening. Review complex JSON before relying on the CSV.

Can spreadsheet apps open the result?

Yes, though encoding and delimiter handling can vary by spreadsheet app and locale.

JSON to CSV Planning

CSV works best when the JSON has a predictable list of similar objects. Before converting, inspect whether every object uses the same keys and whether nested arrays or objects need to be flattened. Deeply nested JSON may require a custom export plan.

Choose column names that are clear to the person opening the spreadsheet later. If a field is optional, expect blank cells in the CSV. If a field contains lists, decide whether to join values into one cell or create separate rows.

After conversion, open the CSV and check row count, column order, special characters, and date values. Keep the source JSON until the spreadsheet has been accepted by the target workflow.
