Frequently Asked Questions

Does it handle commas inside quoted CSV fields?

Yes, values wrapped in double quotes (including quoted commas or newlines) are parsed correctly.

What if my JSON objects have different keys?

The CSV header is taken from the first object's keys — make sure all objects share the same structure for a clean export.

Is my data uploaded anywhere?

No, both conversions run entirely in your browser.
