Frequently asked questions
How are nested objects handled?
They are flattened into columns like address.city. Arrays inside a row are written as JSON text in one cell.
Is the JSON to CSV Converter free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
Should I use the generated output as-is?
Treat it as a strong starting point. Types are inferred from your sample, so review nullability, naming and edge cases before committing it.
