What JSON structure does the JSON→CSV converter accept?

It expects an array of objects at the top level, e.g. [{"name":"Alice","age":30},{"name":"Bob","age":25}]. Nested objects are stringified into the cell value.

Does the CSV→JSON converter handle quoted fields?

Yes. Fields wrapped in double quotes (including those containing commas or newlines) are parsed correctly.

Are my files uploaded anywhere?

No. All conversion happens in your browser using JavaScript. Nothing is sent to a server.

Does the JSON to CSV converter handle nested objects?

Nested objects and arrays are serialised as JSON strings within the CSV cell rather than being flattened into separate columns. If you need flat columns, flatten your JSON structure before converting.

Can I open the CSV output in Excel or Google Sheets?

Yes. Copy the CSV output and paste it into a new Google Sheet, or save it as a .csv file and open it in Excel. Both applications detect comma-separated values automatically.
