Frequently Asked Questions
How is JSON converted to CSV in the browser?
The conversion is powered by PapaParse unparse engine. It extracts all distinct object keys as header columns and serializes the array rows with proper escaping.
Can it handle nested JSON objects?
For best tabular results, use a flat array of objects. Nested objects are serialized as JSON string values inside the column cell.
Are my JSON arrays uploaded to any server?
No! 100% of data conversion occurs locally in your browser. No data leaves your machine.
Can I export TSV (tab-separated) files for Excel?
Yes! Select the "Tab (\t)" delimiter option in the top controls to generate TSV output that pastes seamlessly into Microsoft Excel and Google Sheets.
