Frequently Asked Questions

What JSON format does the converter accept?

The converter works best with a JSON array of objects, e.g., [{"name":"Alice","age":30}]. A single object is also accepted and will produce a one-row CSV. Nested objects are serialized as JSON strings within CSV cells.

How are nested objects handled in the CSV?

Nested objects and arrays are automatically converted to their JSON string representation within the CSV cell. This preserves the data while keeping the CSV format valid.

Can I convert large JSON files?

Yes. The converter runs entirely in your browser, so there is no upload limit. Very large datasets (10,000+ rows) will work but may take a moment to process depending on your device.

Is my JSON data secure?

Absolutely. All conversion happens client-side in your browser. Your JSON data is never sent to any server, ensuring complete privacy.

How do I open the CSV in Excel?

Copy the CSV output and paste it into a text file with a .csv extension, then open it in Excel. Alternatively, paste directly into Google Sheets using Edit → Paste special → Paste as CSV.
