Frequently Asked Questions
What JSON format is supported?
The converter supports arrays of objects and arrays of arrays. For best results, use an array of objects where each object has consistent keys.
How are nested objects handled?
Nested values are stringified as JSON text inside the CSV cell. For advanced flattening, preprocess your JSON before conversion.
Is my data uploaded to a server?
No. Conversion runs entirely in your browser. Your JSON data never leaves your device.
Can I choose a delimiter other than comma?
Yes. You can switch delimiters such as comma, tab, semicolon, and pipe when converting.
Can I convert CSV back to JSON?
Yes. Click the swap button to switch to the CSV → JSON converter.
Can I convert large JSON files?
Yes, for most files. Since processing happens in-browser, very large files may depend on your device memory and browser limits.
