Frequently Asked Questions
How do I convert CSV to JSON?
Paste CSV with a header row into the input box. A JSON array of objects appears in the output, one object per row.
Does it handle quoted values with commas?
Yes. The parser follows the standard CSV rules, so a value like "Turing, Alan" stays intact.
Will numbers stay numbers?
With type inference on, numeric and true/false values become real JSON types. Turn it off to keep every value as a string.
Is my CSV sent to a server?
No. Parsing happens in your browser and the data never leaves your device.
