FAQ
Questions before you begin
Are commas inside CSV fields supported?
Yes. Common double-quoted fields, escaped quotes and line breaks are parsed.
Can JSON have any shape?
For reliable tabular conversion, input must be an object or object array; nested values are serialized as JSON text.
Is the data retained?
No. Parsing and download happen in the current browser.
