Frequently Asked Questions
What JSON shapes can it convert?
An array of objects works best (each object becomes a row). A single object is converted to a one-row CSV. Nested objects and arrays are serialized as JSON strings inside their cells.
Is my data uploaded anywhere?
No. Parsing and CSV generation happen entirely in your browser with JavaScript. Nothing is sent to any server.
