Frequently asked questions
- What JSON shape does it accept?
- An array at the top level — either an array of objects (the keys become the column headers) or an array of arrays (each inner array is a row). Nested objects and arrays in a cell are written as JSON text.
- How are commas and quotes inside values handled?
- Any value containing the delimiter, a double quote or a line break is wrapped in double quotes, and embedded quotes are doubled, following the RFC 4180 CSV rules so the file opens correctly in Excel and Google Sheets.
- Is my data uploaded anywhere?
- No. Conversion runs entirely in your browser — your JSON never leaves your device.
