Frequently asked questions
What JSON format does it accept?
A JSON array of objects, like [{"name":"Asha"},{"name":"Rahim"}]. A single object is also accepted and becomes one row.
What happens to nested objects or arrays?
Nested values are flattened into JSON text inside the cell, so no data is lost — but flat objects give the cleanest spreadsheet.
Is my data uploaded anywhere?
No. Conversion runs entirely in your browser — your data never leaves your device.
How are commas and quotes handled?
Fields containing commas, quotes or line breaks are wrapped in double quotes, with quotes doubled — standard CSV escaping that Excel and Sheets read correctly.
