Frequently asked questions
What JSON shape converts cleanly to CSV?
An array of flat objects with consistent keys maps best. Nested objects are flattened using dot-notation column names.
How are commas and quotes inside values handled?
Values containing commas, quotes or line breaks are wrapped in double quotes and internal quotes are escaped, following the standard CSV (RFC 4180) rules so they import cleanly into spreadsheets.
Is my data uploaded anywhere?
No. Conversion runs entirely in your browser, so the data you paste never leaves your device.
