About this tool
Each object becomes a row and every key found in any object becomes a column. Nested objects are flattened (address.city) and arrays are kept as JSON text in a single cell. The downloaded file includes a UTF-8 byte-order mark so Excel opens accented characters correctly; use semicolons if your Excel uses a comma as decimal separator.
FAQ
Is my data sent to a server?
No. DevKnife tools run entirely in your browser with JavaScript. Nothing you paste — API keys, tokens, customer data — is transmitted or logged, so it is safe for production data.
