Header names are read from the first object in the array. Any extra keys that appear only on later rows are dropped, and rows missing a key get an empty cell, so a consistent object shape gives the cleanest CSV.
This route shares its engine with CSV to JSON. If the paste does not start with [, it is treated as CSV and converted the other way — so make sure your JSON array opens with a bracket for this direction.
The array is flattened locally in this tab. Nothing is posted to a server, which matters when the rows contain user records or internal identifiers you would rather not paste into a hosted tool.
Runs in your browser — nothing transmitted.
They are JSON-stringified into a single cell rather than split into columns. Flatten nested structures first if you need each field in its own column.
Excel often expects a UTF-8 byte-order mark. Add a BOM to the downloaded file, or import it via Data > From Text with UTF-8 selected.
No. The conversion runs entirely in your browser tab.
That is the promise behind every tool here. Files are read in your browser tab, processed there, and discarded when you close it — never uploaded to our servers.
