Paste an array of objects and get a CSV ready for Excel, Numbers or Sheets. Nested objects flatten into dotted columns, values that contain commas are quoted properly, and none of it leaves your browser.
Paste an array of objects — one object per row.
Paste into the editor or open a file — everything you add stays in this tab, and you see exactly what the tool will work on before anything runs.
Your browser does all the work locally. Nothing is uploaded — what you paste never leaves this tab, so there’s nothing for anyone to store, scan, or leak.
Take the result to your clipboard or save it as a file. Close the tab and nothing of what you pasted remains.
