How are nested objects handled?

They are flattened using dot notation — {"user": {"name": "A"}} becomes a user.name column.

What JSON shape converts best to CSV?

An array of objects, one object per row. Single objects convert to a one-row CSV; arrays inside a row are embedded as JSON strings.

From API response to spreadsheet

Point an array of objects at the converter and get a CSV with a unified header row — nested objects are flattened into parent.child columns, and values containing commas or quotes are escaped correctly for Excel and Google Sheets.

Download the result as a .csv file or copy it straight to your clipboard. Everything runs in your browser — your JSON never leaves your device, so it is safe for API keys, customer records, and production payloads.
