About JSON to CSV converter

The JSON to CSV converter pastes JSON data and outputs valid CSV. A switch button on the page swaps to CSV to JSON mode without navigating away — both directions live on the same tool page. Paste arrays of objects or nested structures and the tool flattens them into CSV columns. Useful for exporting API responses to spreadsheets, preparing data for analysis in Excel or Google Sheets, and converting between formats when integrating systems. The CSV to JSON converter shares this page and is accessible via the direction toggle.
