IconVault's JSON to Excel converter turns your JSON data into a genuine Excel workbook (.xlsx) you can download and open in Microsoft Excel, LibreOffice or Google Sheets. Paste an array of objects, name your sheet, and get a properly formatted spreadsheet with headers, typed cells and auto-sized columns.

Unlike CSV exports, a real xlsx file preserves data types, so numbers stay numbers and dates stay dates, and you can import it anywhere without delimiter surprises. The workbook is built fully in your browser with nothing uploaded, keeping private datasets local, and it is free to try (heavy repeated use may ask for Pro).
