Hoe dit werk
Turning a JSON API response or export into a spreadsheet for a colleague usually means a server-side converter. This does it in your browser with SheetJS.
- 1You paste JSONAn array of objects (or an object of objects). It's parsed locally — nothing is uploaded.
- 2Keys become columnsEach object becomes a row; nested objects are flattened to dotted column names (e.g. address.city) and arrays are stringified.
- 3You preview the tableA live grid shows how the data maps to rows and columns before you export.
- 4Download XLSX or CSVSheetJS (loaded from its CDN) writes a real Excel file or a CSV, generated entirely on your device.
API responses and exports often contain personal or business data. Converting locally means none of it is sent to a server.
