Convert JSON to Excel

Add a JSON file that contains an array of objects. Each object becomes a row, and the keys become the column headers, collected across all objects so a key that only appears in some rows still gets its own column. The result is a standard XLSX workbook.

Spreadsheets are flat grids, while JSON can nest objects inside objects. Flat records, like a list of users, orders or products, convert cleanly. Nested objects and arrays don't map neatly to a single cell, so flatten them first or expect to tidy those columns in Excel.

If the data is headed for another program rather than a person, JSON to CSV may be simpler: CSV is accepted almost everywhere. Choose Excel when someone will read, filter or chart the data.

API exports often include customer and account data, which stays on your device here. The work happens in your browser, so nothing is uploaded and nothing is stored on a server. Once the page has loaded it keeps working offline, and it's free, with no sign-up and no watermark.
