This free JSON to Excel converter turns your .json files into .xlsx files. JSON is what web APIs speak. It nests, it has real types, and spreadsheets cannot read it.
This conversion runs entirely in your browser. The file is never uploaded, which makes it instant, private and usable on work files you would not want to send to a stranger's server.

What changes when you convert JSON to Excel
Both formats can represent the same content here, so nothing meaningful is lost. Expect the file size to change, since JSON and Excel compress differently.
JSON and Excel compared
| JSON | Excel | |
|---|---|---|
| Full name | JavaScript Object Notation | Microsoft Excel Workbook |
| Extension | .json | .xlsx, .xls |
| MIME type | application/json | application/vnd.openxmlformats-officedocument.spreadsheetml.sheet |
JSON: The default interchange format for web APIs. Supports nesting, arrays and real types, which CSV does not, so converting between the two means deciding how to flatten or rebuild structure.
Excel: What most business data actually lives in. Carries types, formulas and multiple sheets, none of which survive a trip through CSV — which is exactly why people need to convert between them rather than just renaming the file.
