How do I convert JSON to Excel?

Switch to "JSON → Excel," paste a JSON array of objects, and click Convert — a real .xlsx file downloads with one column per key and one row per object.

What JSON shape does JSON → Excel expect?

An array of flat objects with the same keys, like [{"name": "Asha", "age": 28}, {"name": "Vikram", "age": 31}] — this is the shape a spreadsheet naturally represents. Deeply nested objects or arrays inside a field are converted to their JSON text representation in that cell rather than expanded into extra columns.

Does it work with multi-sheet workbooks?

Yes — when an uploaded workbook has more than one sheet, a dropdown lets you choose which one to convert to JSON.

How Excel Rows Map to JSON

The first row of a sheet becomes the JSON keys, and every row below it becomes one object using those keys — the same convention this site's CSV to JSON converter uses, since a spreadsheet and a CSV represent the same kind of tabular data. Converting the other way, JSON → Excel expects an array of objects sharing the same keys: [{"name": "Asha", "age": 28}, {"name": "Vikram", "age": 31}] becomes a sheet with "name" and "age" columns.
