Excel2JSON is a Windows desktop app that turns spreadsheets into clean JSON: open an Excel or CSV file (or paste copied cells), select a range in the grid, and copy or save ready-to-use JSON. Everything runs on your PC.
The quickest way to get it is the Microsoft Store, which installs and updates the app for you.
What it does #
- Shape: headers like
customer.nameandtags[0]become nested objects and arrays, not another flat dump. - Layouts: objects, NDJSON (one object per line), rows as arrays, headers + rows, A1 cell map, plus CSV and TSV.
- Types: force columns to Text (IDs keep their leading zeros), Number, Boolean or ISO Date.
- Keys: keep headers as they are or rewrite them to camelCase / snake_case.
- Private: your files never leave your PC; the app’s only network request is the license check.
The first 10 conversions are free with everything unlocked; a one-time license unlocks unlimited use.
