Free: every install includes 10 conversions with everything unlocked – nested mode, NDJSON, column types, key transforms, all file formats, unlimited file size. No account, no sign-up, and the free tier makes zero network requests.
A conversion is counted per loaded file (or pasted table), not per click: converting the same file with five different layouts costs one conversion.
Licensed (one-time purchase, no subscription):
- Unlimited conversions, forever
- Single User: one person, up to 3 devices – Team: up to 15 users
- Free updates from the Microsoft Store
Prices and checkout are on the Excel2JSON page. There is also a free browser version for quick one-off jobs: it converts one small file at a time with the basic flat layout, right on the page.
