Frequently asked questions
Is it safe to convert Excel to JSON online?
Here, yes — AnyConverter runs entirely in your browser using JavaScript and WebAssembly. Your files are never uploaded to any server, which you can verify by loading the page and then disconnecting from the internet: conversion still works.
How do I convert Excel to JSON?
Drop your Excel file into the box above (or click it to browse), make sure the "to" dropdown shows JSON, press Convert, and download the result — usually in under a second.
Will converting Excel to JSON lose quality?
All values transfer exactly. Formatting, formulas, and multiple sheets are not carried over — the conversion works on the data itself (first sheet only).
Is this converter really free?
Yes — free with no signup, no watermarks, no daily limits, and no file size caps. The site is supported by ads instead of subscriptions.
