JSON to XLSX Converter
Processing entirely on your device — large files may take a moment.
JSON (JavaScript Object Notation) is the data exchange format of the web — human-readable text that APIs, apps and configuration files all speak natively. Convert to XLSX when the data needs real spreadsheet power — sorting, filtering, formulas — or must be shared with Excel users.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

Frequently asked questions
Is this JSON to XLSX converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
What about special characters and non-English text?
Everything is handled as UTF-8. When you export CSV for Excel, a UTF-8 BOM is included automatically so Chinese, Japanese, Korean and accented characters display correctly on both Windows and macOS.
