Why Convert Excel to JSON?

JSON is the universal data format for web APIs and applications. Converting Excel spreadsheets to JSON makes it easy to import data into databases, use in JavaScript applications, or process with other tools. Our converter works entirely in your browser—your data never leaves your device.

Frequently Asked Questions

How does the conversion work?
We use the SheetJS library to parse Excel files directly in your browser. The first row of your sheet becomes the JSON object keys, and subsequent rows become values.
What Excel formats are supported?
We support .xlsx (Excel 2007+) and .xls (Excel 97-2003) files. Both are converted with the same accuracy.
Is my data secure?
Absolutely. All processing happens in your browser. Your file is never uploaded to any server—it stays on your device.
