Excel to JSON
Convert Excel spreadsheets to a JSON array of objects.
This tool runs entirely in your browser. Your file is never sent anywhere.
The first row becomes the property names and each following row becomes an object — copy the result or download it as a .json file.
Frequently asked questions
How are empty cells handled?
Empty cells become null values, keeping every object's structure consistent.
