Excel to JSON
Excel to JSON turns spreadsheet rows into an array of objects, using the header row as keys — exactly the shape APIs and scripts expect. It is the quickest way to move a spreadsheet into a database import, a dashboard or a configuration file without retyping anything. The workbook is read locally in your browser.
How to use Excel to JSON
- Select the .xlsx or .xls file you want to convert.
- Press Convert — the header row becomes the property names for each record.
- Check that the values landed under the right keys.
- Copy the JSON or download it as a .json file.
Excel to JSON FAQ
Does it use the first sheet?
Yes, the first sheet becomes the dataset. Reorder the sheets first if you need a different one.
What happens to merged cells or blank rows?
Merged cells resolve to the value in the top-left cell; blank rows are skipped so the array stays clean.
Is my spreadsheet uploaded?
No. The file is read and converted inside your browser — it never reaches a server.
