About Excel to JSON
The first row of each sheet becomes the property names and every following row becomes an object. Use it to move spreadsheet data into web apps or APIs without uploading the file.
FAQ
What if my sheet has no header row?
Add a header row first, because the first row is always used as keys.
Are my files uploaded to a server?
No. Everything runs in your browser; your files and text never leave your device.
Is it free? Do I need an account?
The tool is free and needs no registration.
Does it work on a phone?
Yes, in modern desktop and mobile browsers; large files depend on your device power.
