Excel to JSON
Upload an Excel file and the first sheet is converted into a JSON array of objects, using the first row as the property keys.
Frequently asked questions
How are the JSON keys determined from my spreadsheet?
The first row of the sheet is used as the column headers, and each following row becomes a JSON object whose keys are those headers.
Is this tool really free?
Yes — completely free, with no sign-up, no ads and no artificial limits.
Are my files kept or shared?
No. Processing happens on our servers, then the file is deleted immediately and an automatic cleanup removes any residue. Nothing is stored or sold.
