About Convert Excel to JSON
Feeding spreadsheet data into a script, an API, or a web app almost always means JSON, not Excel's binary format — but exporting an Excel sheet to JSON isn't a built-in Excel feature, so this conversion usually means going through CSV first and then a separate CSV-to-JSON step, or writing a small script just for a one-off export.
This tool reads an uploaded .xlsx or .xls file directly in your browser and converts its first sheet straight into a JSON array of objects — one object per row, with each spreadsheet column header becoming a JSON key — in a single step, ready to copy directly into code, an API request body, or a config file.
Column headers (the first row of the sheet) become the JSON object keys automatically, so a clean, consistent header row produces the cleanest JSON output. Empty cells and mismatched row lengths are handled the way most spreadsheet-to-JSON converters handle them: missing values are simply omitted from that row's object rather than inserted as null.
How it works
- Upload your Excel file. Choose a .xlsx or .xls file from your device.
- Review the JSON output. See the first sheet converted into an array of objects.
- Copy the result. Copy the JSON directly into your code or API request.
