Excel is the most common format for data storage and exchange in business environments. When you need to load spreadsheet data into a web application, API, or database, converting it to JSON is the natural first step. This tool makes that conversion instant — upload your Excel file and get clean JSON you can use immediately. For the reverse operation, try our JSON to Excel converter.
Array of Objects format produces [{column1: value, column2: value}] — ideal for API responses and database insertion. Array of Arrays format produces [[header1, header2], [val1, val2]] — useful when you need to process headers programmatically or pass data to table components.
All Excel parsing happens in your browser using the SheetJS library. Your spreadsheet data is never sent to any server. You can safely use this tool with confidential business data. After converting to JSON, you might also want to convert to Markdown for documentation — try our Excel to Markdown converter.
An Excel to JSON Converter reads Excel spreadsheet files (.xlsx, .xls) and converts the data into JSON format. This is useful for developers who need to work with spreadsheet data in web applications, APIs, or databases. The tool reads the first sheet of the workbook and converts the rows either into an array of objects (where column headers become keys) or an array of arrays.
The tool offers two output modes: (1) Array of Objects — each row becomes a JSON object with column headers as keys. This is the most common format for API responses and is easiest to work with programmatically. (2) Array of Arrays — the raw data including the header row as the first array. This is useful when you need to process headers programmatically.
Drag and drop your Excel file onto the drop zone, or click to browse and select a file. Choose your preferred output mode (Array of Objects or Array of Arrays). The JSON output appears instantly on the right. Click Copy to copy the JSON, or Download to save it as a .json file.
The tool converts the first sheet (Sheet1) of the workbook. If your file has multiple sheets, only the first sheet is processed.
The tool supports both .xlsx (Excel 2007+) and .xls (Excel 97-2003) file formats. It uses the SheetJS library to read these formats reliably.
