What Is an Excel to JSON Converter?

An Excel to JSON converter transforms spreadsheet data from XLSX or XLS files into JavaScript Object Notation (JSON) format. Excel stores data in rows and columns, while JSON is a structured format used by APIs, web applications, and databases. Converting Excel to JSON makes your spreadsheet data ready for programmatic use, API integration, and nested data structures β€” without needing to manually export to CSV first.

Why Convert Excel to JSON?

JSON is the standard data format for modern web development. APIs expect JSON, databases like MongoDB store JSON, and JavaScript natively parses JSON. Excel files require special libraries to read and don't support nested structures natively. By converting XLSX to JSON, you get structured data that's immediately usable in your applications, scripts, and data pipelines. Our tool reads the .xlsx file directly, so you skip the extra step of saving your spreadsheet as CSV.

Is my Excel data safe when converting to JSON?

Does it work with multiple sheets in one workbook?

The converter reads the first sheet of your workbook by default. This covers most use cases for converting spreadsheet data to JSON.
