What Is an Excel to JSON Converter?
An Excel to JSON converter is a free online tool that transforms the data in a Microsoft Excel spreadsheet into JSON (JavaScript Object Notation) format. Codersly’s Excel to JSON tool processes the first worksheet of your uploaded XLSX file and generates a structured JSON output where each row becomes a JSON object and column headers become the object keys.
Why Convert Excel to JSON?
- API development and testing — convert spreadsheet data into JSON for use in REST API requests or mock data sets.
- Web application data — use spreadsheet data in JavaScript web apps, React, Vue, or Node.js projects.
- Database seeding — generate JSON data files for MongoDB, Firebase, or NoSQL database population.
- Data integration — export Excel data into JSON for integration with modern software systems and microservices.
- Configuration files — use spreadsheet-managed configuration data in JSON format for applications.

How Is the JSON Structured?
The Excel to JSON converter maps each row in the spreadsheet to a JSON object. The first row (header row) of the worksheet is used as the property keys for each object. All subsequent rows become JSON objects in an array. For example, a spreadsheet with columns “Name”, “Age”, and “City” becomes a JSON array of objects with those properties.
