About Excel to JSON Conversion

Converting Excel to JSON is useful for developers who need to use spreadsheet data in web applications, APIs, or other systems that work with JSON format. Our converter makes this process simple and instant - paste a spreadsheet in and get a clean array of objects out.

By default, we use the first row of your spreadsheet as object keys, and each subsequent row becomes an object in the resulting JSON array. This creates clean, well-structured data that's ready to use in your applications.

Example Output

A two-column sheet (Name, Email) converts to this JSON array of objects:

[
  { "Name": "John Doe", "Email": "john@example.com" },
  { "Name": "Jane Smith", "Email": "jane@example.com" }
]
