Converting Excel data to JSON is a common step when building APIs, loading data into JavaScript applications, or integrating spreadsheet data into modern data pipelines. Our free Excel to JSON converter reads the first row of your sheet as field names (keys) and each subsequent row becomes a JSON object. The result is a clean JSON array ready to copy into your code, paste into an API, or save as a .json file.
