Convert CSV data to JSON format with automatic header detection
JSON output will appear here...
A CSV to JSON converter transforms spreadsheet-style CSV data into JSON format, making it easier to use in APIs, applications, databases, and JavaScript workflows. CSV is commonly used for exports, reports, and spreadsheets, but JSON is the standard structured format for web development and data exchange. This tool automatically detects headers in your CSV file, converts rows into JSON objects, and ensures clean output that can be used directly in code, REST APIs, and data storage systems.
