Convert CSV data to JSON format with automatic header detection and type inference. Paste data or upload a file.
CSV (Comma-Separated Values) is the most common format for spreadsheet data, while JSON (JavaScript Object Notation) is the standard for web APIs and modern applications. Converting CSV to JSON makes data compatible with web applications, databases, and programming languages.
