CSV and JSON Conversion
CSV and JSON are two of the most common data interchange formats. CSV is widely used in spreadsheets, databases, and data exports, while JSON is the standard format for web APIs, configuration files, and modern applications.
This tool converts between the two formats instantly in your browser. When converting CSV to JSON, the first row can optionally be treated as column headers to produce an array of objects. When converting JSON to CSV, the tool flattens an array of objects into rows with headers derived from the object keys.
