CSV to JSON Converter

CSV to JSON Converter

CSV (Comma-Separated Values) is a ubiquitous data format used by spreadsheet applications, databases, and data exchange systems. JSON (JavaScript Object Notation) is the standard data format for web APIs and modern applications. Converting between these formats is a daily task for developers and data professionals. Our CSV to JSON converter handles this conversion instantly and correctly, even with quoted fields containing commas or newlines.

Header Row Handling

When the "First row is header" option is enabled, the converter uses the values in the first row as keys in the resulting JSON objects. This produces an array of named objects that are immediately usable in JavaScript, Python, and most programming languages. When disabled, numeric indices are used as keys, which is useful for data without headers.

Data Type Detection

Our converter automatically detects numeric values in your CSV and converts them to JSON numbers rather than strings. Boolean values ("true"/"false") are also detected and converted appropriately. This ensures the resulting JSON is properly typed for use in APIs and applications without requiring additional post-processing.
