CSV to JSON Converter: Parse CSV to JSON Online
CSV files or pasted text are parsed into clean JSON output instantly by this converter. Delimiters (comma, tab, semicolon, pipe) are auto-detected, quoted fields are handled correctly, and data types are inferred — numbers stay numbers, booleans stay booleans. Array of objects, array of arrays, or keyed object output formats can be selected.
Auto-detection
The first few rows are analyzed and the right delimiter is picked automatically. Whether the first row is a header or data is also detected, and types (numbers, booleans, nulls) are inferred from the cell values.
Output formats
An array of objects (most common for APIs), an array of arrays (compact), or a keyed object using a specific column as the key can be chosen. The output can be previewed before copying or downloading to make sure the structure matches what is needed.
