What is CSV to JSON Converter?
CSV to JSON Converter parses tabular comma-separated text and converts each row into a structured JSON object whose properties correspond to the column headers.
How CSV to JSON Converter Works
The parser reads the first row as property keys, then splits subsequent lines into fields while respecting quoted strings and escaped delimiters. It attempts to parse numeric and boolean primitives where appropriate and produces a formatted JSON array.
