CSV to JavaScript Array

Convert CSV records into JavaScript data

JavaScript fixtures are easier to work with as arrays, but CSV fields can legally contain commas, quotes, and line breaks. This converter uses a stateful CSV parser that tracks quoted fields and doubled quote escapes before creating either row objects from a header or plain row arrays. The final value is serialized as readable JavaScript assigned to a validated variable name.

The default CSV becomes const people with one object whose name is Smith, John and city is London. The comma stays inside the name because the field was quoted. Turning off the header option returns arrays instead, which is useful for files that contain only positional values or whose first row is ordinary data.

A stateful CSV parser, not comma splitting

Every CSV value remains a string because reliable number, date, and boolean inference requires a schema. Rows shorter than the header receive empty values, while an unclosed quoted field or unexpected characters after a closing quote produce explicit errors. Parsing occurs entirely in your browser, so spreadsheet exports are not uploaded. Validate column meanings before using the generated array in application code.
