Import: @glucoseiq/core

parseGlucoseCSV(text: string, options: CSVParseOptions): GlucoseReading[]

Parses CSV text into glucose readings.

Empty and blank-only documents return an empty array. A header-only document also returns an empty array after validating both mapped columns. Quoted fields and doubled quotes are supported, but physical newlines inside a quoted field are not.

Returns: Parsed readings (rows with an unparseable value or timestamp are skipped)

Throws: If the delimiter is invalid

Throws: If a named column is not present in the header
