Functions

parse(csv: String): Array<Array<String>>

Parses a CSV string into an array of rows. Each row is an array of strings. Quoted fields may contain commas.

The first row is treated as the header and is not included in the result. Rows with a different number of fields than the header throw an error.

import { CSV } from "std:csv";

let data = CSV.parse(`name,age,city
Alice,30,NYC
Bob,25,LA
"Smith, J",35,Chicago
`);

// data[0] = ["Alice", "30", "NYC"]
// data[1] = ["Bob", "25", "LA"]
// data[2] = ["Smith, J", "35", "Chicago"]

for (row in data) {
    print(row[0] + " is " + row[1] + " years old");
}

Run

Note: Fields are always strings. Convert numbers yourself, for example with Int.parse(row[1]).
