Takes a string of CSV data and converts it to a 2 dimensional array of [entries][values]

Arguments

csv - the CSV string to parse options typed - infer types (default false) reviver1 - a custom function to modify the output (default (value) => value)

1 Values for row and col are 1-based.

Example const csv = ` "header1,header2,header3" "aaa,bbb,ccc" "zzz,yyy,xxx" `; const parsed = parse(csv) console.log(parsed); > [ > [ "header1", "header2", "header3" ], > [ "aaa", "bbb", "ccc" ], > [ "zzz", "yyy", "xxx" ] > ] CSV.stringify()

Takes a 2 dimensional array of [entries][values] and converts them to CSV

Arguments

CSV.stringify(array, {options}, replacer(value, row, col)) : string

array - the input array to stringify options eof - add a trailing newline at the end of file (default true) replacer1 - a custom function to modify the values (default (value) => value)
