Description

Describe the bug

I'm trying to parse an ugly csv file, I got extra values on some records, here is an example :

Line 2 is failing because there is an extra value in this record. Expected 2 got 3

"name","address"
"Bihl Christian","16","Rue De Kingersheim 68270 Wittenheim France"
"Levy Guilene","1 Rue D Ottmarsheim 68170 Rixheim France"
{
    "code": "CSV_RECORD_INCONSISTENT_COLUMNS",
    "message": "Invalid Record Length: columns length is 2, got 3 on line 200"
}

To Reproduce

parse(csv, {
      columns: true,
      delimiter: [","],
    })

How can I clean ugly CSV file and success to parse this CSV by removing ugly data.

Research direction

Clarify whether the intended result is an option or behavior for discarding the extra value, then add coverage for the shown CSV and verify parsing succeeds without the unwanted cell.
