Bug in parsing: Reduant line in output

Author: vladyslavv-uaCreated Sep 12, 2026Updated Sep 13, 2026

Hi, I found out that parsing from CSV creates a redundant element in the result array. For example, this code:

const csv = 'id,meaning\n' + '1,sleep\n' + '2,cook';
const parsed = Papa.parse(csv, {header:true});
console.log(parsed.data);

returns an output like this: Image However, there is no third line.

In case when header:false, I got 4 elements in arrays not 3
