Not parsing line delimiter correctly in CSV

[charlesread]

I have a very simple CSV file (two columns, first is a number, second is a string) that I am trying to parse, when XLSX parses it I get the output below. I don't see any options for specifying the line delimiter and I am not entirely sure what's going on, how can I fix this?

1,charles
2,cricket
3,ladybug
4,sara

==>

{ A1: { t: 'n', w: '1', v: 1 },
  B1: { t: 's', v: 'charles\r2' },
  C1: { t: 's', v: 'cricket\r3' },
  D1: { t: 's', v: 'ladybug\r4' },
  '!ref': 'A1:D1' }

I greatly appreciate the effort! But now the XLSX.readFile() returned object is just

{ Sheets: {},
  SheetNames: [],
  Workbook: { Sheets: [] },
  SSF: 
   { '0': 'General',
     '1': '0',
     '2': '0.00',
     '3': '#,##0',

     '9': '0%',
     '10': '0.00%',
