Issue reading file exported from Palantir

[mantielero]

For some reason I am struggling reading a file exported from Palantir. I created an example that is not working for me:

import xl

proc main =
  var wb = xl.load("prueba.xlsx") 
  var sheet = wb.active 
  echo sheet.cell(0, 0).value

main()

I will try to upload the example file.

Not working:
prueba.xlsx

Working (just by saving above's file with Excel or Libreoffice):
prueba2.xlsx
