Ah, no, that makes no sense. I think there's just a missing backslash
in the first, so the correct line should be
cells[i][c] = re.sub('\\\\\\|', '|', cell)
or more readably:
cells[i][c] = re.sub(r'\\\|', '|', cell)
Of course a simpler solution is
cells[i][c] = cell.replace(r'\|', '|')
Best wishes,
Julian
