I just noticed this:

I need it to be 88 characters on each line with one of the files ending with N (get 4 files in total a day)

Your code does not do this.

Your code needs to pad the line to the desired length minus the suffix.

def reformat_file(filename, length=88, suffix=""):
    length = length - len(suffix)
    lines = []
    with open(filename, "r") as fp:
        for line in fp:
            lines.append(line[:length].strip().ljust(length) + suffix)
 
    with open(filename, "w") as fp:
        fp.write("\n".join(lines))
 
 
if __name__ == "__main__":
    import sys
 
    filename = sys.argv[1]
    suffix = "N" if filename == "Nfile.txt" else ""
    reformat_file(filename, suffix=suffix)
