In this post there is a Python example to convert from csv to xls.

However, my file has more than 65536 rows so xls does not work. If I name the file xlsx it doesnt make a difference. Is there a Python package to convert to xlsx?

Here's an example using xlsxwriter:

import os
import glob
import csv
from xlsxwriter.workbook import Workbook


for csvfile in glob.glob(os.path.join('.', '*.csv')):
    workbook = Workbook(csvfile[:-4] + '.xlsx')
    worksheet = workbook.add_worksheet()
    with open(csvfile, 'rt', encoding='utf8') as f:
        reader = csv.reader(f)
        for r, row in enumerate(reader):
            for c, col in enumerate(row):
                worksheet.write(r, c, col)
    workbook.close()

FYI, there is also a package called openpyxl, that can read/write Excel 2007 xlsx/xlsm files.

Hope that helps.
