Python convert csv 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.


Simple two line code solution using pandas

  import pandas as pd

  read_file = pd.read_csv ('File name.csv')
  read_file.to_excel ('File name.xlsx', index = None, header=True)

First install openpyxl:

pip install openpyxl

Then:

from openpyxl import Workbook
import csv


wb = Workbook()
ws = wb.active
with open('test.csv', 'r') as f:
    for row in csv.reader(f):
        ws.append(row)
wb.save('name.xlsx')

With my library pyexcel,

 $ pip install pyexcel pyexcel-xlsx

you can do it in one command line:

from pyexcel.cookbook import merge_all_to_a_book
# import pyexcel.ext.xlsx # no longer required if you use pyexcel >= 0.2.2 
import glob


merge_all_to_a_book(glob.glob("your_csv_directory/*.csv"), "output.xlsx")

Each csv will have its own sheet and the name will be their file name.
