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.
