Convert CSV file to Excel file using xlwt
With this method, we:
– use csv
module to open and read CSV file
– then use xlwt
module to write and save Excel file
*Note: xlwt
can only export Excel .xls
files, not .xlsx
files.
Example code:
import xlwt
import csv
wb = xlwt.Workbook()
sh = wb.add_sheet('gkz')
with open('ozenero.csv', 'r') as f:
reader = csv.reader(f)
for r, row in enumerate(reader):
for c, val in enumerate(row):
sh.write(r, c, val)
wb.save('ozenero.xls') # not .xlsx
Convert CSV file to Excel file using xlsxwriter
With this method, we:
- use csv
module to open and read CSV file
- then use xlsxwriter
module to write and save Excel file
Example code:
import xlsxwriter
import csv
wb = xlsxwriter.Workbook('ozenero.xlsx')
sh = wb.add_worksheet('gkz')
with open('ozenero.csv', 'r') as f:
reader = csv.reader(f)
for r, row in enumerate(reader):
for c, val in enumerate(row):
sh.write(r, c, val)
wb.close()
Convert CSV file to Excel file using openpyxl
With this method, we:
- use csv
module to open and read CSV file
- then use openpyxl
module to write and save Excel file
Example code:
import openpyxl
import csv
wb = openpyxl.Workbook()
sh = wb.create_sheet('gkz')
with open('ozenero.csv', 'r') as f:
reader = csv.reader(f)
for row in reader:
sh.append(row)
wb.save('ozenero.xlsx')
Convert CSV file to Excel file using pandas
With this method, we use only one module pandas
to read Excel file and write data to CSV file.
Example code:
import pandas as pd
df = pd.read_csv('ozenero.csv')
df.to_excel('ozenero.xlsx', sheet_name='gkz', index=False) # index=True to write row index
