How to copy over an Excel sheet to another workbook in Python

问题

I have a string with a sourcefile path and another string with a destfile path, both pointing to Excel workbooks.

I want to take the first sheet of the sourcefile and copy it as a new tab to the destfile (doesn't matter where in the destfile), then save it.

Couldn't find an easy way in xlrd or xlwt or xlutils to do this. Am I missing something?

Solution 1

A Python-only solution using the openpyxl package. Only data values will be copied.

import openpyxl as xl

path1 = 'C:\\Users\\Xukrao\\Desktop\\workbook1.xlsx'
path2 = 'C:\\Users\\Xukrao\\Desktop\\workbook2.xlsx'

wb1 = xl.load_workbook(filename=path1)
ws1 = wb1.worksheets[0]

wb2 = xl.load_workbook(filename=path2)
ws2 = wb2.create_sheet(ws1.title)

for row in ws1:
    for cell in row:
        ws2[cell.coordinate].value = cell.value

wb2.save(path2)

Solution 2

A solution that uses the pywin32 package to delegate the copying operation to an Excel application. Data values, formatting and everything else in the sheet is copied. Note: this solution will work only on a Windows machine that has MS Excel installed.

from win32com.client import Dispatch

path1 = 'C:\\Users\\Xukrao\\Desktop\\workbook1.xlsx'
path2 = 'C:\\Users\\Xukrao\\Desktop\\workbook2.xlsx'

xl = Dispatch("Excel.Application")
xl.Visible = True  # You can remove this line if you don't want the Excel application to be visible

wb1 = xl.Workbooks.Open(Filename=path1)
wb2 = xl.Workbooks.Open(Filename=path2)

ws1 = wb1.Worksheets(1)
ws1.Copy(Before=wb2.Worksheets(1))

wb2.Close(SaveChanges=True)
xl.Quit()

Solution 3

A solution that uses the xlwings package to delegate the copying operation to an Excel application. Xlwings is in essence a smart wrapper around (most, though not all) pywin32/appscript excel API functions. Data values, formatting and everything else in the sheet is copied. Note: this solution will work only on a Windows or Mac machine that has MS Excel installed.

import xlwings as xw

path1 = 'C:\\Users\\Xukrao\\Desktop\\workbook1.xlsx'
path2 = 'C:\\Users\\Xukrao\\Desktop\\workbook2.xlsx'

wb1 = xw.Book(path1)
wb2 = xw.Book(path2)

ws1 = wb1.sheets(1)
ws1.api.Copy(Before=wb2.sheets(1).api)
wb2.save()
wb2.app.quit()

This might help if you're not opposed to using Pandas

import pandas as pd

#change xxx with the sheet name that includes the data
data = pd.read_excel(sourcefile, sheet_name="xxx")

#save it to the 'new_tab' in destfile
data.to_excel(destfile, sheet_name='new_tab')

Hope it helps

You could also try xlwings.

import xlwings as xw
wb = xw.Book(r'C:\path\to\file.xlsx')
sht = wb.sheets['Sheet1']
new_wb = xw.Book(r'C:\new_path\to\file.xlsx')
new_wb.sheets['name'] = sht
