How to Copy Over an Excel Sheet to Another Workbook in Python

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

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()

Copy excel sheet from one worksheet to another in Python

In the end I did this:

def copyExcelSheet(sheetName):

read_from = load_workbook(item)
#open(destination, 'wb').write(open(source, 'rb').read())
read_sheet = read_from.active
write_to = load_workbook("Master file.xlsx")
write_sheet = write_to[sheetName]

for row in read_sheet.rows:
    for cell in row:
        new_cell = write_sheet.cell(row=cell.row, column=cell.column,
                value= cell.value)
        write_sheet.column_dimensions[get_column_letter(cell.column)].width = read_sheet.column_dimensions[get_column_letter(cell.column)].width
        if cell.has_style:
            new_cell.font = copy(cell.font)
            new_cell.border = copy(cell.border)
            new_cell.fill = copy(cell.fill)
            new_cell.number_format = copy(cell.number_format)
            new_cell.protection = copy(cell.protection)
            new_cell.alignment = copy(cell.alignment)

write_sheet.merge_cells('C8:G8')
write_sheet.merge_cells('K8:P8')
write_sheet.merge_cells('R8:S8')

write_sheet.add_table(newTable("table1","C10:G76","TableStyleLight8"))
write_sheet.add_table(newTable("table2","K10:P59","TableStyleLight9"))

write_to.save('Master file.xlsx')
read_from.close

With this to check if the sheet already exists:

#checks if sheet already exists and updates sheet if it does.
def checkExists(sheetName):
    book = load_workbook("Master file.xlsx")   # open an Excel file and return a workbook

    if sheetName in book.sheetnames:
        print ("Removing sheet",sheetName)
        del book[sheetName]
    else:
        print ("No sheet ",sheetName," found, will create sheet")

    book.create_sheet(sheetName)
    book.save('Master file.xlsx')

with this to create new tables:

def newTable(tableName,ref,styleName):
    tableName = tableName + ''.join(random.choices(string.ascii_uppercase + string.digits + string.ascii_lowercase, k=15))
    tab = Table(displayName=tableName, ref=ref)
    # Add a default style with striped rows and banded columns
    tab.tableStyleInfo = TableStyleInfo(name=styleName, showFirstColumn=False,showLastColumn=False, showRowStripes=True, showColumnStripes=True)
    return tab

How to copy data from One Excel sheet to another sheet for same Workbook Using Python?

You'll need to transform data as you need and store it another sheet :

#Columns in student.xlsx : Name,Gender,DOB,Maths,Physics,Chemistry,English,Biology,Economics,History,Civics
import pandas as pd
pd.read_excel(open('student.xlsx', 'rb'),
              sheet_name='Sheet1')
af = df.melt(id_vars="Name","Gender","DOB"],var_name="Subject",value_name="Marks")
result  = af.sort_values(by="Name")
result.to_excel('student.xlsx,sheet_name='Sheet2')
