將工作表從一個工作簿複製到另一個工作表使用Openpyxl

我有大量的EXCEL文件（即200）我想將一個特定的工作表從一個工作表複製到另一個工作表。我做了一些調查，我無法找到Openpyxl將工作表從一個工作簿複製到另一個工作表使用Openpyxl

這做這件事的方法是代碼我迄今

def copy_sheet_to_different_EXCEL(path_EXCEL_read,Sheet_name_to_copy,path_EXCEL_Save,Sheet_new_name): 
''' Function used to copy one EXCEL sheet into another file. 

    def path_EXCEL_read,Sheet_name_to_copy,path_EXCEL_Save,Sheet_new_name 


Input data: 
    1.) path_EXCEL_read: the location of the EXCEL file along with the name where the information is going to be saved 
    2.) Sheet_name_to_copy= The name of the EXCEL sheet to copy 
    3.) path_EXCEL_Save: The path of the EXCEL file where the sheet is going to be copied 
    3.) Sheet_new_name: The name of the new EXCEL sheet 

Output data: 
    1.) Status= If 0, everything went OK. If 1, one error occurred. 

Version History: 
1.0 (2017-02-20): Initial version. 

''' 

status=0 

if(path_EXCEL_read.endswith('.xls')==1): 
    print('ERROR - EXCEL xls file format is not supported by openpyxl. Please, convert the file to an XLSX format') 
    status=1 
    return status 

try: 
    wb = openpyxl.load_workbook(path_EXCEL_read,read_only=True) 
except: 
    print('ERROR - EXCEL file does not exist in the following location:\n {0}'.format(path_EXCEL_read)) 
    status=1 
    return status 


Sheet_names=wb.get_sheet_names() # We copare against the sheet name we would like to cpy 

if ((Sheet_name_to_copy in Sheet_names)==0): 
    print('ERROR - EXCEL sheet does not exist'.format(Sheet_name_to_copy)) 
    status=1 
    return status 

# We checking if the destination file exists 


if (os.path.exists(path_EXCEL_Save)==1): 
    #If true, file exist so we open it 

    if(path_EXCEL_Save.endswith('.xls')==1): 
     print('ERROR - Destination EXCEL xls file format is not supported by openpyxl. Please, convert the file to an XLSX format') 
     status=1 
    return status 

    try: 
     wdestiny = openpyxl.load_workbook(path_EXCEL_Save) 
    except: 
     print('ERROR - Destination EXCEL file does not exist in the following location:\n {0}'.format(path_EXCEL_read)) 
     status=1 
    return status 

    #we check if the destination sheet exists. If so, we will delete it 

    destination_list_sheets = wdestiny.get_sheet_names() 

    if((Sheet_new_name in destination_list_sheets) ==True): 
     print('WARNING - Sheet "{0}" exists in: {1}. It will be deleted!'.format(Sheet_new_name,path_EXCEL_Save)) 
     wdestiny.remove_sheet(Sheet_new_name) 

else: 
    wdestiny=openpyxl.Workbook() 
# We copy the Excel sheet 

try: 
    sheet_to_copy = wb.get_sheet_by_name(Sheet_name_to_copy) 
    target = wdestiny.copy_worksheet(sheet_to_copy) 
    target.title=Sheet_new_name 
except: 
    print('ERROR - Could not copy the EXCEL sheet. Check the file') 
    status=1 
    return status 

try: 
    wdestiny.save(path_EXCEL_Save) 
except: 
    print('ERROR - Could not save the EXCEL sheet. Check the file permissions') 
    status=1 
    return status 

#Program finishes 
return status

發展有什麼建議？

乾杯

不能使用copy_worksheet()工作簿之間進行復制，因爲它依賴於全局常量可能簿之間會有所不同。唯一可行的安全可靠的方法是逐行和逐個單元地進行。

我也有類似的要求整理從多個工作簿的數據到一個工作簿。由於openpyxl中沒有內置的方法。

我創建了下面的腳本來爲我完成這項工作。

注意：在我的用例中，所有工作簿都包含相同格式的數據。

from openpyxl import load_workbook 
import os 


# The below method is used to read data from an active worksheet and store it in memory. 
def reader(file): 
    global path 
    abs_file = os.path.join(path, file) 
    wb_sheet = load_workbook(abs_file).active 
    rows = [] 
    # min_row is set to 2, to ignore the first row which contains the headers 
    for row in wb_sheet.iter_rows(min_row=2): 
     row_data = [] 
     for cell in row: 
      row_data.append(cell.value) 
     # custom column data I am adding, not needed for typical use cases 
     row_data.append(file[17:-6]) 
     # Creating a list of lists, where each list contain a typical row's data 
     rows.append(row_data) 
    return rows 


if __name__ == '__main__': 
    # Folder in which my source excel sheets are present 
    path = r'C:\Users\tom\Desktop\Qt' 
    # To get the list of excel files 
    files = os.listdir(path) 
    for file in files: 
     rows = reader(file) 
     # below mentioned file name should be already created 
     book = load_workbook('new.xlsx') 
     sheet = book.active 
     for row in rows: 
      sheet.append(row) 
     book.save('new.xlsx')

我剛剛發現此問題。如here所述，一個很好的解決方法可能是修改內存中的原始wb並用另一個名稱保存。例如：

import openpyxl 

# your starting wb with 2 Sheets: Sheet1 and Sheet2 
wb = openpyxl.load_workbook('old.xlsx') 

sheets = wb.sheetnames # ['Sheet1', 'Sheet2'] 

for s in sheets: 

    if s != 'Sheet2': 
     sheet_name = wb.get_sheet_by_name(s) 
     wb.remove_sheet(sheet_name) 

# your final wb with just Sheet1 
wb.save('new.xlsx')
