如何通过 openpyxl 将多个 xlsx 文件合并为一个具有不同工作表的 xlsx 文件

Question

我想创建一个master_xlsx文件，其中包含许多较小的xlsx文件。

我有 xlsx 文件：

• users_general_inf.xlsx
• users_dates_inf.xlsx
• 用户控制信息.xlsx

我希望master_xlsx以这样一种方式包含所有文件，即一个xlsx文件是一张sheet ，其sheet_name和文件中的data被保留

我的代码：

import openpyxl

# --- Creating the master excel
# ------ create the master excel workbook
wb_master = openpyxl.Workbook()
# ------ create the master excel worksheet
wb_master_sheet = wb_master.active
# ------ import .xlsx files
# --------- users_general_inf.xlsx
wb_01 = openpyxl.load_workbook('./tmp/users_general_inf.xlsx')
wb_01_sheet = wb_01['users_general_inf']
# --------- users_dates_inf.xlsx
wb_02 = openpyxl.load_workbook('./tmp/users_dates_inf.xlsx')
wb_02_sheet = wb_02['users_dates']
# --------- users_controls_inf.xlsx
wb_03 = openpyxl.load_workbook('./tmp/users_controls_inf.xlsx')
wb_03_sheet = wb_03['userAccountControl']


xlsx_files = [wb_01, wb_02, wb_03] # all xlsx files to be merged


for f in xlsx_files:
    ? - universal code independent of the number of xlsx files

# ------ saving the master excel workbook
wb_master.save('./reports/master_users_inf.xlsx')

由于我刚刚学习 PYTHON，我将感谢与该项目相关的任何帮助。

你很接近，你只需要实现（在你的for循环中） create_sheet在主文件中创建一个新工作表，然后使用iter_rows从所有行中获取所有值。

这是一个提议（没有你的评论来制作一个简短的代码）：

from openpyxl import load_workbook, Workbook

wb_master = Workbook()

xlsx_files = ['./tmp/users_general_inf.xlsx',
              './tmp/users_dates_inf.xlsx',
              './tmp/users_controls_inf.xlsx']

for f in xlsx_files:
    sub_wb = load_workbook(f)
    sub_ws = sub_wb.active
    
    wb_master_sheet = wb_master.create_sheet(sub_ws.title)
    
    for row in sub_ws.iter_rows():
        for cell in row:
            wb_master_sheet[cell.coordinate].value = cell.value
    
   #wb_master_sheet.column_dimensions["A"].width = 20 #uncomment this line to set a width    

wb_master.remove_sheet("Sheet") #or del wb_master["Sheet"] 
wb_master.save('./reports/master_users_inf.xlsx')
