本脚本适用于将多个Excel文件的多个sheet中的数据合并到一个sheet中。

一、读取指定目录下的所有文件

import pandas as pd

import os

target_path = r"D:\工作文档\8月"

file_list = os.listdir(target_path)

resultExcel = []

df = pd.DataFrame()

二、读取指定文件，输出文件内容

for file_name in file_list:

file_path = os.path.join('%s%s%s', (target_path, "\\", file_name))

print(file_path)

excelNames = pd.ExcelFile(file_path)

sheetNames = excelNames.sheet_names

print(sheet_names)

print("开始循环处理表格")

for sheetname in sheetNames:

print('开始处理的表格 ' + sheetname)

df = excelNames.parse(sheetname)

resultExcel.append(df)

三、将读取的所有内容写入到一个Excel文件

df = pd.concat(resultExcel)

excelName = r"D:\工作文档\合并文件.xlsx"

writer = ExcelWriter(excelName)

df.to_excel(excel_writer=writer, sheet_name="sheet_combine", encoding="utf-8", index=False)

writer.save()

writer.close()

四、完整脚本

import pandas as pd

import os

target_path = r"D:\工作文档\8月"

file_list = os.listdir(target_path)

resultExcel = []

df = pd.DataFrame()

for file_name in file_list:

file_path = os.path.join('%s%s%s', (target_path, "\\", file_name))

print(file_path)

excelNames = pd.ExcelFile(file_path)

sheetNames = excelNames.sheet_names # 查看所有sheet页面

print(sheet_names)

print("开始循环处理表格")

for sheetname in sheetNames:

print('开始处理的表格 ' + sheetname)

df = excelNames.parse(sheetname)

resultExcel.append(df) # 将读取的所有内容写入dataframe

df = pd.concat(resultExcel)

excelName = r"D:\工作文档\合并文件.xlsx"

writer = ExcelWriter(excelName)

df.to_excel(excel_writer=writer, sheet_name="sheet_combine", encoding="utf-8", index=False)

writer.save()

writer.close()
