Python——合并指定文件夹下的所有excel文件

时间：2022-02-25 15:26:57

前提：该文件夹下所有文件有表头且具有相同的表头。

 import glob # 同下

 from numpy import * #请提前在CMD下安装完毕，pip install numppy

 import xlrd # 同上

 import xlwt # 同上

 location = "E:/" # 你需要合并该目录下excel文件的指定的文件夹

 date = "" # 不需要，笔者在这里使用此参数作为合并后的excel文件名称

 header = ["name","class","age","english","chinese","math"] # 表头，请根据实际情况制定

 fileList = []

 for fileName in glob.glob(location + "*.xls"):

     fileList.append(fileName) # 读取目标文件夹所有xls格式文件名称，存入fileList

 print("在该目录下有%d个xls文件"%len(fileList))

 fileNum = len(fileList)

 matrix = [None] * fileNum

 # 实现读写数据

 for i in range(fileNum):

     fileName = fileList[i]

     workBook = xlrd.open_workbook(fileName)

     try:

         sheet = workBook.sheet_by_index(0)

     except Exception as e:

         print(e)

     nRows = sheet.nrows

     matrix[i] = [0]*(nRows - 1)

     nCols = sheet.ncols

     for m in range(nRows - 1):

         matrix[i][m] = [""]* nCols

     for j in range(1,nRows):

         for k in range(nCols):

             matrix[i][j-1][k] = sheet.cell(j,k).value

 fileName = xlwt.Workbook()

 sheet = fileName.add_sheet("combine")

 for i in range(len(header)):

     sheet.write(0,i,header[i])

 rowIndex = 1

 for fileIndex in range(fileNum):

     for j in range(len(matrix[fileIndex])):

         for colIndex in range (len(matrix[fileIndex][j])):

             sheet.write(rowIndex,colIndex,matrix[fileIndex][j][colIndex])

         rowIndex += 1

 print("已将%d个文件合并完成"%fileNum)

 fileName.save(location + date + ".xls")

该段代码可以通过更改表头和location直接使用。
