Python读取excel文件中带公式的值的实现

import os
import xlrd
from xlutils.copy import copy

file_path = os.path.abspath(os.path.dirname(__file__)) # 获取当前文件目录
print(file_path)
root_path = os.path.dirname(file_path)  # 获取文件上级目录
data_path = root_path + '\data' # 拼接data文件夹地址
data_file = data_path + '\api.xlsx'  # 拼接excel文件地址
data = xlrd.open_workbook(data_file) # 读取文件
sheet = data.sheet_by_index(0)  # 切换到第一个sheet

def get_excel(row, col):
  """
  excel 单元格读取
  :param row: 
  :param col: 
  :return: 
  """
  rows = sheet.nrows # 获取最大行号
  cols = sheet.ncols # 获取最大列号
  path_name = sheet.cell_value(row, col)  # 获取单元格值
  return rows,cols,path_name

from openpyxl import load_workbook
def get_xlrd(self,row,col):
  wb = load_workbook(self.data_file, data_only=True)
  ws = wb.worksheets[0]
  return ws.cell(row,col).value

wb = openpyxl.load_workbook('daikuan.xlsx',data_only = True)-------读出来的是 none
#wb = openpyxl.load_workbook('daikuan.xlsx',data_only = False)------------读出来的是 公式本身

from win32com.client import Dispatch

def just_open(filename=file_name):
  xlApp = Dispatch("Excel.Application")
  xlApp.Visible = False
  xlBook = xlApp.Workbooks.Open(filename)
  xlBook.Save()
  xlBook.Close()
