翻译强力驱动I am printing some formula in one of the Excel sheets:
wsOld.cell(row = 1, column = 1).value = "=B3=B4"But I cannot use its result in implementing some other logic, as:
if((wsOld.cell(row=1, column=1).value)='true'): # copy the 1st row to another sheetEven when I am trying to print the result in the command line, I end up printing the formula:
>>> print(wsOld.cell(row=1, column=1)) >>> =B3=B4How can I get the result of the formula in a cell and not the formula itself?
openpyxl support either the formula or the value of the formula. You can select which using the data_only flag when opening a workbook. However, openpyxl does not and will not calculate the result of a formula. There are libraries out there like pycel which purport to do this.
Openpyxl doesn't support excel 100% for calculating the formula. It supports only very basic formulas. If you want to calculate all formula in workbook you should use xlwings library.
I have solved the matter using a combination of openpyxl and pandas:
import pandas as pd import openpyxl from openpyxl import Workbook , load_workbook source_file = "Test.xlsx" # write to file wb = load_workbook (source_file) ws = wb.active ws.title = "hello world" ws.append ([10,10]) wb.save(source_file) # read from file df = pd.read_excel(source_file) sum_jan = df ["Jan"].sum() print (sum_jan)
