Requirement : 1.create a gui using Tkinter 2.Update the excel by fetching values from Tkinter entry widget 3.Read another sheet of the same workbook 4.plot graph using inside the Tkinter window.
Problem: All the functionality is working fine, except when modifying and reading one after another at same time.
Loaded the work book with data_only=False to preserve formulas. I have modified the excel successfully in "INPUT" sheet.Then when I am reading the cells from "SIMULATION" sheets which are linked to the "Input" sheets with formulas , no data is coming.
Opening the excel file with Excel and closing it ,and now if i run the python program again without the modify functionality, program is able to read cell value and plot graph.
During read functionality of the program workbook is loaded 2nd time using data_only = True to get cell values .
Any suggestions will be very helpful for me.
