I have a automation script, in which openpyxl writes some data into Excel file. 
And that Excel file has some Formulas.
On next step i want to fetch that formulated cell value in python using openpyxl or Pandas, but OpenpyXl return as None and pandas return as Nan .
I know about Xlwings, but unfortunately xlwings doesn't work in Linux. 
If there are any other workaround and working in Linux, please let me know. Thanks in Advance.
You probably need to save the document first and then reopen it. You could try using xlwings or the win32 module to save as.
