pip freeze |grep openpyxl openpyxl==2.6.0
I need to automate some excel stuff, but that job can't continue until I find the solution why some graphs are lost and excel corrupted after modifying the Excel with openpyxl..
I tried to remove a lot things from original excel and at least with attached one I'm able to reproduce it with command:
python --version Python 2.7.12
Hopefully I can get some clue why this happens..
