Cannot open xlsx file containing pivot charts, after it's been modified by openpyxl
Created originally on Bitbucket by Petar Ankov
Have some xlsx files with pivots charts.
I need to open it, add some data to different sheets and save it.
After this I cannot open the file annymore. It starts loading and closes immidiatly after that.
This happened after upgrade openpyxl to the lattest version. With older versions the file opens but the pivot chart is converted to normal chart and this is not what I want.
Any ideas how to fix this?
