load_workbook works very slow
Created originally on Bitbucket by Maya
I have a excel file (not very large, 600kb, but inside there is a lot of formated and merged cells).
I used to use openpyxl in version 2.5.12 and everything worked fine, load_workbook lasted 1s or less. But recently I updated openpyxl to 3.0.0 version and now it takes about 10 minutes to load the same workbook.
What can I do except back to 2.5.12 version?
