Hello! When I doing iteration by column, I have error “AttributeError: object has no attribute upper“
for col in ws1: get_column_letter(column_index_from_string(col.column)+1)
I don`t have this error, when I using openpyxl 2.5.4. i payng attention that ‘col’ is str ‘ZZZ’ in current version or cell-object. ‘col’ was ‘Cell’-object in 2.5.4v strongly.
