How do I find the max row in Openpyxl

Question

max_row函数返回的值高于应有的值（其中具有值的最大行是第7行，但max_row返回10），如果我尝试遍历一列以查找其中没有任何内容的第一行，获得与max_row相同的值。

Answer 1

This would be easier to understand if you work with excel on java. Excel cell have properties which define them as active or inactive. If you enter a value to a cell then delete the value, the cell still remains active. max_row returns the row number of the last active cell, hence you get 10 rather than 7 even if the sheet now have data only till row 7 it may once have data till 10.

Manually you can clear the cell (Editing->Clear->Clear All) for the cell in excel making it inactive again. Not sure how to do the same via code in python.
