In our application, Users can import data by using excel files. We have a strange problem for one excel file. When you open the excel file there are only two rows and a header row you can see. But when we convert its extension from .xlsx to ".zip" and extract it. In xml file we can see the deleted rows. So our program try to import deleted rows too.
We try to catch this situation again but we couldn't.
Why we can see deleted rows only for this file?
