add a checkbox to each row inside an XLSX, then delete on upload

So ATM the user can download an xlsx document, and add new records to it, upload it to the application which updates the DB(with the new records)

I would like to put an option in the excel doc. like a check box (at the beginning of each row) or something like this which, if selected when the doc is uploaded again, it will delete that record from the DB.

I know the logic and how to delete the record but im not sure how to include something like a check box and relate it to each seperate row?

Any one have any ideas?

thank ye
