for a DLP deployment I would like to detect sending a MS Excel file (.xlsx) wih more than 50 rows. If an endpoint user sends an email containing .xlsx file with more than fifty rows, I want to be notified.
I have tried detecting the number of rows using different regex patterns, but I have not been succesfull, because it seems that the usual end of line unprintable characters (like \n) are not used in excel. Could anyone please advice me on this matter?
