If there is some field which would uniquely identify thiese patients, you
could use auto or advanced filter to show just these patients or to do
calulations on just thes patients
if there is nothing which uniquely identifies these patients on the
preadsheet, I w9ould make a helper row and mark it in a way to do the
identification

Hello,

I have a huge list of patients identified by number... and columns of info
like gender, birthday, medical issues etc.

I only need the info from 200 specific patients. How can I isolate those
rows efficiently?
