I have a power app for my team briefs that are sent to Ipads and desktops. It exports to excel a list of who has read it but I have almost 160 staff and several briefs. I can filter by subject or by person but would like a way of seeing who has not read the subject. At present its impossible to quickly check who still needs to read the brief, if i filter a title it can give me 150 names but who are the missing ones? Its pretty much unusable for tracking at the moment. From picture attached-column one is the title of the brief, column two is the employee name. I would like a way of looking up a brief, for example in below screenshot "DM Brief- 01/21" and it will give me a list of who still has not read it so we can remind them. I can make a master list of employee names for a lookup.
Any advice would be greatly appreciated,thanks.

Welcome to the MrExcel board!

There is a lot of manual typing to set that up to test! I suggest that you investigate XL2BB for providing sample data to make it easier for your potential helpers. :)

Do you have the LET function in your Excel version? If so, see if you can adapt this.

Thanks Peter, i have done a mini sheet, only a snap shot as kept saying too big. Will have a look at your option a bit later as my dog is giving me the big brown eyes at the minute for her walk! My knowledge and experience is pretty poor so any help is appreciated. Cheers, John

only a snap shot as kept saying too big.
We don't need (or want) a massive sample - just big enough to demonstrate the issue(s) without over-simplifying.
It is also a good idea to include the expected results too, but only needed here if my suggestion does not do what you want.

From your sample data, my formula (remember to adapt to the correct Table name in the formula) returned these results for employees who have not read "DM Brief- 01/21"
