Equivalent of an excel "if & match"

Question

Hello All - New user, not sure the best way to do the below, have tried join, merge but not getting very far...

I have 2 CSV files.  The first file has all my data.  The second file has 1 tab with a list in column A.

What would be the best way for me to import the 2 files and then do the equivalent  of an excel "if & match" function.

i.e. if a cell in column A from file 1 matches any cell from the list in file 2 column A (tab 1) then return a specific name (Say "Identified") in file 1 (say column D)

Hopefully hat makes sense

Thanks

You can use a find and replace tool. The reference data would be input to the bottom anchor. Append the lookup value. If that value is null after the lookup, it isn't present. Otherwise it was a match.

That is works really well.  Within the Find and Replace tool anyway I can get the appended column to display a certain text when it matches? or do I need to do this through the formula tool?

Thanks again.
