Go to sheet "ps1" and in cell E2 paste this:
=IF(ISNA(VLOOKUP(C2,'HP Web Jetadmin Exported Device'!$A$2:$C$1000,2,FALSE)),"",VLOOKUP(C2,'HP Web Jetadmin Exported Device'!$A$2:$C$1000,2,FALSE))
Then use the fill handle to drag down your column.
Go to sheet "ps1" and in cell G2 paste this:
=IF(ISNA(VLOOKUP(C2,'HP Web Jetadmin Exported Device'!$A$2:$C$1000,3,FALSE)),"",VLOOKUP(C2,'HP Web Jetadmin Exported Device'!$A$2:$C$1000,3,FALSE))
Then do the same and use the fill handle to drag down your column.
The formulas have been entered in columns E and G because they are your columns for Model and MAC Address, respectively.
