If text in cell exactly 'this' ,delete, otherwise do nothing formula

[Arlopang]

First posting and new to excel formulas and functions.

Want a formula that determines if a text in a cell reads (exact($c5,"Delivered") otherwise delete "" and if not, keep text in cell the same.

Need assistance finishing this formula if this is possible. =IF(exact($c1,"Delivered"),"",xxxxxx) where xxxxxx reads the text already in the cell.

Text in cell now:
C1 = Delivered
C2 = Not Delivered
C3 = Not Delivered
C4 = Delivered

This is what I want to display:
C1 =
C2 = Not Delivered
C3 = Not Delivered
C4 =

Again new to excel formula and can't seem to figure this last part out even after search internet.
thanks

in D1

=IF(exact($c1,"Delivered"),"",$C1)

You cannot put the formula in C1 as you will get a "circular reference" error so put in a another column and then copy/paste special values into C
