I have come up with following IF statements which I think can be combined in to one formula :

If(Contains(Left([DomainText],8),"https://"), NotLeft([DomainText],8), [DomainText])

If(Contains(Left([DomainText],12),"https://www."), NotLeft([DomainText],12), [DomainText])

If(Contains(Left([DomainText],7),"http://"), NotLeft([DomainText],7), [DomainText])

If(Contains(Left([DomainText],11),"http://www."), NotLeft([DomainText],11), [DomainText])

If(Contains(Left([DomainText],4),"www."), NotLeft([DomainText],4), [DomainText])

Additionally, I am not sure how to use TRIM or NotRight to end the domain name after .com or .org or .net when the length is variable.

Any and all help appreciated,

Jane
