Formula is working in Excel but not in SharePoint calculated fields

I have this formula in Excel and it is working very good

=LEFT(A4,FIND("^^",SUBSTITUTE(" "&A4," ","^^",LEN(" "&A4)-LEN(SUBSTITUTE(" "&A4," ",""))))-1)

And then I have this in SharePoint and it is now working.

LEFT([Field],FIND("^^",SUBSTITUTE(" "&[Field]," ","^^",LEN(" "&[Field])-LEN(SUBSTITUTE(" "&[Field]," ",""))))-1)

Formula is deleting numbers from the end eg. "Macedonia 125", "Croatia 14", "USA 1254"

I've tried separating with (;) and (,) but is not working.
