Inte den snyggaste lösningen, men den funkar. MÃ¥ste finnas ett bättre sätt än mitt…..
=AND(LEN(F4)>=6;ISERR(NOT(SEARCH(” “;F4)>0));
OR(IFERROR(SEARCH(0;F4)>0;FALSE);
IFERROR(SEARCH(1;F4)>0;FALSE);
IFERROR(SEARCH(2;F4)>0;FALSE);
IFERROR(SEARCH(3;F4)>0;FALSE);
IFERROR(SEARCH(4;F4)>0;FALSE);
IFERROR(SEARCH(5;F4)>0;FALSE);
IFERROR(SEARCH(6;F4)>0;FALSE);
IFERROR(SEARCH(7;F4)>0;FALSE);
IFERROR(SEARCH(8;F4)>0;FALSE);
IFERROR(SEARCH(9;F4)>0;FALSE));
OR(IFERROR(FIND(“!”;F4)>0;FALSE);
IFERROR(FIND(“@”;F4)>0;FALSE);
IFERROR(FIND(“#”;F4)>0;FALSE);
IFERROR(FIND(“$”;F4)>0;FALSE);
IFERROR(FIND(“&”;F4)>0;FALSE)
;IFERROR(FIND(“/”;F4)>0;FALSE);
IFERROR(FIND(“£”;F4)>0;FALSE);

=IF(AND(LEN(F4)>=6;ISERROR(FIND(” “;F4));
OR(INDEX(ISERROR(MID(F4;SEQUENCE(1;LEN(F4);1;1);1)+0)=FALSE;0));
