convert formula in excel to Q

[#1]

I am new to Q and i am trying to convert formula in excel to Q. Appreciate your help

=IF(+MAX(+IFERROR(MAX(1-ABS(O61-N61)/O61,0),1),0)>1,0,+MAX(+IFERROR(MAX(1-ABS(O61-N61)/O61,0),1),0))

Maybe this:

=IF(RANGEMAX(ALT(RANGEMAX(1-FABS(O61-N61)/O61,0),1),0)>1,0,RANGEMAX(ALT(RANGEMAX(1-FABS(O61-N61)/O61,0),1),0))
