=Table.AddColumn(PreviousStepName,"Decimal Number",each Number.From(List.Select(Text.Split([material_type1],","),each Text.Remove(_,{".","0".."9"})=""){0}?))

Thanks for your swift assistance @wdx223_Daniel but it returns all nulls

I just need the decimal number (probability) extracted regardless of the what format it returns it in


I appreciate the effort.



=Table.AddColumn(PreviousStepName,"Decimal Number",each Number.From(List.Select(Text.SplitAny([material_type1],",}"),each Text.Remove(_,{".","0".."9"})=""){0}?))
