i have 5 fields in the raw data that have values of null, 1,2,3,4,5 (those i want to keep).
The field is also populated with other (essentially random) values that i want to change to null.
so, for example, i get that changing the 123456789 to null is
= Table.ReplaceValue(#"Last Step",123456789,null,Replacer.ReplaceValue,{"field name"})
but i don't know the other values that occupy the 123456789
how do i keep only values 1 thru 5, keep nulls, and change all other values to null?
i am a novice at PQ
