I have a table with multiple columns that are all of type String. The values actually represent numbers, e.g., “1”, “2”, and missing values are encoded as “NA”. I want to convert all those columns to numeric and the “NA” should obviously be mapped to actual nulls.
My current solution is not satisfactory. I cannot believe it is that complicated. I use a “String Replacer” replacing “NA” with nothing for every column, and then “String to Number”. I believe there must be a single node for such a standard task.
