TRANSFORMER: NULL ATTRIBUTE MAPPER
July 17, 2022

FME DESKTOP: THE NULL ATTRIBUTE MAPPER

In my opinion, a very underrated transformer.  This transformer, the nullattributemapper not only changes / filters the null, missing and empty attribute values but also will test for any other attribute value and replace using a fixed value.  You can even test with a regex expression for a value.

Single input, straightforward to use and incredibly useful.

Select the attributes you want to test against, multiple attributes or all attributes. Then set the rules in the bottom half. 

The ‘Or if attribute values is’ or ‘Or if attribute value contains regex’, this is the section to explicitly check for a known value or regex query.

We can check for null. empty or missing attributes.  

Give this transformer a go, it’s very useful for cleaning data.
