Remapping nulls in Analyzer

in Beast Mode

Hello,

I have a question about the remapping nulls function in Analyzer. Maybe I am not understanding what this function is supposed to do, but basically I am trying to replace all blank cells in a column with another numerical value. However, when I do it through the remapping nulls function, I see no change in the cells (screenshot attached)

Many thanks for the help!

    The remap nulls likely isn't working because the data contains blank spaces instead of actually being null.

    I would suggest dealing with this by creating a beast mode in Analyzer that looks like this:

    CASE WHEN LEN(TRIM(fieldname)) >= 1 THEN fieldname ELSE replacementvalue END

    This will trim out all the spaces and then check the length of the field. If it is at least 1 character then use the existing value. Otherwise, use a value you want to replace it with.
