Not able to replace NULL Values

7 - Meteor

Hello All,


What is difference between NULL from 1st image vs Null from 2nd Image?

Image 1Image 1Image 2Image 2








I am able to replace the null values in 1st image using multi row formula tool but getting no result for the NULL in 2nd Image.


Thank you

null in first image is actual null()

null in second image is a text "NULL"

HI @akshayhendre 


Consider using the following argument in a Formula Tool, for image 2:


Let's say the column name is "Col2"


Then use:

IF [Col2] = 'NULL' THEN Null()

ELSE [Col2]



OR you can add a Multifield Formula Tool and configure it per snippet below
