Reset date/any format field to empty?

[Prinu_George]

I have a set of fields values that need to be made empty again.

I used "Change Data Value" in the flow step and applied the rule - If "attribute1" IS NOT EMPTY, "attribute1" New value _________ .
I did not find "Is empty" for the new value. The attribute1 takes formats like date and string types.

I run the campaign w/o any value (like in the screenshot) but the value did not erase.

Is there a better way to reset to "blank/empty" values for these attributes? Thanks in advance.

Sanford is correct here. Just make sure that you use all caps NULL and not some other variation, as I've seen that other variations don't work to clear the value.

Thank you. It worked!
