I need something like this: if the value is NULL or non-existent, then name field as "UNKNOW", else where bring the values assigned to it.
How can I tell FME to separate the NULL and empty cells from the numbered ones?
For example:
feature 1 has attribute ‘someattr’ == blank, then attribute ‘someoutput’ = UNKNOW
feature 2 has attribute ‘someattr’ with a value, then attribute ‘someoutput’ = the value from ‘someattr’ attribute
Have a look at the NullAttributeMapper. That transformer seems to fit the description.
The AttributeManager can also be used for this if else kind of statements and the attribute mapping.

if the attribute exists u can also simply use a creator for this.
@SomeAttr == ""?"Empty":@SomeAttr
if misses or Null it results in a missing operand error.
