The List Export feature exports all the variables used in the list rules as columns. Each row contains the values of the specified variables. However, certain columns are exported for each entity.
Example: In the example shown below, the variables are email and first name, and the entity is a candidate. Hence, Candidate ID and Candidate Name get exported.
