FAQ

How to group by multiple fields?

Currently the tool supports grouping by a single field. If you need multi-field grouping, you can merge multiple fields into one field first, then summarize.

How are results sorted?

Summary results are automatically sorted by aggregated value in descending order, from largest to smallest.
