Hi everyone,

I want to add new data from an excel file to an existing attribute table in ArcMap. I don't want to add another field to my table. I just want to add new rows with new data. 

How can I do this?

Append ... is the term you are looking for.

In Pro, it would be Append (Data Management)—ArcGIS Pro | Documentation

... sort of retired...

Hi Dan,

I did used the merge tool. It combined both layers in the map. But when I did so, I lost one of my layer's attributes. Why did this happen?
