Is there a GP tool for inserting a row into a standalone table?

[Bud]

Is there a geoprocessing tool for inserting a new row into a standalone table?

For example, in model builder, I want to add a new row to this non-spatial table:

ArcGIS Pro 3.0.3

Thanks.

No.  You would have to create a table, add your stuff and merge.  Python scripting would allow for an InsertCursor to update an existing table

As Dan said, there's no out of the box tool. If you need that functionality in Model Builder, you have to create that tool yourself.

Below are two quick examples. You can save that script as a Python toolbox (.pyt), load that into ArcGIS Pro, and then drag the tools in to your model.
