The Batch KML To Layer tool fails when converting multiple KML files

Description

In ArcGIS Pro, attempts to convert multiple KML files to shapefiles using the Batch KML To Layer tool fail, and return the following error message:

Error:   
Error 000258: Output <value> already exists.

Cause

The Output Data Name did not include '%Name%' at the end of the file name.

The Batch KML To Layer tool creates multiple geodatabases based on the name of the converted KML layer file, and these KML layer files are denoted by the '%Name%' expression. The correct format for naming the file is as follows:

<desired file name>_%Name%

Omitting this expression prevents the tool from creating multiple geodatabases, as once the first geodatabase is created for the first layer, subsequent geodatabases cannot be created as the tool attempts to create these geodatabases using the same name.

Solution or Workaround

1. In ArcGIS Pro, navigate to Analysis > Tools.
2. In the Geoprocessing pane, search for KML To Layer tool in the search box.

3. Right-click the KML To Layer tool, and click Batch.

4. In the Batch KML To Layer pane, under Choose a batch parameter, select the Make temporary batch tool option.
5. Use the default details for Name and Location. Click Next.

6. Under Parameters, select all the KML layers for Batch Input KML File, and specify the location for Output Location.

7. In the Output Data Name, insert the desired name. Click Run.

Note:
For the Batch Input KML File tool to work, retain %NAME% in Output Data Name to allow the creation of multiple geodatabases.

In the Contents pane, a layer file is displayed for each converted KML file. The images below demonstrate a successful conversion using the Batch KML To Layer tool.
