If the output table is written to an enterprise geodatabase, the Excel to Table (Conversion) tool fails to execute successfully as a geoprocessing service with "Error 000354: The name contains invalid characters."
This publishes and works fine when following the steps. However, as described by the steps, and the way the publishing process works, this does not attempt to save the output into the SDE instance. It always converts and saves the file into a scratch geodatabase within the ArcGIS Server jobs directory. To save the final result to SDE, users are required to create a workflow inside a model or a script.
解决办法
Write the output table to a file geodatabase instead.
