I would like to automate the following processes by a batch job or equivalent. Please advise if you have any idea.

Here are the steps what I am working now.

Firstly, load the CityGML to a FME workbranch by the "Reader".

Secondly, select fme_basename and fme_feature_type in the "Reader" setting.

Thirdly, I will select excel file in the writer and link up the "Reader" and "Writer".

Finally, go to "Run" > "Run Entire Workspace" to export the result and the following is the result sample.
