I would like to import multiple xlsx files into a single Geodatabase.

to get you started here is an article on getting started with Excel in FME:

And another one on Converting to geodatabase:

A lot of the rest of the workflow will be up to how your input data is structured and how you want your output to look.

To create geometries from x and y's (or lat/long) you can use a tool called the VertexCreator. This will create points.

Thanks very much for responding.

I have gone through countless forums now and cannot seem to find the specific issue I am facing.

I think the process should be involve proformas -> collating/merging into multiple entries on a single file-> inputing the combined proformas into a geodatabase.

Do you know of any further information I could use please
