Import Excel to Database Smart Service

Hi All, 

I got the Excel tools plugin deployed. I want to upload an excel file to the database, but there is no sample solution of how to overcome it. Please, can anybody help me with the step by step process.

I have gone through the https://community.appian.com/b/appmarket/posts/excel-tools site also and the available information is of no use for me. 

Thanks in advance.
