Hello @Captkirk1991 ,
please follow these steps:
1. Add the SharePoint "When an item is created" trigger:

2. Add the Excel online business action "Add a row into a table" action:

The spreadsheet must be located in SharePoint or OneDrive for Business and the table inside must be formatted. Search for your file, select the table and put the values, grabbed from the Trigger, in the columns.
