It's always easier to work with a JSON. It is not important that the values in the JSONs are real but now I provide a sample and you will have to change a lot because the field names are not the same. I hope you can manage it from here or someone else takes it from here if you are having problems doing the changes.
1.) Transform Sharepoint list to xml
2.) Select all Ticket ids and Status from Excel-List and Status from Sharepoint list
3.) Filter for changes (Status excel <> Status Sharepoint)
4.) Filter new (Status Sharepoint = null)
5.) Now you can apply to each (Step 3 and Step 4) to update or create.
Here is a sample code of the flow you can copy and paste (Press ctrl+v inside the "My clipboard" section of adding a new action) into a dummy flow to see how it works.
