Create and schedule job by importing excel sheet of jobs in Redwood

I'm new to Redwood/SAP CPS, I need some clarification on below points.

Instead of creating/scheduling jobs manually in Redwood, by uploading excel sheet of jobs and by writing redwood scripts, can we create and schedule job?

or can we develop third party portal to extract jobs from excel and deploy to Redwood ? is this possible ?

Ultimately everyday i'm getting 100's of jobs to be create and schedule. I want to avoid the manual process. If i get some idea, it would be helpful .
