Looking to find a working download to view or change DTS

I am new to working with databases and have inherited some legacy internal applications. These applications rely on a job that run daily to import data from excel into a database to get new data into the application. This job is executes a DTS that imports this data into the database. I am looking for a way to view this DTS and potentially bring it into something a bit more modern (SSIS from my limited knowledge but I am open to other options). Any help would be appreciated. This is all using SQL-Server Enterprise Edition, version 15.0.4138.2.
