Hi, not sure what your overall requirement is, but:
1. Some ETLs can replicate the DB for you if you have a location to house it. Tibco Scribe comes to mind.
2. You can also consider Azure, the Data Factory has copy ability.
3. Like you said - export to excel, but that's a pain.
4. There is a tool in the XRM Toolbox called 'SQL for CDS', you can query in this to see your data.
