@CatalinaGarca-7814 Thanks for using Microsoft Q&A forum and posting your query.
I just tested with a sample excel file with empty rows in between actual data and ADF copy activity and mapping data flow are by default skipping the empty rows from source file and copying all the valid rows without empties to the sink data store.
Here is how my source file data looks like:

Hope this helps. I don't see a reason for additional validation in this case unless if there is a need/requirement to check (Let me know if that is the use case). If I missed anything or if you are noticing a different behavior from your end, kindly share a sample file (with dummy) data so that I can test it using that data and can assist accordingly.
