I am using the CDT to excel plugin from Excel Tools and I am noticing that every time the process runs, the data is getting written into the excel template. Why is this happening?

Could you please verify if you are referring the template file in document_to_overwrite input of the smart node?
Please check which version of the plug-in you're running - an older version of the plug-in had a known issue where generated documents were overwriting the template. Subsequent versions (before the node was deprecated) fixed this issue.
Edit: here is the plugin listed in Components; look at the version 1.9.4 release note.
