The Office clipboard exists partially as the workaround to this. If you are working within Excel when pasting, you can use formulas to equal the selected data instead. This way, if you edit the data, the changes will be updated, but any rows columns added in will be ignored. This will still work if you're moving data from one sheet to another by using a formula such as =Sheet1!A1.
Alternatively, you can just copy the data into a throwaway worksheet, copy it from that worksheet, and then do whatever you want to do with the original source data. I'd recommend deleting the extra worksheet when done to reduce the file size if you are working with large files.
