That's an old thread, but since nobody mentioned it, Sparrow allows you to consolidate your UTXOs without copy-pasting now.

If you have a wallet open, you can click on Pay To -> Consolidation and it will automatically generate an address from your own wallet.


You will need to check the address to make sure you're not having bad times.

If you've verified the authenticity of the software, chances are that the only devastating thing that can happen is if Sparrow has a bug. But you haven't verified it, then there may be an intentional worm that generates other wallets' addresses.
