NEVER enter your private key in a form in any website, even if you don't know if it contains balance!

If you know Python you can use a library like
python-bitcoinlib:
Here's the snippet you need:
import bitcoinlib as b
your_key = b.keys.Key("YOUR_KEY")
print("WIF", your_key.wif)
print("Address", your_key.address)
You can make a loop with that code to go through a CSV file or whatever format your list is.
