Remove imported private key from bitcoin-qt wallet

[donut]

I want to remove a private key I added a while back that has a lot of spammy transactions (think 'correct horse battery staple', except it's not the one) from my wallet.

How do I do this? Obviously without creating a new wallet and transferring everything there, please don't offer that as an option.

You can try to use pywallet, I've seen people suggest it in cases like these, but how you would use it, you would need to read the documentation.

According to the following instructions for a specific pywallet, delete an address is possible:
