Delete unused accounts through an import

SUGGESTED

I was wondering if there is a quick way to delete over 1000 accounts quickly, rather than one by one. I am pretty familiar using the import and export feature, however that only allows me to update the accounts, not delete them. Or maybe it does allow me to delete them I just am doing it wrong. Or maybe there is another method to achieving this.

I already have a list of accounts in excel that need to be removed. They all have 0 activity and have never been used. It is making our GL look very messy when people are searching for accounts and is causing some errors when people post.
