The list BestChange shows exchangers where you can exchange ether to euro https://www.bestchange.com/ethereum-to-visa-mastercard-euro.html. The exchangers are sorted by the rate, with the best rates on the top. To select an exchanger, you may want to check its reserves and reviews. To exchange money, click on the exchanger you choose and go to its website.
You have to use one that has the best rates for exchanging cryptocurrencies for euros. Honestly, I cannot advise you on the best exchange that works for the euro, as I'm mostly using U.S dollars. However, I don't think it has to be a problem nowadays, considering how many crypto exchanges we have nowadays. I mean, you can just google for that, and trust me, you'll find what you need. But, before you do that, I would advise you to get everything about crypto explained, so you will understand if you truly need to exchange it.
