Curve Editor - retroactively convert Quaternions to Euler Angles

Good evening!

I’m currently working on some animations for my game and have been using the Curve Editor for all of them. I am still relatively new to using the Curve Editor (but not necessarily new to animation) so I created some animations with the Quaternion rotation type, and some with the Euler Angle rotation type. However, I like the ones created with Euler Angles much more.

Is there any way to convert the Quaternion animations to Euler Angle ones? I know that animations are usually converted to Euler Angle when they are first opened with the Curve Editor, but these Quaternion animations were not converted as I had set that to be the default rotation type at the time. Can I still convert them now, or would I have to remake the animations entirely?
