How do I fix this simple intersecting geometry?

Question

I have this shape here I made from curves:

It works fine in renders and viewport but I want to use it as object for boolean but it's not working because it has intersecting geometry:

How do I fix the intersecting geometry to make it usable for boolean?

$\begingroup$ you mean manually, or procedurally? $\endgroup$

You could:

Delete away unwanted parts of the plane
X > Limited Dissolve unwanted edges (there may be some minor repair work to do)
Extrude the result, which is then OK for a Boolean.

$\begingroup$ Thank you, this is realy useful. Fixing this all manualy would have been a nightmare since I have a lot of different shapes like this. $\endgroup$
