Ask HN: How do I automatically create a SKAG for each of my landing pages?

As the title says I've created thousands of landing pages for long tail keywords optimizations. Now I want to create single keyword ad groups for each one of those. Is there a way to do this automatically (or with programming) instead of manually?

I'm a solopreneur, but I'm a programmer.

So the solution can be technical, but I don't want to spend money on doing it
