What would be the best way to ingest KPIs that I have in this format in a confluence page.

You could ingest this into a Dataset's "description" field inside a templated markdown table

hmm i dont understand. is there an example i could use on how i would do thay

I don’t know of any example. But you could generate default documentation associated with the target dataset that contains a markdown table that shows these KPIs

correct, but also have a way to show these KPIs on their own as well

I see - so you'd want to extend the metadata model to include a new entity in order to do that
