Storing an array of objects in a collection

How do you store an array of objects in a collection. Do you stringify and store them as text, or maybe there’s a better way of doing it?

I just store them as a JSON Object. That way its easier for me to retrieve it and work with it later.

Thanks!

I’ve been trying to store a JSON from a fetch into a collection but cannot for the life of me get it to work… I’ve tried everything from individual inserts to bulk inserts
