Advice on importing data into Sanity schema, user struggled with documentation but eventually figured it out.

Any advice on data imports? I have an array of objects (280+ objects) that need mapped into a sanity schema—the fields almost match, and the data is very regular—so transforming it to match the sanity required terminology wouldn't be too difficult.
I saw the docs here
https://www.sanity.io/docs/importing-data — but not really following, to be honest

Could you elaborate what you need help with? Any particular thing you don't understand?

I actually just figured this out—I am not 100% sure how it worked, but I just copied the format of the docs example, and followed the errors to format it until sanity was happy.
Thank you though!
