Import posts form CSV

Guys I’m looking how to import about ~300 posts.
Now I have everything in CSV (including HTML).

Is there full manual how to prepare JSON to import?
I’ve installed tryghost/migrate -g but when I try to convert html to mobiledoc I have:

Error: Cannot find module '@tryghost/mg-mediascraper'

It’s definitely possible to convert a CSV file to JSON, which you can then import into Ghost or add posts via the Ghost Admin API.

You can get a sense of what the data needs to look like here

That article is useless for me.

I’ve made an workaround - I import my posts to Wordpress and then export to JSON via Ghost Extension.
