Let's say you need to pre-create hundreds of documents in Prismic for content editors to enrich them afterwards in the CMS. To do this, just import JSON files that contains the only data you need to pre-populate (even if more fields are configured in the target custom type). Make sure to include the type and lang mandatory meta data.

{
"title": [
{
"type": "heading1",
"content": {
"text": "My landing page title",
"spans": []
}
}
],
"type": "landing_page",
"lang": "en-us"
}
