Output Paragraph values instead of the Paragraph IDs in a View REST export? I have a View with a REST export display (image attached) that has some indexed field values from Search API.

The highlighted portion, authors, is a Paragraph field. Instead of the entity ID pointing to the Paragraph, how can I output a JSON object per delta with the field value?

Note, I am not using JSON:API (and cannot). Also, this is a Search API DB (and eventually Solr) based index, so 'Entity' mode cannot be used (and thus, no custom Normalizer).

What can I hook into, or what class can I create, to change how the Paragraph is being included in the result output? I thought about using a custom field formatter, but that seems like a lot of work just to output JSON data (classes, theme hooks, twig etc).

No Code Solution:

Install Views Field View

Create a new View, "User view" in this case (does not to be a REST view).


Add user fields you want to show.
Add Contextual filter of ID


When adding, scroll down to the "More" section. Checkmark allow multiple values.



Go to your Rest View


Add field of "View", select the view you added above. 


For contextual filter, use the replacement pattern for your author's field.
