Can I generate a document in Confluence using Data ?

[Jira Admin]

I like to create a doc template and then pass data to it (JSON) and produce documents.

Right now, I can call the API and do it, but before I spend the time doing it, are there other options or marketplace apps? 

Looks like I need to learn the Atlassian Document Format (ADF), which I would like to avoid if I can.
