Referencing values dynamically between wiki pages

[EBro]

We have one master wiki page documenting a set of json values. We are building various clients which will be using these values, and we would like to refer to these values from several other wiki pages (each page describing how the value will be used for the client in question). 

Instead of manually maintaining several wiki doc pages, how can we dynamically refer to a json value at another wiki page?

The "include page" macro is not sufficient for our needs, as this includes a whole page. I have found the Excerpt and Excerpt Include Macros, but the drawback is that one can only include one excerpt per page. I have several variables I would like to include in one single page, - also from different source pages. 

I found the Multi Excerpt, and this can possibly meet my needs. However, this is not a free plugin:

I found that the topic is also discussed here:

Dear Elin, you could try "include page" macros.

It means that you can have a page with set of JSON values and show it into many confluence pages.
