Documnent Marge with HTML inside the Json

Hello, i would like to use the Document Merge feature of the Document Services API to create a pdf by using a  MS Word template and a JSON file.

Is it possibile to have HTML inside the JSON file ?

For example if i have in the Json

"paymentTerms": "<strong>Hello world</strong>"

when I generate a PDF from a word template that have written

Payment terms

{{paymentTerms}}

I would like to see Hello world in the generated document.

Is that possible with document merge ?

If not how do you suggest to obtain the same result ?

My Json is generated from a POJO object.

Thank you for the answers!
