Hi Sandhya,As of AEM Forms 6.2 release, you could pre-populate an
adaptive form using XML data. If you have JSON data as per business
requirements, you could convert the JSON data to XML data for
pre-populating the form. If you wish to know more details on how
pre-populating adaptive form fields work, you could refer to details at
[1]In 6.3 release, we are also planning to incorporate the notion of
pre-populating adaptive form using JSON Data.Thanks,Rishi[1]
