JSON format using DBLINK

I have created a DB link using below query to link 12.1 version DB to 12.2 version DB. Since JSON is not supported in 12.1 version of the Oracle DB.

<span class="kwd" style="font-style: inherit; font-weight: inherit; font-family: inherit; color: var(--blue-800);">CREATE</span><span class="pln" style="font-style: inherit; font-weight: inherit; font-family: inherit; color: var(--black-750);"> </span><span class="kwd" style="font-style: inherit; font-weight: inherit; font-family: inherit; color: var(--blue-800);">DATABASE</span><span class="pln" style="font-style: inherit; font-weight: inherit; font-family: inherit; color: var(--black-750);"> LINK dblink_SBX<br/>   </span><span class="kwd" style="font-style: inherit; font-weight: inherit; font-family: inherit; color: var(--blue-800);">CONNECT</span><span class="pln" style="font-style: inherit; font-weight: inherit; font-family: inherit; color: var(--black-750);"> </span><span class="kwd" style="font-style: inherit; font-weight: inherit; font-family: inherit; color: var(--blue-800);">TO</span><span class="pln" style="font-style: inherit; font-weight: inherit; font-family: inherit; color: var(--black-750);"> SOURCEDB IDENTIFIED </span><span class="kwd" style="font-style: inherit; font-weight: inherit; font-family: inherit; color: var(--blue-800);">BY</span><span class="pln" style="font-style: inherit; font-weight: inherit; font-family: inherit; color: var(--black-750);"> SOURCEDB<br/>
