In FreeMarker, you can use the ?eval directive to evaluate a string as a FreeMarker expression. Here’s how you can convert a string representing a JSON object into an actual object in an Advanced PDF/HTML template: <#assign jsonString = ‘{“line”:”1″,”remaining”:1}’> <#assign jsonObject = jsonString?eval?json_string> <tr> <td>Line: ${jsonObject.line}</td> <td>Remaining: ${jsonObject.remaining}</td> </tr>
