Losing format after doing mail merge

Hi y’all,

I’m working with the Aspose and facing these problems:

  • Style applied on the merge fields all lost after merging

  • Then, i tried with another approach by removing the MERGEFIELD keyword inside field code, the applied style can work properly but not so really. Merge fields that had been removed these keywords piled up on top of the document:

This is my code to execute the mail merge process:

public static void generateMailMergePdfFromJson(Document template, String json, String outputFilePath) throws ParserConfigurationException, SAXException, IOException, Exception {
//Remove merge field with empty value and if the row are empty=> remove paragraph
| MailMergeCleanupOptions.REMOVE_UNUSED_REGIONS
| MailMergeCleanupOptions.REMOVE_CONTAINING_FIELDS);

    ObjectMapper objectMapper = new ObjectMapper();
    JsonNode jsonNode = objectMapper.readTree(json);
    ArrayNode arrayNode = objectMapper.createArrayNode();
    JsonNode rootNode = objectMapper.createObjectNode();
    ((ObjectNode) rootNode).set(Dictionary.ROOT_TAG_NAME, arrayNode);

    //To call custom merge data with html code
    template.getMailMerge().setFieldMergingCallback(new HandleMergeFieldInsertHtml());

    // Add main merge field based of main root tag name
    template.accept(new TableTagHandler(Dictionary.ROOT_TAG_NAME));
    // Merge fields
    template.getMailMerge().executeWithRegions(new JsonMailMergeDataSet(new JsonDocument(rootNode, Dictionary.ROOT_TAG_NAME)));
    template.save(outputFilePath, SaveFormat.PDF);

Anyone has a taste for this issue, please help me.
