Docxtemplater - Javascript - hightlight undefined values

Question

I'm using docxtemplater to create a word document based on JSON values (using surveyJS). In case some questions are not answered, the variable shows "undefined" in the final document.

How can I make sure that any "undefined" output is highlighted? I found some answers on how to use nullGetter to replace "undefined" with a custom string but nothing on text background.

The JSON looks something like this:

{
    "nameIndividual": "John Smith",
    "mgmt": "Management Name",
    "mgmtName": "Tim Test",
    "address": "854 Test Avenue, Example City",
    "email": "test@management.com",
    "socialMediaOptions": [
        "Twitter",
        "YouTube",
        "Instagram",
        "Facebook"
    ]
}

Is there a way to do this in the word template itself without having to write {#nameIndividual == undefined}Undefined{/} for every single variable...

If not, how can this be done with Javascript?

Any help is highly appreciated!

Thanks!

You would have to use the docxtemplater HTML module for this. It supports setting a background-color style to html elements. Look here:

Instead of undefined you could add <span style="background-color: red">Undefined<span> for the missing value.
