Hello Jonathan,
I hope you are well.
- Please try to compose a string and then add to the "Fill out a document" module. In this example I used the "Compose a string" module to create a bundle with my desired output:

My document looks like this:

My module mapping looks like this:

My output includes line breaks:

A Condition tag enables you to wrap certain parts of a text that should be rendered conditionally. To wrap the conditional text, place it between the opening and closing tags. The name of the opening tag is prepended with a hash sign #, the name of the closing tag is prepended with a slash /

Template:
> {{#hasPhone}}Phone: {{phone}} {{/hasPhone}}
> {{#hasEmail}}Email: {{email}} {{/hasEmail}}
Created document:
> Phone: 123456
Loop or section
A Loop or section tag enables you to repeat parts of a text. Similarly to the Condition tag, to wrap the repeated text, place it between the opening and closing tags. The name of the opening tag is prepended with a hash sign #, the name of the closing tag is prepended with a slash /.
When using loops, you can choose to employ either the Fill out a document module or the Fill a document with a batch of data aggregator module.
Fill out a document
If you employ Fill out a document module, the content of the field Value has to be an array of collections, where:
- Each collection corresponds to one data entry and contains one item entry
- Item entry contains a collection with two items key and value
- Item key contains the tag's name
- item value contains the tag's value
