Mail merge mustache in Java

Powerful Java library to use mail merge operation with mustache template and user data.

This Java SDK allows you to use Mustache templates based on the Mustache syntax and execute mail merge operations on this logic-less template to fill the document with data from various data sources. You can export the result into the required document format: DOCX, PDF, HTML and other popular formats using Java.

Mail merge with logic-less templates using Java

Mustache is an alternative syntax for mail merge templates that consists of tags. To create a mustache template, use tags specified by the double braces as follows:

{{FirstName}}

In this case, you can find such tags inside the template and replace them with values determined by the key inside the tag. It is called logic-less templates because there are no if statements, else clauses, or for loops.

Mustache syntax is the only option that can be used with HTML or TXT templates that do not contain any fields. This means that with some template formats, such as Word templates, you can use both fields and mustache syntax, and with others, such as HTML or TXT, only mustache template syntax.
