# The Report Engine

The Boomi Console Report Engine takes a well defined JSON input (like a [list of components](/boomi-console/library/the-report-engine/the-render-dataset/components-dataset.md)) and renders this using a FreeMarker 2 template into any kind of output file.

{% hint style="info" %}
[Apache FreeMarker](https://freemarker.apache.org/docs/index.html) is a populate and proven template engine written in JAVA.

> *"Apache FreeMarker™ is a template engine: a Java library to generate text output (HTML web pages, e-mails, configuration files, source code, etc.) based on templates and changing data. Templates are written in the FreeMarker Template Language (FTL), which is a simple, specialized language (not a full-blown programming language like PHP). ..."*

The template engine is based on Freemarker 2.3.32. Please refer to[ Apache FreeMarker Manual](https://freemarker.apache.org/docs/index.html) for more information about the templating engine.

Output files will be written to [`/OutDir`](/boomi-console/commands/arguments/common-arguments.md#outdir-o) into a file named: `<TemplateName>_<TimeStamp>.<templateExtension>`. This ensures unique filenames to not lose any information

{% hint style="info" %}
The latest file is always written to the same file (without time-stamp). This was implemented to have a non changing reference to the latest file.
