# Generate PDFs from a template in JavaScript

Here is your guide explaining how to generate document accurately and efficiently with JavaScript using Apryse SDK

## Overview

Apryse's office template generation framework enables the dynamic generation of PDFs:

* You provide a [template](/web/generate/template-based-generation/data-model.md) in the form of an Office document (such as .docx)
* You provide [replacement data](/web/generate/template-based-generation/data-model.md#allowed-formats-for-values) in JSON form
* Apryse SDK will efficiently generate a PDF by merging the data with the template
* Fully featured, with support for loops, conditionals, images, table generation, etc.
* Use your preferred office editor to design attractive templates, and Apryse will take care of the rest
* All logic is entirely contained within the SDK, with no external dependencies

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.apryse.com/web/generate/template-based-generation/generate-via-template.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `build a script that syncs our docs to a CMS` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
