# About Grunt

> Understand Grunt's rule-based model and why it separates content from design

Grunt is a PowerPoint add-in for professionals who spend a lot of time building and updating slides.

## Why Grunt exists

The legacy support introduction frames the core problem clearly:

* PowerPoint slides are often built from static shapes and text boxes.
* Static slides are tedious to maintain when data changes.
* Small content updates can force large manual layout changes.

Grunt takes a different approach by separating content from design.

## Separate data from design

In Grunt:

* Data carries the values and structure.
* Rules decide how that data should look.
* Visual Grids combine the two into slide-ready output.

This lets you update the data without rebuilding the slide from scratch.

## Let the data drive the slide

Legacy support guidance describes rules as a powerful form of conditional formatting.

That means you can:

* Apply formatting based on values
* Stack multiple behaviors on top of each other
* Reuse the same logic across many rows, columns, and objects

The result is faster updates and more consistent presentation output.
