# Microsoft Powerpoint

<figure><img src="/files/ZZt3KbeC2HkHwFwqtX9U" alt="" width="234"><figcaption></figcaption></figure>

Microsoft PowerPoint is a presentation program for creating and displaying slide shows. This module provides functionality to load and process PowerPoint files using officeparser.

This module provides a sophisticated PowerPoint document loader that can:

* Load PowerPoint presentations
* Extract text from slides
* Split content into individual slides
* Handle slide numbering
* Process metadata per slide
* Support multiple slide formats
* Handle various slide separators

## Inputs

### Required Parameters

* **PowerPoint File**: The PowerPoint file(s) to process (.ppt, .pptx)

### Optional Parameters

* **Text Splitter**: A text splitter to process the extracted content
* **Additional Metadata**: JSON object with additional metadata
* **Omit Metadata Keys**: Comma-separated list of metadata keys to omit

## Outputs

* **Document**: Array of document objects containing metadata and pageContent
* **Text**: Concatenated string from pageContent of documents

## Features

* Text extraction
* Slide separation
* Metadata handling
* Error handling
* Memory-efficient processing
* Heuristic slide detection
* Content filtering

## Slide Detection Methods

### Pattern Recognition

The loader attempts to identify slides using common patterns:

* "Slide X" markers
* "Page X" markers
* "X/Y" page numbers
* Underscore separators
* Dash separators
* Multiple newlines

### Fallback Mechanisms

If pattern recognition fails:

1. Split by double newlines
2. Treat content as single slide

## Document Structure

Each document contains:

* **pageContent**: Extracted text content from the slide
* **metadata**:
  * slideNumber: Sequential slide number
  * documentType: "powerpoint"
  * Additional custom metadata

## Content Processing

* Empty slides are filtered out
* Leading/trailing whitespace removed
* Minimum content length validation
* Reasonable slide count validation

## Metadata Attributes

Default attributes include:

* slideNumber: Slide number (number)
* documentType: Type of document (string)
* Custom metadata from input

## Notes

* Uses officeparser for extraction
* Handles various slide formats
* Intelligent slide detection
* Content validation
* Memory-efficient processing
* Error handling for invalid files
* Flexible output formats
* Robust fallback mechanisms
