Microsoft Powerpoint

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
