What is PPTX Analysis?
This Openclaw Skills utility leverages the power of MinerU by OpenDataLab to transform PowerPoint presentations into developer-friendly Markdown. It provides a robust way for AI agents to understand presentation structures, text blocks, and content hierarchy without needing a full Office suite.
Whether you need a quick glance at slide content using the flash-extract method or a deep dive into tables and formulas with a full token-based analysis, this skill streamlines the process of presentation auditing and content review for various Openclaw Skills workflows.
PPTX Analysis Use Cases
- Automated auditing of corporate presentation decks for quality and compliance.
- Converting slide content into structured Markdown for RAG (Retrieval-Augmented Generation) workflows.
- Quick programmatic inspection of .pptx files to verify content layout and hierarchy.
- Extracting complex tables and formulas from educational materials for technical documentation.
How PPTX Analysis Works
- The user provides a local .pptx file path or a remote URL to the skill interface.
- The skill invokes the mineru-open-api CLI to process the document content.
- For quick tasks, the flash-extract mode processes the file without requiring an API token.
- For detailed analysis, the tool uses an authenticated token to extract complex elements like formulas and tables.
- The structured Markdown output is either streamed to stdout for immediate processing or saved to a designated output directory.
PPTX Analysis Setup
To get started with this part of the Openclaw Skills ecosystem, install the CLI tool via npm or Go:
npm install -g mineru-open-api
# Alternatively, via Go (macOS/Linux)
go install github.com/opendatalab/MinerU-Ecosystem/cli/mineru-open-api@latest
To use full extraction features, set your environment variable after obtaining a token from mineru.net:
mineru-open-api auth
export MINERU_TOKEN="your-token"
PPTX Analysis Data Schema & Taxonomy
The skill organizes extracted presentation data into the following schema:
| Element | Description |
|---|---|
| Slide Content | Extracted text preserved in hierarchical Markdown format (H1 for titles, etc). |
| Layout | Structural layout preservation including text block sequencing. |
| Technical Metadata | Page counts, file size limits (10MB for flash), and language hints. |
| Advanced Objects | Tables and formulas captured specifically in full extraction mode. |
PPTX Analysis Advanced Features
- Support for both local file paths and direct URLs for flexible presentation analysis.
- Language hints via the --language flag to optimize extraction accuracy for specific locales.
- Direct integration with the MinerU open-source document intelligence engine for reliable parsing.
- High-speed flash-extract mode for rapid, token-free processing of smaller decks under 20 pages.
