What is PPT Extract?
The PPT Extract skill is a high-performance document intelligence integration designed for Openclaw Skills. It leverages the MinerU engine from OpenDataLab to parse complex presentation files, transforming them into structured Markdown data that AI agents can easily analyze and process. Whether you are dealing with legacy binary .ppt formats or modern XML-based .pptx files, this skill ensures that the textual and structural information within your slides is preserved and accessible.
By integrating this capability into your workflow, you enable your AI agents to 'read' presentations as if they were standard text documents. This is particularly valuable for automated documentation, content repurposing, and building searchable knowledge bases from corporate slide decks. The skill supports both local file processing and direct extraction from URLs, making it a versatile addition to any Openclaw Skills library.
PPT Extract Use Cases
- Converting corporate presentation decks into searchable Markdown documentation for internal wikis.
- Enabling AI agents to summarize slide content during automated research tasks.
- Batch processing legacy .ppt archives into modern, developer-friendly text formats.
- Extracting text and data from presentations hosted on remote URLs without manual downloads.
How PPT Extract Works
- The skill receives a command to process a PowerPoint file from a local path or a remote URL.
- It authenticates with the MinerU API using a secure token stored in the environment variables.
- The file is processed by the MinerU engine, which performs layout analysis and text extraction.
- The extracted content is structured into Markdown, maintaining the logical flow of the slides.
- The resulting data is either streamed to stdout or saved to a specified output directory for the AI agent to consume.
PPT Extract Setup
To use this Openclaw Skills integration, you must install the MinerU CLI and configure your API token:
# Install via npm
npm install -g mineru-open-api
# Or install via Go (macOS/Linux)
go install github.com/opendatalab/MinerU-Ecosystem/cli/mineru-open-api@latest
# Set up your authentication
export MINERU_TOKEN="your-token-here"
# Or use the interactive setup
mineru-open-api auth
