Ppt Ocr

Convert and extract content from .ppt using MinerU (mineru-open-api).

Install

npm install -g mineru-open-api
# or via Go (macOS/Linux):
go install github.com/opendatalab/MinerU-Ecosystem/cli/mineru-open-api@latest

Quick Start

# OCR extraction (requires token)
mineru-open-api extract slides.ppt --ocr -o ./out/

# From URL
mineru-open-api extract https://example.com/slides.ppt --ocr -o ./out/

Authentication

Token required for extract and crawl:

mineru-open-api auth            # Interactive token setup
export MINERU_TOKEN="your-token" # Or via environment variable

Create token at: https://mineru.net/apiManage/token

Capabilities

• Supports local files and URLs
• Requires token (mineru-open-api auth or MINERU_TOKEN env)
• Supported input: .ppt
• Language hint with --language (default: ch, use en for English)
• Page range with --pages (where applicable)

Notes

• .ppt requires extract with token. Add --ocr for image-heavy slides.
• Output goes to stdout by default; use -o to save to file
