What This Skill Does
MinerU PDF Extractor converts PDF documents to structured Markdown via the MinerU API. It handles formula recognition, table extraction, and OCR. Two methods are available: uploading a local file in 4 steps, or submitting a public URL in 2 steps.
Handles complex PDF content like LaTeX formulas and embedded tables that basic text extractors miss.
When to use it
- Converting arXiv research papers to Markdown for note-taking
- Extracting tables from financial reports into structured text
- Batch processing academic PDFs to build a searchable knowledge base
- Parsing scanned documents with OCR into plain text
- Converting technical manuals with embedded formulas to Markdown
Example Workflow
Here's how your AI assistant might use this skill in practice.
User asks: Extract this arXiv PDF to Markdown: https://arxiv.org/pdf/2410.17247.pdf
- 1Run online_file_step1_submit_task.sh with the PDF URL to submit a parsing task
- 2Capture the returned TASK_ID from the script output
- 3Run online_file_step2_poll_result.sh with the TASK_ID and a target output directory
- 4Wait for polling to finish and the result ZIP to be downloaded and extracted automatically
extracted/full.md with the complete Markdown document, images in extracted/images/, and structured data in content_list.json
