Xlsx To Markdown

This skill is coherent for converting office files to Markdown, but take these precautions before installing or using it: (1) Understand that conversion uploads files to MinerU's cloud with no account or API key — do not upload sensitive or confidential documents unless you trust MinerU and have read their privacy policy. (2) Installing mineru-open-api via npm or go will run third-party code on your machine — inspect the package/repo (https://mineru.net and the linked GitHub repo) and review recent commits, owners, and issues. (3) Prefer running the CLI in a sandbox/container or on an isolated machine if you are unsure. (4) Verify package integrity where possible (checksums, repository tags). (5) If you need entirely local processing, consider local tools (pandoc, LibreOffice headless, python libraries like python-docx/mammoth) instead. (6) If you want higher privacy guarantees, ask the skill publisher about retention and deletion policies or use the CLI mode that requires auth for more controlled processing. If you provide additional artifacts (the mineru-open-api package link, GitHub repo contents, or the CLI binary), I can re-evaluate and raise the confidence level.
