Comprehensive Excel tool for opening, filtering, summarizing, charting, PDF exporting, and AI-based table analysis across multiple sheets.

This skill overpromises features it doesn't implement and omits the 'xlsx' dependency. Before installing: (1) don't assume it can create charts, export PDFs, or run AI analysis—ask the author or request source that implements those features; (2) expect it to read any local file path you give it, so don't open sensitive files with it unless you trust the code; (3) the missing dependency will likely cause runtime errors—ask for an updated package.json or a trustworthy package source (e.g., GitHub) and review the full source; (4) consider running it in a sandboxed environment first. If you need charting or PDF export, request proof of those implementations rather than trusting the README/SKILL.md alone.
