xlsx

XLSX CLI for AI agents. JSON to stdout by default (raw text for --format csv|markdown). Polars+fastexcel for data reads (7-10x faster than openpyxl), openpyxl for metadata/writes, three rendering engines for visual capture (Aspose → Excel → LibreOffice), oletools for VBA.

Handle the request directly. Do NOT spawn sub-agents. Always write the output file the user requests.

This skill enables creation, editing, and analysis of Excel spreadsheets programmatically. Claude should apply these patterns when users need to generate data reports, financial models, automate Excel workflows, or process spreadsheet data.
