About
This skill empowers Claude to manage complex spreadsheet workflows, from high-level data analysis using pandas to building production-grade financial models with openpyxl. It enforces rigorous standards such as zero-error formula verification, industry-standard color coding (blue for inputs, black for formulas), and detailed documentation for hardcoded values. By integrating with LibreOffice via a recalculation script, the skill ensures that all spreadsheets remain dynamic, updated, and verified for structural integrity, making it an essential tool for developers and analysts who need to automate Excel tasks without sacrificing professional quality.
