xlsx

Overview

XLSX is a skill from the Claude Office Skills repository that provides professional Office document creation and editing workflows for the command line. It packages the same document manipulation capabilities used by Claude Desktop for use with Claude Code, enabling Excel spreadsheet creation with formulas, formatting, and zero-error validation directly from the terminal.

Key Features

• Formula-Based Models - Build working Excel spreadsheets with formulas and a zero-error requirement, ensuring all calculations are valid and functional
• Professional Formatting - Apply color-coded inputs/formulas, custom number formats, years as text, and zeros formatted as dashes for polished financial models
• Multi-Format Support - Part of a suite covering PowerPoint (PPTX with HTML-to-PPTX conversion), Word (DOCX with tracked changes), Excel (XLSX), and PDF (form filling, merging, extraction)
• CLI Pipeline Integration - All scripts can run directly from the terminal, ready to integrate with CI/CD pipelines and automated workflows
• Automated Workflow - Claude Code reads the SKILL.md workflow, executes it step-by-step, and saves all outputs to organized output directories

Who is this for?

This skill is designed for developers and analysts who need to create professional Excel spreadsheets programmatically through Claude Code, particularly financial models with formulas and formatting. It is ideal for teams that want to automate document creation workflows from the command line or integrate Excel generation into CI/CD pipelines.
