What problem does it solve? Editing Office documents programmatically usually requires heavy libraries or an installed Office suite. This Skill lets you create, read, proofread, and modify .docx, .xlsx, and .pptx files through a single dependency-free CLI, with structured JSON output and a layered read/edit/raw-XML strategy. ## Core Features & Use Cases - Document creation and editing: Build slides, paragraphs, tables, charts, pivot tables, and images with add/set commands using XPath-style paths and stable ID addressing. - Inspection and proofreading: Use view modes (outline, stats, issues, text, html) plus query with CSS-like selectors to find formatting or content problems, then verify with validate. - Live preview and review workflows: watch serves an auto-refreshing HTML preview with browser click-to-select, and mark proposes edits for human review before applying them. - Use Case: Generate a Q4 sales deck by creating a .pptx, adding slides with titles and styled text shapes, then running view issues and validate to confirm the file is clean before sharing. ## Quick Start Ask the assistant to create a PowerPoint file named report.pptx with a title slide and a text shape using officecli, then view its outline to confirm the structure.
