DeepSeek Harness Office Plugin (dsh-office)

dsh-office is an open-source DSH Windows plugin designed to address file locking and formatting loss issues caused by default Office skills when generating files. It uses the COM interface to enable AI to perform real-time collaborative editing directly in open Word, Excel, and PowerPoint files. Core features include real-time modification of document content and layout (supporting styles, equations, citations, and three-line tables), Excel data cleaning and analysis (automatic overview, formulas, and charts), and theme-based PowerPoint generation with slide layout control. The tool has zero installation dependencies and does not require Python, while supporting batch operations and rendering verification, greatly improving office productivity in Windows environments.
