Brand-Docs: Open-Source Tool for Claude to Generate DOCX, PPTX, XLSX from Templates

Brand-Docs is an open-source tool that enables Claude to generate Office documents (DOCX, PPTX, XLSX) while strictly adhering to your company's existing brand templates — preserving layout, styles, and images without recreating them.

As posted on r/ClaudeAI, the author was tasked with making Claude repeatedly generate Office documents based on company templates with variable content. Testing Claude's official document-generation skills showed good but not reliably consistent results for preserving template design.

Key details from the source

• The solution extracts characteristics from templates and reuses them faithfully when generating new documents.
• After three days of work (accelerated by AI), the tool was built and open-sourced.
• The author emphasizes that AI is good at generating documents, but needs a robust process to extract and replicate template characteristics.
