TATEKANBridge converts existing business files into TATEKAN-ready Markdown, reviewable knowledge, and later structured data.
- Initial PoC: SI sheet Excel to Markdown conversion on GCP
- Input scope can later expand from Excel to Word, PDF, PowerPoint, CSV, HTML, images, audio, and archives through MarkItDown
- Current issue: #667 TATEKANBridge PoC
0. Current Scope
- Convert
★SI表 社外用（2025年度計画策定時)into raw Markdown, sheet-level Markdown, and a merged Markdown document. - Build the first GCP-managed Markdown conversion environment for the PoC.
- Keep DB conversion, WebUI generation, and ServiceItem dictionary registration outside this first scope.
1. Pipeline
- MarkItDown: existing file to raw Markdown
- Prepare: analyze sheets, row counts, empty areas, and conversion units
- Transform: normalize each sheet into reviewable Markdown without treating AI output as the source of truth
- Merge: combine reviewed sheet Markdown into a final document for later ServiceItem and WebUI work
2. Safety
- Keep the original file as the source of truth.
- Treat Markdown as an intermediate artifact.
- Use human review before any later DB or app use.
- Do not use free Colab for real customer or business files.
