Talk to Excel in DeepSeek Harness: read, edit, clean and report on spreadsheets by conversation. Re-checks every formula after each edit, repairs silent errors, and needs no local Excel for the core work (charts and PDF export use Windows Excel).

Flagship multimodal vision hub for DeepSeek Harness: ~40 tools, PDF drag-and-drop, LaTeX formulas, complex tables, QR codes, UI flow diagrams, and multi-model consensus.
