Doubao Agent hands-on: DuPont analysis in Excel and in-place PPT edits
AI寒武纪 · wechat · 2026-11-05
A hands-on test of ByteDance's Doubao Agent desktop app covering a full office workflow:
- Data fetching: one prompt had the agent write Python to pull three financial statements, clean them, and save standard local Excel files plus reusable scripts.
- In-place formula writing: for a DuPont analysis (ROE decomposed into net margin, asset turnover, leverage), the agent created a new sheet inside the original Excel with live cross-sheet formulas, preserving existing data and formatting.
- PPT generation and in-place edits: it generated a research-report-style deck, then restructured a specific slide's layout and inserted comparison charts via natural-language commands, saving back to the same file.
- Cloud desktop: batch peer-company analysis ran on a cloud machine, viewable later from the phone app.
The author's takeaway: most AI office tools stall at "format shuffling," while deep local-file manipulation finally lets agents fit real workflows. Post includes a 30-day free-trial promotion.
