The result to aim for
Vincent Lacomme, an accountant and auditor, has been generating Excel files (formules, formatting, graphics) in Claude since September 2025, and is transforming a written meeting report into a PowerPoint slideshow to his charter.
What was done
Interview published on April 21, 2026 on Altanum. He turned to Claude on the advice of a fellow trainer (Julien Catanese Aubier), for professional prose. Rupture cited: file generation Excel enriched, "this was not possible at this point before." Daily use: voice transcription of meetings then presentation Claude / PowerPoint, "without manual editing" once the charter skill is in place. "Claude produces complete Word documents in three minutes. I then spend half an hour reading and refining. It also creates local tools (file cleaning, data logging) via Claude Code, offline for use. It recalls US hosting and anonymization.
