With Codex/Claude Excel plugins, spreadsheets become auditable programming languages
joecole · x · 2026-10-22
In a reposted take, alexdong argues that Excel was already the most popular programming language for scientists and analysts before AI. With Codex/Claude plugins for Excel, prompts now extend the existing language of formulas and references while staying fully compatible with the underlying data storage. In his view, this turns Excel into both an auditable system of record and an inspectable, debuggable programming language — something he says you have to experience to appreciate.
