GridCraft: pure-Rust Excel rewrite with 500+ functions, driven via PowerShell
dfinke · x · 2026-10-18
Developer dfinke shows how to drive GridCraft — a clean-room Excel reimplementation in pure Rust with 500+ functions and native XLSX support — from PowerShell. Using --cmd flags to set cells A1=10, A2=20 and A3=SUM(A1:A2), he generates a real .xlsx that correctly evaluates to 30, with no Excel installation required. A practical option for programmatically producing spreadsheets in Office-free environments.
