Why I built this

Named LAMBDA functions changed what serious work in Excel can look like. The tooling around them hasn't caught up. No in-cell IntelliSense, no parameter hints, no easy way to document or share a LAMBDA library across workbooks or across a team.

Lambrary closes that gap. It's a Windows desktop add-in built on Excel-DNA, designed for the analysts, quants, and modeling teams who write LAMBDAs they actually have to maintain.
