For people who write their own LAMBDAs

IntelliSense for the
named LAMBDAs you write

Lambrary gives the named LAMBDA functions you write the same IntelliSense Excel reserves for its built-ins — argument hints, descriptions, and allowed-value dropdowns as you type, plus a way to browse, document, and export your library. Currently in private alpha.

Why I built this

Excel gives its built-in functions rich IntelliSense — argument hints, descriptions, the signature as you type. Write your own named LAMBDA and you get none of it: no hint of what arguments it takes, no reminder of what each one means, no good way to document or share it. Lambrary closes that gap.

Today it's an authoring tool — IntelliSense, documentation, and export for the LAMBDAs in a workbook. The longer plan is to grow it into a way to manage, share, and distribute LAMBDA libraries across a team. It's a Windows add-in built on Excel-DNA, and I'm building it first for my friends in the competitive Excel community.
