Excel AI Bridge
An add-in and a local bridge so an AI assistant can read and write the workbook you have open, while cells you mark stay off the wire.
This is an invite-only alpha. It runs on Windows with a Google account only (Excel for Windows desktop, and Google sign-in for claude.ai). There is no Mac, Excel for the web, or Microsoft-account path yet. If you already have an invite, start with Install. If you do not, request access.

Alpha is invite-only. Tell us who you are and what you want to do. If we can include you, we email the invite. Do not send workbook contents.
