# VBridge Agent

> VBridge Agent is the first framework that puts Claude Code inside the Excel VBA development loop. Claude writes new VBA, imports it to the VBE, runs 45+ automated checks, reads its own test log, and fixes root causes autonomously — without copy-paste and without the live workbook ever being at risk.

VBridge Agent turns the Excel VBA Editor — historically a closed door to AI — into a place where Claude Code can develop, test, and self-correct VBA on its own. The bridge is built on native Windows scripting that ships with every Windows install, so no new runtimes, interpreters, admin rights, or IT exceptions are required. Everything runs locally; no code, workbook, or data ever leaves the developer's machine.

## What it is

- **Category:** AI coding assistant / developer tooling for Excel VBA
- **Built by:** Noam Brand (independent VBA developer & automation engineer)
- **Platform:** Windows 10 / 11, Microsoft Excel with VBA
- **Requires:** Claude Code CLI, Claude Pro or Max subscription
- **License / Price:** Free
- **Website:** https://vbridge.netlify.app/
- **Hebrew version:** https://vbridge.netlify.app/he

## Key capabilities

- Claude writes VBA and imports it directly into the VBE (no copy-paste)
- 45+ automated checks run after every change (syntax, compile, runtime, regression)
- Claude reads its own test log and identifies failures by itself
- Autonomous root-cause fixing with permanent guard checks added after each fix
- Isolated-copy safety: every session runs on a protected copy — the live workbook is never touched and can be restored with one click
- 100% local execution — code, workbooks, and data never leave the machine
- Documentation is generated automatically as a side-effect of the test loop

## Who it's for

- VBA developers, Excel power users, and financial / operations engineers maintaining large Excel-based systems
- Teams that cannot use cloud-based AI coding tools because of data sensitivity or IT restrictions
- Developers who have tried general AI assistants for VBA and found them only useful for tiny snippets, not full development cycles

## How it differs from alternatives

- **Claude / ChatGPT Excel add-ins** — operate on spreadsheet *cells* and have zero access to the VBA editor or to any macro the user runs. VBridge Agent runs the full write → import → test → fix loop inside the VBE.
- **General AI chat (copy-paste workflows)** — require the human to be the runtime: paste code, run it, read the error, paste it back. VBridge Agent removes the human from that loop.
- **Excel MCP servers** — focused on reading/writing cells, not on developing VBA code with feedback from runtime errors.
