VBAssistant.ai

VBA Assistant is an Excel add-in that accepts natural language descriptions and returns VBA macros, UserForms, error fixes, and code explanations directly inside the spreadsheet environment. The core workflow skips the external chat window entirely: you describe the task in the add-in panel, receive generated code, and insert it into the VBA editor in one step. The same interface handles explanation of existing code and suggested fixes for compile or runtime errors.

The differentiating claim the vendor makes is privacy-oriented processing via Azure infrastructure, with an explicit statement that submitted code is not used to train the underlying model. For teams operating under internal data policies that prohibit sending proprietary business logic to consumer AI services, that backend architecture is the deciding factor — not the feature set.

The free tier is capped at ten requests, which the vendor states openly. That ceiling positions the tool as a trial-grade entry point, not a free production option. Teams writing macros at any meaningful frequency will exhaust the free allocation inside a single session. There is no self-hosted binary, no API surface, and no offline mode, so any team requiring air-gapped operation or wanting to integrate VBA generation into a broader automation pipeline has no path forward with this tool.

The add-in also stores reusable code snippets, which reduces re-prompting for recurring macro patterns — a practical detail for power users who maintain a personal macro library but want AI-assisted generation for net-new tasks.
