Runtime Error 1004: Application/Object-defined error

Invalid range reference, protected sheet, or file access issue.

How AI Debugging Works

More than just finding errors – the AI explains and fixes them

Rapid Error Analysis

Spot typical causes: out-of-range, type mismatches, uninitialized objects, invalid ranges, timing/event pitfalls.

Robust Error Handling

Standardized handlers with error codes, context metadata, cleanup logic, and optional fallback flows.

Clear Explanations

Understand immediately what your code does. The AI explains complex logic clearly and shows why the error occurs.

Corrected Code Included

Not just find errors, but fix them automatically. The AI provides working code you can use directly.

Logging & Tracing

Debug.Print/Immediate, file logs, central logger, verbosity switches — reproducible scenarios made easy.

Integrated in VBA Editor

The add-in integrates seamlessly into Excel. Analyze and fix errors without switching programs.

Frequently Asked Questions

Is this really free?

Yes, you get 10 free queries. That's enough for most debugging sessions. For higher usage, affordable subscriptions start at $9.99/month.

Is my code stored?

No. Your data is only used to process your request and then deleted. No storage, no training with your content. GDPR-compliant processing via Microsoft Azure.

Does it work with all Excel versions?

The add-in works with Excel 2016, 2019, 2021 and Microsoft 365 on Windows 10 and Windows 11. Both 32-bit and 64-bit versions are supported.

How does the AI help with debugging?

It evaluates error messages and code paths, proposes precise fixes, and generates logging/handler templates — with concise root-cause notes.

Does it handle event/timing issues?

Yes. It recognizes common race conditions (Change/Calculate/Activate) and suggests decoupling or queueing patterns.

Is this suitable for large projects?

Absolutely. Unified handlers, module scopes, and test scaffolds scale across many modules.

Can the AI also create new code?

Yes! Besides debugging, the VBA Code Generator can create complete macros from natural language. All functions in one add-in – download free now.
