About This Tool

Assuming a VBA project across Office apps, the tool analyzes code for syntax errors, references, and common runtime pitfalls. It supports single modules or full projects and returns a structured report.
The analysis is rule-based and relies on lexical parsing and lightweight data-flow heuristics to identify issues such as missing Option Explicit, undeclared variables, and deprecated constructs. It highlights the location of each issue and provides suggested fixes to improve reliability.
The results include a summary score, per-item details, severity levels, and suggested refactorings. It is useful for pre-deployment reviews, legacy macro audits, and cross-project consistency checks. The tool does not execute code; it reasons about static code to surface potential problems.
Overall, it helps developers, analysts, and IT admins accelerate VBA quality assurance and enforce coding standards across Excel, Access, and Outlook automations.

Frequently Asked Questions

Find Quick Answers

What formats are supported for input?

Input supports pasted VBA code or file uploads for multi-module projects. It accepts .bas, .cls, or raw code snippets and analyzes across modules without executing the code, providing a safe, read-only assessment.

Does it enforce coding standards?

Yes. It checks for Option Explicit usage, explicit variable declarations, consistent naming conventions, and avoidance of common anti-patterns like On Error Resume Next and implicit error handling, providing actionable remediation steps and references to relevant VBA best practices.

Can I export or reuse results?

Results can be exported as JSON or CSV for integration into CI pipelines or documentation. Reports include per-issue details, severity, suggested fixes, traceable references to affected modules, and export-friendly metadata for auditability.

How is severity determined?

Severity is based on impact and likelihood derived from rule checks (syntax errors and undefined references are high, style issues are moderate). False positives are minimized by contextual checks across modules.
