VBA code tool

The VBA Code Tool analyzes Visual Basic for Applications code snippets to identify patterns that affect reliability and maintainability. It targets macros used in Excel and Access, enabling developers, data engineers, and IT staff to validate logic before deployment. The tool is designed for hands-on code reviewers who want repeatable checks, consistent style, and actionable feedback without running the workbook. By consuming plain text code, it can operate in IDE-agnostic contexts and support quick refactoring decisions.

Core capabilities include syntax-aware linting, detection of long procedures, nested loops, ambiguous variable names, and insufficient error handling. Optional advanced checks assess complexity, potential side effects of external calls, and naming consistency with project conventions. The tool can emit a corrected_code snippet alongside a concise lint report, helping teams track changes and justify modifications in audits or change-management processes.

Workflow integration emphasizes deterministic outputs: a patch-ready code block, a rationale for each suggestion, and a measurable estimate of improvement. Typical use cases include cleaning legacy macros, standardizing error handling, preparing code for teammates, and reducing debugging time in critical spreadsheets. Outputs are designed to be reviewed and applied directly in the VBA editor or through version-control workflows.

Inputs include the code_snippet, target Office version, analysis_mode (lint, refactor, optimize), and optional constraints. The tool validates inputs, produces a lint_report with issue descriptions, and returns a corrected_code block. It does not execute code; it relies on static analysis and best-practice patterns. This makes it suitable for governance and QA workflows in finance, operations, and analytics teams.
