VBA Code Converter

About This Tool

This tool provides automated translation of VBA code into VB.NET or other supported targets to assist developers migrating legacy macros. It analyzes common VBA constructs (Sub/Function, loops, conditionals, error handling, and object model references) and applies rule-based mappings to produce equivalent target-language code. It is designed for teams modernizing Excel or Access macros, consultants, and developers maintaining historic VBA portfolios.
Conceptually, the tool operates as a layered transformer: lexical parsing to an intermediate representation, normalization of API usages, and target-language code generation with configurable mappings. Users supply the VBA snippet, select the target language, and optionally enable advanced mappings for ranges, collections, and common Excel objects. The system validates syntax and flags constructs with known limitations.
What makes it valuable: speed, reproducibility, and a documented mapping log that supports audits and reviews. It handles simple to moderately complex macros, including user-defined functions, without requiring a full IDE. It provides an export-ready code bundle and a human-readable mapping report to guide manual refinements.
Common use cases include migrating Excel macros to VB.NET for a Windows service, converting database-side VBA (Access) to VB.NET or C#, and providing a starting point for code modernization projects. The tool differentiates itself with domain-specific VBA patterns, error-aware translation, and an option to preserve comments and line breaks in the target code.
