Platform note
VBA
Visual Basic for Applications is Microsoft's embedded macro and scripting environment for Office desktop applications. It was widely used to automate repetitive work, control data movement, and encode business rules close to spreadsheets, forms, reports, and user actions.
In many organizations, VBA became the practical way to extend Excel, Access, Outlook, and Word without building a separate application stack.
What it was typically used for
Teams used VBA for calculations, approvals, report generation, data cleansing, imports and exports, customer correspondence, reconciliations, and specialist workflows that lived inside Office rather than in a separate line-of-business system.
Why it still matters in rescue work
VBA often survives because it sits inside tools people still open every day. The business may think it is using a spreadsheet or a database, while the real operating logic lives in macros, form events, and procedural code that only a few people understand.
Artifacts to inspect when extracting business logic
- Standard modules: shared procedures, helper functions, and central calculations.
- Class modules and form modules: event-driven behavior tied to screens, controls, and workbook or document actions.
- References and external libraries: hidden dependencies on COM objects, drivers, and other Office components.
- User forms and controls: data-entry rules, operator flow, and validation behavior.
- Workbook, document, or application events: startup routines, save logic, scheduled tasks, and automation triggers.
- Embedded SQL and file operations: database writes, imports, exports, and integration points.
