Modernize Access and Excel/VBA applications with control

When Access databases, Excel workbooks or VBA macros have evolved into business-critical applications, a big-bang rewrite is rarely the best first step. I assess business logic, data structures and dependencies and create a practical modernization path.

TECHNOLOGIES & RISKS

Understand mature solutions before changing them.

Microsoft Access

Forms, reports, queries, VBA code, linked tables and multi-user operation are assessed as one system.

Excel & VBA

Macros, formulas, add-ins, file dependencies and embedded process logic are made transparent.

Data & interfaces

Access/ACE, SQL Server, ODBC, CSV, Office automation and external systems are mapped as dependencies.

APPROACH

From technical baseline to controlled modernization

1. Secure

Preserve files, source code, data and dependencies in a reproducible baseline.

2. Assess

Identify operational risks, bottlenecks, manual process steps and hard-to-maintain Access or VBA components.

3. Modernize

Stabilize, separate the database, replace selected modules or migrate towards .NET and SQL in manageable steps.

NEXT STEP

Assess your Access or Excel/VBA solution before replacing it.

The Legacy Software Check identifies what can remain, where the risks are and which modernization steps make economic sense.
