Microsoft Access Modernization
Access databases contain critical business logic hidden inside binary .mdb and .accdb files.
Because these aren't plain text source files, we need to extract the code before the analyzer can run —
and we do that with you.
Important: Direct Analysis Not Available for Access Files
The downloadable EXE analyzer cannot open .mdb or .accdb files directly.
For Microsoft Access applications, please contact us first.
The process is straightforward — we'll walk you through it, step by step, at no cost.
What's Inside Your Access Application
Access applications are richer — and more fragile — than they appear. Here's everything we extract and document as part of the analysis.
-
VBA Modules Code-behind forms, standalone standard modules, and class modules — every line of business logic
-
Forms and Report Objects Total count, subform nesting depth, and complexity classification for every form and report
-
Queries — All Types Select queries, action queries (UPDATE / INSERT / DELETE), pass-through queries to back-end databases, and UNION queries
-
Tables and Relationships Full data model inventory — table count, field counts, relationships, and referential integrity rules
-
Linked Tables External data sources: Excel spreadsheets, SQL Server tables, SharePoint lists, and other Access databases
-
Macros Access macro objects — including embedded macros and data macros on tables
-
ActiveX Controls and External References Registered OCX controls, DLL dependencies, COM automation references — all migration blockers we identify and flag
-
Access Version Detection Access 97 through Microsoft 365 — version drives compatibility and urgency of migration
The Access Modernization Challenge
Access is deceptively powerful — and deceptively difficult to migrate. Understanding why helps set realistic expectations.
Binary Format
.mdb and .accdb files are proprietary binary containers — not plain text you can open in a code editor or check into version control.
Extracting the VBA source, query definitions, and schema requires either Microsoft Access itself or specialized extraction tooling.
This is why we can't just drop your file into the standard analyzer.
VBA Code Complexity
Access VBA is event-driven and tightly coupled to the UI — Form_Open, Button_Click, Field_AfterUpdate.
The visual form designer is not HTML. Business logic is embedded directly in the presentation layer.
Migrating to a web app or .NET application requires rethinking the architecture from first principles, not just translating code.
The Single-User Trap
Most Access applications were designed for 1–5 concurrent users. Many organizations tried to scale by enabling SharePoint integration or network file shares — but this introduces file locking, corruption risks, and performance collapse. The right path is a modern web application or a .NET backend with a proper database, not adding layers on top of a fundamentally single-user tool.
Our Process for Access Applications
We've designed a streamlined process specifically for Access. No risk to your data — we only ever need the source code, not the records.

You Contact Us — Free 30-Minute Consultation
Tell us about your application — what it does, how many users, which version of Access, what database backend if any. No commitment, no sales pitch. Just a conversation to understand your situation.

We Provide a Safe Extraction Script or Guide
We'll give you a simple VBA script you run inside Access that exports all code modules, query definitions, and schema to plain text files. Alternatively, we'll walk you through using Access's built-in export tools. This takes 5–15 minutes.

You Send Us the Exported Text Files
Send us the exported
.bas,.cls,.frm, and query text files. No database data is needed — we only analyze source code and structure, never your business records or personal data. -

We Run the Analyzer and Generate Your Reports
Our analysis engine processes the extracted source files and produces the full inventory report: code metrics, complexity scores, dependency maps, and business risk assessment.

We Review Results With You and Recommend a Path Forward
We walk through the findings together and recommend a modernization strategy — whether that's a full rewrite to .NET and React, a phased migration, or a structured replacement project.
Why Modernize Away from Access
Access is not a bad tool — it was revolutionary for its era. But it was never designed for what organizations now ask of it. Here's how it scores against modern requirements.
| Capability | Risk Level | Why It Matters |
|---|---|---|
| Multi-user Support | High Risk | Access uses file-level locking. At scale, this causes data corruption, split errors, and lost records. The Jet/ACE engine was never designed for concurrent writes. |
| Security | Critical | No built-in authentication, no SSL, no role-based access control. The database is a file on a network share — anyone with file access has database access. User-Level Security (Access 97–2003) was removed in later versions. |
| Cloud Deployment | Critical | Access requires Windows and the ACE/Jet engine. It cannot run on Linux, cannot deploy to Azure App Service, and cannot run in a container. Cloud migration is blocked entirely. |
| Developer Talent | High Risk | Access VBA is not taught in modern curricula. The developer pool is small and aging. Hiring for Access expertise requires premium rates and long searches — and is getting harder every year. |
| Maintainability | High Risk | Binary format makes version control impossible. You cannot diff two versions of an .accdb file in Git. Branching, code review, and CI/CD pipelines are fundamentally incompatible with the format. |
