VBA Compiler: Protect and Monetize Your VBA Code
A VBA compiler transforms your macros into compiled DLLs that cannot be decompiled. Stop sharing your source code — distribute professional, licensed applications instead.
What Is a VBA Compiler?
A VBA compiler is a tool that converts your VBA source code into compiled bytecode stored inside native Windows DLL files. The original VBA no longer exists — it is replaced by a binary representation that cannot be read, copied, or decompiled back to the original source.
This is fundamentally different from VBA project passwords (which can be removed in seconds) or code obfuscation (which still leaves your logic visible). A VBA compiler produces a completely different format — there is no VBA source left to steal.
VBA Padlock is a VBA compiler for Microsoft Office that handles the entire pipeline: parsing, bytecode generation, DLL packaging, code signing, and VBA Bridge generation. You write standard VBA code in a dedicated IDE, click Compile, and receive signed DLLs ready for distribution.

Why You Need a VBA Compiler
If you distribute VBA code — to clients, customers, or colleagues — a compiler is the only way to protect it for real.
Protect Your Intellectual Property
Your VBA source code contains proprietary formulas, business logic, and algorithms. A VBA compiler eliminates the source entirely — end users get the functionality without ever seeing how it works.
Sell Your VBA Applications
You cannot sell VBA code that anyone can copy and redistribute. A VBA compiler locks your code inside signed DLLs with built-in license keys, hardware locking, and trial periods — so you can charge for your work.
Distribute Professionally
Compiled DLLs are Authenticode-signed, trusted by SmartScreen and antivirus software. Your clients receive a professional package instead of an unprotected macro file.
Prevent Unauthorized Sharing
Without a compiler, anyone with the file has the code. With hardware-locked licensing, each copy is bound to a specific machine. Even if the file is shared, it won't activate without a valid key.
VBA Compiler vs. Other Protection Methods
Not all protection is created equal. Here is how a VBA compiler compares to passwords and obfuscation.
Protection level
None
VBA Password
Bypassed in seconds with free tools.
- • Source code fully accessible after bypass
- • Not encryption — just a flag in the file
- • No licensing or distribution features
Protection level
Low
VBA Obfuscation
Algorithm logic remains visible and reversible.
- • Code still present in VBA Editor (garbled names)
- • Automated deobfuscation tools exist
- • No licensing or distribution features
Protection level
High
VBA Compiler (VBA Padlock)
Source code eliminated. Bytecode cannot be decompiled.
- • Source code physically removed from Office file
- • Compiled bytecode inside signed DLLs
- • Built-in licensing, activation, and distribution
How VBA Padlock Works as a VBA Compiler
From source code to signed, distributable DLLs in four steps.
Write VBA Code
Use VBA Padlock Studio — a dedicated IDE with syntax highlighting and module management.
Compile to DLL
Click Compile. Your VBA is parsed and transformed into bytecode inside native DLL files.
Add Licensing
Configure license keys, hardware locking, trial periods, and online activation — all optional.
Distribute
Publish signed DLLs and ship your protected Office file. End users need only Microsoft Office.
Successful compilation — 32-bit and 64-bit DLLs generated and signed
More Than Just a VBA Compiler
All Office Applications
Compile VBA from Excel, Word, Access, and PowerPoint — workbooks, add-ins, documents, templates, and databases.
32-bit and 64-bit DLLs
Every compilation produces both architectures. The VBA Bridge loads the right one automatically.
Authenticode-Signed DLLs
Runtime DLLs are signed by G.D.G. Software. Trusted by SmartScreen, antivirus, and corporate policies.
Integrated Licensing System
License keys, hardware locking, trial periods, subscriptions, online activation, EULA — all built into the DLL.
Online Activation Server
Free PHP activation kit included. Deploy on your own server for fully automated license management.
Professional IDE
VBA Padlock Studio: ribbon interface, script editor, project explorer, key generator, test runner, and one-click distribution.
Built-in licensing system — activation keys, hardware locking, trial periods, and more
