You deliver a custom solution to a client. Without compilation, the client can take your code, terminate your maintenance contract, and modify it themselves. With DoneEx, you remain the only one who can update the logic—giving you recurring business leverage.
Excel is the standard for business modeling, but it suffers from a major security flaw: the VBA project. If you email an Excel file containing a proprietary pricing model or a complex simulation, anyone with basic technical knowledge can extract the logic. DoneEx VbaCompiler for Excel
: To get the best results, it is recommended to use strict data type declarations and avoid "Variant" types where possible to ensure the fastest native code execution. VBA Compiler Comparison with Standard Protection Excel Built-in Protection DoneEx VbaCompiler Password-protected VBA Project Binary compilation to C++ DLL Visibility Code can be viewed if password is cracked Source code is physically removed from the file Standard VBA execution Often faster due to native code optimization Difficulty to Bypass Relatively easy with common tools Extremely difficult/Impossible to decompile Best Practices for Compilation To maximize the benefits of the DoneEx VbaCompiler , developers should: Declare Data Types : Explicitly define variables (e.g., Dim i As Integer instead of just ) to help the compiler optimize the machine code. Use High Optimization You deliver a custom solution to a client
VBA itself is a 32-bit technology. DoneEx compiles to 32-bit DLLs. On 64-bit Excel, you must run in compatibility mode or use the 32-bit version of Office. This is a Microsoft limitation, not a DoneEx flaw. Excel is the standard for business modeling, but
Users can bind compiled files to specific hardware IDs or registration keys, preventing unauthorized distribution.
: It supports both 32-bit and 64-bit versions of Microsoft Excel. No Coding Changes
