Anton traced the bug to a subtle difference in floating-point handling between Excel’s internal binary and the standard C runtime. Excel had a custom rounding behavior in one of its spreadsheet functions; the VBA implementation relied on that quirk. Doneex’s implementation used IEEE-754 semantics by default. He wrote a localized fix: emulate Excel’s rounding for functions known to rely on it, and add a compatibility flag per workbook.
⚡ Compiled code runs faster than interpreted VBA. By converting your macros into a DLL, you bypass the overhead of the VBA interpreter, resulting in snappier, more responsive applications. doneex vbacompiler for excel top

The Silent Sentinel of Spreadsheet Security: DoneEx VBA Compiler for Excel
At its core, the DoneEx VBCompiler is a powerful add-in for Microsoft Excel (32-bit and 64-bit) that converts standard VBA code into native Windows executables ( .exe files). But that description sells it short. Unlike a simple "packager," this tool performs a true compilation. It takes your VBA modules, user forms, and embedded logic and translates them into machine-level code.
