Live workbook demonstration

before you buy.

The Excel formula bar on a yellow averaging cell showing =PLEvalForm(5) instead of the real formula, with a note that the original formula is no longer accessible.
Click a protected yellow cell: the formula bar shows an opaque PLEvalForm call, while the cell still computes the correct result.

Two flavors of the same workbook.

The first build runs as soon as you launch it. The second build requires an activation key, so you can experience the complete licensing flow from order to first run.

All builds are code-signed so Windows can verify they have not been altered.

Demo without required activation.

Run it immediately. Test compiled VBA, formula protection, and the splash screen. This build is fully unlocked and opens directly in Excel.

Published by G.D.G. Software SAS, code-signed (Authenticode).

The compiled Markbook workbook running inside Excel, titled Markbook Demo, with a yellow DEMO: A PUPIL MARKBOOK banner and two sheet tabs, VBA Protection Demo and Formula Protection Demo.
After the splash screen, the compiled EXE opens the workbook in Excel with two demo sheets: one for VBA, one for formulas.

What the compiled workbook lets you try.

Compiled VBA macros

Open the VBA editor in the demo: the source for the sort routine is gone. Only a CallXLSPadlockVBA stub remains, the rest runs from native bytecode.

Encrypted formulas

The yellow cells on the second sheet still compute correctly. The formula bar shows opaque calls instead of your model.

Custom splash screen

The EXE shows a branded splash before Excel opens. The branding is yours, configured at compile time from the XLS Padlock manager.

Code-signed binary

Windows verifies the publisher and integrity of the EXE before running it. Use your own certificate on your own builds.

The VBA editor opened on the compiled Markbook workbook, showing only CallXLSPadlockVBA stub calls where the SurnameSort and MarkSort routines used to be, with a note that the original VBA code is no longer accessible but functionality remains.
Open the VBA editor: the sort routines are gone. Only CallXLSPadlockVBA stubs remain, the logic runs from compiled bytecode.
