01 Protect & Secure

Lock down your workbook and its logic

Start here

Protect your workbook

Turn an Excel workbook into a protected Windows EXE in a few clicks. Strong encryption, formulas hidden, structure locked.

  • Strong encryption of the workbook payload
  • Single Windows EXE output
  • Structure and sheets locked
  • Anti-debug runtime
See the protection workflow

Security for Excel workbooks

Anti-debugging, anti-tamper, and runtime integrity checks make sure your compiled workbook resists analysis and modification.

Review the security stack

Protect Excel formulas

Encrypt your most valuable formulas. Users can run them but cannot read or copy the underlying logic.

Hide your formula logic

VBA code protection

Strip plaintext VBA from your file. Combined with the VBA Compiler, code is encrypted at rest and JIT-decoded at runtime only.

Encrypt VBA at rest

Save options

Decide whether end users can save changes. Lock the file as read-only, allow encrypted saves, or restrict saving entirely.

Configure save behavior

02 License & Activate

Decide who can run your workbook, and on which machine

Start here

Online activation

Issue per-user activation keys, revoke them at will, track activations, and run trials with deadlines or usage limits.

Hardware-locked keys

Dongle protection

Tie your workbook to a USB hardware dongle for maximum security. The workbook will not run without the dongle plugged in.
