Strong Excel workbook protection & licensing, made simple

All-in-one Excel protection
Three jobs, one desktop tool. Pick a step to see what is inside.
Hide what is inside your workbook
Encrypt the workbook, hide formulas cell by cell, and compile your sensitive VBA subs to cryptic bytecode.
Excel Compiler
Wrap XLS, XLSX, XLSM, or XLSB into a stand-alone Windows EXE. The source spreadsheet never ships to your users.

- 32-bit, 64-bit, or universal
Formula + VBA protection
Hide formulas per cell while keeping them functional. Compile VBA subs to bytecode so the original source disappears from the workbook.
- Per-cell formula manager
- VBA to bytecode compiler
From spreadsheet to paying customer
Four steps, one desktop tool. No scripting, no SaaS server on our side. You keep the workbook, the keys, and the customer relationship.
