Download XLS Padlock
XLS Padlock transforms Excel workbooks into protected Windows applications without requiring Excel on the target computer. The tool encrypts all sheet content, hides formula logic, and blocks VBA editor access. Compiled files run as standalone executables with optional license key requirements and hardware binding. The protection extends beyond simple password schemes by removing source code entirely from the distributed file.
The program includes a native VBA compiler that converts macros into binary machine code. This eliminates the possibility of source code extraction or modification. Formula cells remain functional while their underlying expressions stay hidden from users. Save operations can be restricted or disabled based on developer preferences. License management supports trial periods, activation limits, and remote revocation through an online portal.
Distribution options cover code signing, installer creation, and integration with WooCommerce or FastSpring payment systems. Each compiled workbook can include a splash screen, copyright information, and embedded auxiliary documents. The output executable resists debugging, memory inspection, and tampering attempts through runtime integrity verification.
