One XLS Padlock User License. Description: XLS Padlock is an advanced solution for protecting your Excel workbooks. Acting as a compiler, it transforms your Excel workbooks into secure applications. This allows you to safely distribute your files, control user access to your Excel workbooks, and prevent copying of your sheets. XLS Padlock offers multiple protection options, including dongle protection, USB locking, and hardware-locked activation keys that work only on a specific computer. You can also choose to protect certain formulas, allowing end users to use them without being able to copy them into another Excel file. Additionally, XLS Padlock can convert parts of your VBA code into encrypted bytecode, making it impossible for anyone to copy your VBA code. Secured applications can expire after a certain number of days or runs, or on a specific date. Online activation and validation enable remote licensing possibilities. The secured applications are standalone and only require Microsoft Excel to function. All Excel features are supported. Compatible with Excel 2024 down to Excel 2002, in both 32-bit and 64-bit versions, and with Microsoft 365.
