LockXLS

LockXLS is a software application which provides a security solution for Microsoft Excel spreadsheets, namely protecting it from unauthorized viewing and use, through a password, trial period and hardware-based activation code. It caters to advanced users.

The interface of the tool is professional-looking and intuitive, letting you start a new project by specifying an output directory for the locked files and setup package. You can include as many spreadsheets as you want into the project, using either the file browser or drag-and-drop method.

The protection method can be selected between protection without activation, password, trial period, hardware or USB-based activation code, or serial number.

Every method comes with its own set of configurable options. For instance, concerning the password mode, you can combine it with the trial period protection mode, write a message, input EULA, display a splash image, and more.

You can generate an activation code and verify the deactivation one, assign and edit the string table, install or open a sample project, and create an MSI package, among other options provided by LockXLS.

The program is pretty low-demanding when it comes to the system resources, using minimum CPU and RAM. No error dialogs have been shown in our tests, and the app did not hang or crash. Thanks to its wide array of settings, LockXLS should please the entire audience.
