LockXLS 4.4

LockXLS adds copy protection features to your Excel workbook. It makes formulas and VBA code unavailable to customer, adds various registration options – generates hardware based Computer Code, creates Activation Code to unlock workbook on customer’s PC, customize the messages shown to customer during registration. Locked workbook may have a trial period and splash screen. Also it will be converted to an application, which does not have any external dependencies and could be easily distributed.

You should not write a code which creates hardware dependent Computer Codes, registration interface and other features needed for distribution. All of them are provided to LockXLS, you should only select needed options in the project and enter your own messages.

LockXLS encrypts all formulas and VBA Code in the Excel document. This document can be opened only by LockXLS Runtime and only if registration checking was successfully passed.

LockXLS Runtime Module blocks access to formulas and VBA code in the locked file. User cannot get access to formulas in locked file, because all possible ways are blocked by LockXLS. All data is encrypted and decrypted on-the-fly only when it is needed. LockXLS does not create temporary files from which user can extract information.

All Excel’s features are supported in locked file. You need not redesign your file or change macros. Our primary goal is to make locked file work in same way as usual Excel documents.


  • Your spreadsheet is protected with a:
    • Hardware based Activation Code (the workbook is locked to specific PC)
