Excel Workbook Protection

Encrypted XLSM

    The Encrypted XLSM approach wraps your Excel workbook (XLSM or XLSB) into a Windows EXE or macOS APP file. On first launch, the application is activated for use on a specific computer and generates a Data Folder on disk.

    The master workbook launches directly into Excel or the App optionally presents the Open Data File window to manage named instances of the master workbook.

    Each workbook is stored in the Data Folder as an encrypted workbook file that can only be used by your activated application.

    Once running in Excel, all workbook and VBA features work the same except a user cannot save to an unprotected workbook.
