    Two Types of Excel Protection — Which Do You Have?

    An open password encrypts the whole workbook. Sheet or workbook protection is a separate, lighter restriction.

    Processus de récupération

    Comment ça marche

    1. 1

      Upload the File

      Upload your encrypted .xlsx or .xls file. Our system detects the exact encryption type automatically.

    2. 2

      Password Recovery

      Our GPU cluster runs billions of password attempts — dictionary attacks, rule mutations, and brute-force patterns. Runs 24/7.

    3. 3

      Open Your File

      When we find the password, you receive it by email. Enter it in Excel and your file opens. Pay only on success.

    Open Password (Encryption)

    The file is fully encrypted — Excel asks for a password before showing anything. This is the hard one: the entire file content is AES-encrypted. You cannot open it, view it, or read its sheets without the correct password. This is what our service recovers.

      Sheet/Workbook Protection

      The file opens fine, but some sheets or the workbook structure are locked. You can view content but cannot edit certain cells or unhide sheets. This type of protection can often be bypassed without the original password using VBA macros (for older Excel) or third-party tools.

        Common situations

        Excel Format & Encryption Reference

        The file extension and encryption generation set realistic expectations before a recovery starts.

        • .xls — RC4 40-bit (Office 97-2003): High — legacy encryption, fast attack
        • .xlsx — AES-128 (Excel 2007-2010): Good — depends on password complexity
        • .xlsx — AES-256 (Excel 2013+): Moderate — complexity-dependent
        • .xlsm — AES-256 (macro-enabled): Moderate — same as modern .xlsx
        • .xltx / .xltm — Same as matching .xlsx/.xlsm: Same recovery rate as base format
