    How Excel Recovery Works

    1

    Upload Din Fil

    Upload your password-protected XLS or XLSX file through our TLS-encrypted portal. Our system automatically detects the encryption type — RC4 for legacy XLS or AES-128/256 for modern XLSX — and estimates recovery difficulty, password length, and expected time to crack. You receive an instant analysis before any commitment.

    2

    Server-drevet genopretning

    Our dedicated GPU cluster runs millions of password combinations per second using dictionary attacks, brute-force algorithms, mask attacks, and AI-driven pattern matching. You can optionally provide password hints — keywords, dates, character types — which narrows the search space and dramatically improves both speed and success rate.

    Once your password is found, you receive it via email with a detailed breakdown of the recovery time and method used. You pay only on successful recovery. Simple 4-digit PINs and passwords from the top 10,000 most common passwords are recovered completely free during the Fast Check phase — no payment needed at all.

    Common Excel Recovery Scenarios

    Excel is the backbone of business data across every industry. We help users regain access in situations like these:

    Financial reports, budgets, and P&L statements locked with a forgotten password
    Accounting ledgers and bookkeeping records from a former employee who left without handing over credentials
    Client databases and CRM exports protected years ago with a password nobody remembers
    Inventory and stock tracking spreadsheets created for a project that has since been archived
    Payroll records and HR spreadsheets containing salary data that must be accessed for tax filing
    Sales forecasts, revenue projections, and investor decks locked before a key meeting
    Old spreadsheets migrated from a previous job or a defunct company
    Tax calculation worksheets used for annual filing that were encrypted as a security precaution

    Workbook Password vs. Sheet Protection

    Excel has two entirely different protection mechanisms. Knowing which one you are dealing with saves time and effort:

    Workbook Г…bningsadgangskode

    This prevents opening the file entirely. You see a password prompt before any data is shown, and without the correct password the spreadsheet content remains completely inaccessible. This is the type of lock our service is designed to break. It uses either RC4 (XLS) or AES (XLSX) encryption on the entire file stream, meaning every cell, formula, chart, and macro is encrypted until the correct key is supplied.

    Sheet / Workbook Structure Protection

    This allows you to open and view the file but restricts editing — you can see the data but cannot modify cells, add sheets, or change formulas. Sheet-level protection can be bypassed in seconds using VBA macros, Python openpyxl scripts, or hex editing tools. Nej brute-force password recovery is required. If you can open your Excel file at all, you do not need a password recovery service.

    Why Excel Passwords Get Lost

    Microsoft Excel has supported file-level encryption since Office 97, giving users the ability to password-protect their spreadsheets. While this is a powerful security feature, it comes with a serious downside: if the password is lost, the data inside becomes completely inaccessible. Unlike cloud services such as Google Sheets or Microsoft 365 Online — which offer password reset flows — Excel's local encryption is absolute. There is no 'forgot password' button, no recovery email, and no backdoor. The only path back to your data is either remembering the password or performing a cryptographic attack against the encrypted file header. This is where professional recovery services come in. Using specialized hardware and optimized software, we can test billions of password candidates against your file's encryption until the correct one is found. With modern GPU acceleration and smart attack strategies, even complex passwords become recoverable within a practical timeframe.

    LostMyPassPro vs. Other Recovery Options

    Nejt all password recovery methods are created equal. Here is how LostMyPassPro compares against the most common alternatives available in 2026:

    LostMyPassPro (Online Service)

    GPU-accelereret cloud cluster with AI-driven attack strategies. Upload and forget — we handle everything server-side.

    SuccesrateHojest — best-in-class attack combinations
    Omkostninger$9.99 upfront + $34.99 on success. Fast Check covers short passwords for free.
    VerdictBest for non-technical users and complex passwords that need prolonged GPU attacks.

    PassFab / iSunshare (Desktopsoftware)

    Commercial Windows software that runs on your own computer. Requires installation and uses your local GPU.

    SuccesrateGood — limited to your hardware capability
    Omkostninger$30-$80 one-time license, but no pay-on-success model
    VerdictAcceptabel for simple passwords on powerful local machines. Nej good if your computer has no dedicated GPU.

    hashcat / John the Ripper (DIY Gratis)

    Open source password cracking tools used by security professionals. Requires technical expertise, hash extraction, and command-line knowledge.

    SuccesrateAs good as your hardware and skill level
    OmkostningerGratis (software) but requires a powerful GPU ($$) and hours of manual setup
    VerdictIdeal for technically skilled users who already own high-end Brugervenlighed and understand hash extraction workflows.

    VBA / Macro Bypass (DIY Gratis)

    Simple VBA script or hex editor to remove sheet-level protection. Only works if you can already open the file.

    Succesrate100% for sheet protection — zero for open passwords
    OmkostningerGratis, 30 seconds of work
    VerdictPerfect if you can open the file. Useless if you are seeing a password prompt on open.

    Gratislance Recovery (Fiverr / Forums)

    Independent technicians offering recovery services, often reselling hashcat or commercial tools.

    SuccesrateVariable — depends on the freelancer's setup
    Omkostninger$15-$100 per attempt, with no guarantee
    VerdictCheap but risky. Nej accountability, no privacy guarantees, and variable technical capability.

    Best Practices for Excel Password Security & Recovery

    • Always maintain offline backups of critical spreadsheets — a password-protected file that also has a backup copy somewhere safe gives you a fallback option.
    • Use password hints that are meaningful to you but not obvious to others. Dates, pet names, and inside references work well as anchors for memory.
    • Store your passwords in a reputable password manager (Bitwarden, 1Password, or KeePass) so you never need recovery in the first place.
    • For shared spreadsheets, use a team password manager rather than giving everyone the same Excel password — if someone leaves, rotate the password easily.
    • If your file is from Excel 97-2003 (.xls), take advantage of the weaker RC4 encryption: recovery is significantly faster and cheaper than modern AES-protected .xlsx files.
    • When creating a new encrypted spreadsheet, write down the password on paper and store it in a secure location — it sounds old-fashioned but it works every time.

    Transparent Priser — Pay Only on Success

    Our pricing model is designed to be fair and transparent. There are two paths: the Fast Check is completely free and covers short and common passwords — if your password is a 4-digit PIN or appears in the top 10,000 most common passwords, we find it at no charge. If the Fast Check is unsuccessful, we escalate to Dybdgenopretning + AI at $9.99 upfront plus $34.99 on successful recovery. The upfront fee covers dedicated server time and priority queuing; the success fee is charged only when we deliver your password. There are no hidden fees, no subscriptions, and no recurring charges.
