Spreadsheet Unlocker – Knowledge Base
Welcome to the Spreadsheet Unlocker Knowledge Base
Welcome to the Spreadsheet Unlocker Knowledge Base – your all‑inclusive guide to effortlessly removing passwords from a wide range of Microsoft Excel files. Whether you’re dealing with a locked workbook that’s stopping you from accessing vital data, or you’ve simply forgotten the password to a spreadsheet you need to edit, this resource will walk you through every step of the process, ensuring you can quickly regain full control over your documents without compromising data integrity.
Our tool supports all major protection‑enabled spreadsheet formats
Our tool supports all major protection‑enabled spreadsheet formats, giving you the flexibility to work with any file you encounter in the professional or personal arena. Input formats accepted by Spreadsheet Unlocker include: .xlsx, .xlsb, .xlsm, .xltm, .xlam, and the legacy Excel 97‑2003 (commonly known as .xls). This extensive compatibility means you can upload virtually any modern or older Excel file that has password protection applied, whether it’s a standard workbook, a macro‑enabled file, a template, or an add‑in. The moment you upload one of these files, our engine begins analysing the encryption layers, deciphering the password hash, and applying advanced recovery techniques to unlock the content.
Once the password has been successfully removed
Once the password has been successfully removed, you have the freedom to save the unlocked spreadsheet in any of the same supported formats, allowing you to maintain consistency with your existing workflow or convert to a more suitable type for future use. The output formats you can choose from are identical to the input options: .xlsx, .xlsb, .xlsm, .xltm, .xlam, or Excel 97‑2003. This ensures that after unlocking you can directly replace the original file, share it with collaborators who may require a specific format, or archive it in a legacy format for compliance purposes. The conversion process is seamless, preserving all formulas, charts and embedded objects while stripping away the password protection.
