Learn how to remove the password from a protected Excel worksheet, as well as how to crack the password for an encrypted Excel file. In most cases, removing a password from an editing-locked worksheet inside an Excel file is fast and easy! But if you need a password to even open the file, things get a bit tricky. There's no legitimate way to decrypt an Excel workbook without using a password cracker, which can be a very resource-intensive process, depending on the complexity of the password. Still, it's worth a try!

Quick Tips to Opening a Password Protected Spreadsheet

If you have an Excel sheet that you can open but can't edit, you can get around this by converting the sheet into an XML file and deleting the code that makes the sheet password protected. While this sounds hard, it's actually very easy to do. If the sheet is fully encrypted, you must use a password cracker.

Removing Password Protection from a Sheet

  1. If only a sheet in the Excel workbook is protected—that is, if you can open the Excel file and view its contents but not edit it—then you can use this method to remove the password protection on both Windows and Mac computers.
    • If the Excel file itself is encrypted and requires a password even to view the contents, this method will definitely not work. You can try using a password cracker , but there are no guarantees.
    • There's a chance this method won't work if the file was protected using the Microsoft 365 version of Excel. [1]
  2. The easiest way to do this is by double-clicking the Excel file. If the file opens and you can click Read Only to view the file, or if the file opens like usual when you double-click it, the file is not encrypted. [2]
    • If you're immediately prompted for a password upon double-clicking the file and not given the option to open it read-only, the file is encrypted, and you cannot use this method to open it.

  3. In Finder or the Windows File Explorer, click the Excel file that contains the sheet you want to unprotect, then press Ctrl + C (Windows) or Command + C (Mac) and paste it into another folder by pressing Ctrl + V (Windows) or Command + V (Mac). [3]
    • This is necessary in case you accidentally corrupt the original version of the file in the process.
  4. Skip this step on a Mac. If you're using a Windows computer, you'll need to make sure you can view and change file extension names by doing the following:
    • Open File Explorer by pressing Windows key + E .
    • Click View .
    • Check the "File name extensions" box.
  5. To do so:
    • Windows — Right-click the Excel file, click Rename , delete the "xlsx" text at the end of the file's name, and type in zip . Make sure that you keep the period between the file's name and "zip". Press Enter and click Yes when prompted.
    • Mac — Select the Excel file, click File , select Get Info , delete the "xlsx" text at the end of the file's name, and type in zip . Make sure that you keep the period between the file's name and "zip". Press Return and click Use .zip when prompted.
  6. This process will vary depending on your computer's operating system:
    • Windows — Right-click the ZIP folder, click Extract All... in the drop-down menu, and click Extract when prompted. The extracted folder should open.
    • Mac — Double-click the ZIP folder, then wait for the extracted folder to open.
  7. This opens the folder. [4]
    • If the extracted folder didn't open for some reason, first double-click the regular folder with the same name as your ZIP folder.
  8. It's near the top of the "xl" folder.
  9. Depending on your computer's operating system, do one of the following:
    • Windows — Right-click the sheet you want to unlock (e.g., "Sheet1"), select Open with in the drop-down menu, and click Notepad in the resulting pop-out menu.
    • Mac — Click the sheet you want to unlock (e.g., "Sheet1"), click File , select Open With , and click TextEdit .
  10. Find the "sheetProtection" section that's inside the "< >" brackets, then delete everything from "<sheetProtection" to the closed bracket ("/>") on the other side of the sheet protection algorithm.
  11. Press either Ctrl + S (Windows) or Command + S (Mac), then click the X (or red circle on a Mac) in the corner of the text editor.
    • If multiple sheets in the workbook are protected, you'll need to remove protection from each separately. Open any other protected sheet in your text editor and remove the same line, saving each as you go.
  12. Click the "Back" button to go back to the "xl" folder, then select the "worksheets" folder and press either Ctrl + C (Windows) or Command + C (Mac) to copy it.
  13. This is the file you renamed and then extracted earlier (the one ending in .zip if you're using Windows). If you're using a Mac, double-click the new folder with the same name as the ZIP file.
  14. Navigate to the "worksheets" folder by double-clicking the "xl" folder, and then delete the "worksheets" folder inside. Next, right-click a blank place in the window and select Paste to paste the copied version.
    • If you're using Windows, you've now added the copied folder back into the existing ZIP file.
    • If you're using a Mac, you've added the copied folder to the extracted folder.
  15. If you're using a Mac, press Control as you click the folder that you previously extracted—it's the folder with the same name as your spreadsheet. Then, select Compress from the menu. The folder is now a ZIP file again. [5]
  16. Close the ZIP file, then do one of the following:
    • Windows — Right-click the ZIP folder, click Rename , replace the "zip" text with "xlsx", and press Enter . Click Yes when prompted.
    • Mac — Click the ZIP folder, click File , click Get Info , replace the "zip" text in the title with "xlsx", and press Return . Click Use .xlsx when prompted.
  17. Now that you've removed password protection from the sheet, you'll be able to edit it as needed.
    • If you receive an error that the Excel sheet is damaged, you probably removed extra code when attempting to remove the password protection algorithm. Repeat the above steps, making sure to only remove the text between the brackets (</>) and the brackets themselves.

Cracking a Workbook Password

PDF download Download Article
  1. Modern versions of Excel, such as Excel 2019 and Microsoft 365, use advanced encryption techniques that make the methods used by password crackers virtually useless due to how long the password can take to crack. You'll have an easier time cracking a shorter password without special characters, although it may still be possible to crack more complex passwords using the right app.
    • It is impossible to crack an Excel file without purchasing a password cracker, as free versions of reputable password crackers usually only cover up to Excel 2010.
    • If your Excel file truly is encrypted, double-clicking the Excel file will prompt you for a password before you can view the file's contents. If this is the case (and you don't know the password), you'll need a password cracker to view its contents.
  2. You can get it from https://www.passfab.com/products/excel-password-recovery.html . While many applications may claim to remove password encryption from password-protected Excel workbooks, PassFab is known for being safe and easy to use. [6] It can also decrypt Excel files made in all versions of Excel, including 2019 and Microsoft 365. There are two drawbacks, though:
    • One is that the app only works on Windows, so Mac users will need access to a PC. [7] There may be a Mac alternative, but none have proven to be as reliable. If you don't have access to Windows, try searching for another Excel password-cracking app. Just be sure to research the app thoroughly before downloading and installing, as there are many rogue apps out there.
    • The other is that the software is not totally free—some basic features in the trial version may help crack your password, but you'll need to pay for a license if the password is complex. If you just need to crack one workbook, you can go for the one-month option that's only $15.95. [8] Just remember to cancel the subscription before the month ends so you aren't billed in the future.
  3. After installing the app, you'll find it in your Windows Start menu.
  4. It's the first of two options. You should choose this option if you are required to enter a password upon opening the workbook.
    • If you just need to remove the password from a protected sheet inside a workbook and couldn't do so by editing the XML file , you can select Remove Excel Restriction Password instead and follow the on-screen instructions.
  5. This tells PassFab which file to crack. [9]
  6. Keep in mind that no matter which option you choose, cracking a password takes time. The app has to try all different combinations of letters, numbers, and symbols. This can take anywhere from a few minutes to a few months! There are three options you can choose from:
    • Dictionary Attack is a good option if you think the password is a simple word from the dictionary. You can also provide your own list of words to add in addition to the dictionary, such as common passwords used by your organization. Just add those potential passwords to a text file, save it, click Settings next to "Dictionary Attack," and select that file.
      • This is the only free option, and it only includes a limited dictionary. [10] If you want to gain access to more options, click Upgrade Now to purchase a license.
    • Brute Force with Mask Attack is a great option if you know any parts of the password, or want to include certain letters, numbers, or symbols in your cracking attempt. If you choose this option, click Settings beside it to customize the length of passwords to try, which characters to use, and prefixes and/or suffixes. Depending on the length and complexity of the password, this option can take a long time—hours, days, even weeks!
    • Brute Force Attack is just like the previous option, except it's best for when you really have no idea what the password could be. It tries all possible combinations until it can figure out the password, which can take a long time, depending on its length.
  7. Let the password cracking begin! PassFab will attempt all possible combinations that are consistent with the cracking option you selected. The app will continue trying combinations until it guesses the password or runs out of options to try. [11]
    • This can take a while, and can consume a lot of resource on your computer. If you need to pause the cracking, click the stop button (the square) until you're ready to resume, and then click the play button to start again.
    • When PassFab finds the password, it displays it in plain text. You can then copy or type the password into Excel when opening the file to view its contents.
    • Depending on the contents of the Excel file, you might need to abandon your efforts if you haven't found the password within a reasonable period of time.

Troubleshooting

  1. First, make sure you don't have Caps Lock pressed while typing in your password. If you don't have Caps Lock enabled and you're certain you are typing the password correctly, you can use one of the above methods to remove the password protection from your file.
  2. If you have Malwarebytes, you may be encountering a bug in the interaction between these two programs.
    • Open Malwarebytes and go to Settings > Security > Exploit Protection > Advanced Settings > Application Behavior Protection .
    • Scroll until you find "Excel macro 4.0 abuse prevention."
    • Uncheck any boxes next to this option.
    • Click Apply to save your settings.

    What do I do if I get an error extracting a ZIP file?

    The ZIP file itself may have a password rather than the spreadsheet; you can't use this method to crack the password. Try the methods in Remove the Password from a Zip File Without Knowing the Password .

  • Question
    What do I do if I can't open my password protected Excel file?
    Community Answer
    Password crackers are the fastest and easiest option if you need to remove an Excel password. There are free password recovery tools, such as FreeWordExcel and Straxx. Unfortunately they have limited functionality, so if they won’t help in you that case, then you can try commercial software such as Excel password recovery master, Excel password recovery online services like Password-Find, there are a lot of options.

      • Only use these methods if you are the file's owner or an authorized user. Cracking a password for a file that isn't yours is not only unethical but may also be illegal, depending on the file's contents and your location.

      About This Article

      Article Summary X

      To open a password protected Excel file, start by double-clicking the file to see if you can read it. If it opens, copy and paste the file to create a backup in case you make a mistake. Then, open File Explorer, click “View” and check the “File name extensions” box. Once you’ve done that, right click the Excel file and rename the file extension to “.zip.” Next, right-click the file and select “Extract files.” After you’ve extracted the files, open the “xl” folder and then “worksheets.” Open the sheet inside with Notepad, search for the “sheetProtection” section inside the diamond brackets, then delete the text until the closed bracket. When you’ve deleted the sheet protection, save the file. Then, copy the “Worksheets” folder from the “xl” folder. Open the zip file you renamed earlier, and replace the “worksheets” folder inside with the one you just copied. To finish off, change the zip folder back to an Excel file by changing the extension back to “.xlsx.” For more tips, including how to crack an encrypted Excel file, read on!
