Why You Need to Open Password Protected Excel Files
There are various reasons why you might need to open a password-protected Excel file. It could be because you’ve forgotten the password, the file was shared with you, or you simply want to retrieve some important data from it. Regardless of the reason, being able to access the contents of a password-protected Excel file can be crucial, especially in professional settings where maintaining data integrity is essential. By learning how to open password-protected Excel files without software, you can overcome this obstacle and regain access to your valuable data.
Method 1: Using the Excel Password Recovery Tool
Before we explore other methods, it’s worth mentioning that using a reliable Excel password recovery tool can be the most effective and efficient way to open password-protected Excel files. These tools are specifically designed to crack Excel passwords and help users regain access to their files. While this method requires the use of software, it is often the quickest and most reliable solution, especially if you’re dealing with complex or strong passwords.
Here are the steps to open a password-protected Excel file using an Excel password recovery tool:
1. Download and install a reputable Excel password recovery tool on your computer.
2. Launch the software and import the password-protected Excel file into the program.
3. Choose the appropriate password recovery method based on the complexity of the password (e.g., Brute Force Attack, Mask Attack, etc.).
4. Configure the settings according to your requirements and start the password recovery process.
5. Once the password is recovered, the software will display it, allowing you to access the Excel file.
Pros:
– Quick and effective method for opening password-protected Excel files.
– Can crack complex and strong passwords.
– Easy to use with user-friendly interfaces.
Cons:
– Requires the use of specialized software.
– Free software may have limitations or restrictions on password length and complexity.
Method 2: Removing Password Protection via ZIP Extraction
Another method to open password-protected Excel files without software involves using the ZIP extraction technique. This technique takes advantage of the fact that Excel files are essentially ZIP archives that contain various XML and other files.
Here are the steps to remove password protection via ZIP extraction:
1. Change the file extension of the password-protected Excel file from .xls or .xlsx to .zip (e.g., rename "file.xlsx" to "file.zip").
2. Extract the contents of the ZIP file by right-clicking on it and selecting the "Extract All" option.
3. Open the extracted folder, locate the "xl" folder, and navigate to the "worksheets" or "charts" folder within it.
4. Look for an XML file with the name "sheet" followed by a number (e.g., "sheet1.xml", "sheet2.xml", etc.).
5. Open the XML file using a text editor (e.g., Notepad) and search for the keyword "sheetProtection".
6. Delete the entire line that contains the "sheetProtection" keyword and save the changes.
7. Compress the extracted folder back into a ZIP file.
8. Change the file extension of the ZIP file back to its original .xlsx or .xls extension.
9. Open the modified Excel file using Microsoft Excel. You should no longer require a password to access its contents.
Pros:
– Does not require specialized software.
– Solves password protection by manipulating file structure.
– Compatible with most versions of Microsoft Excel.
Cons:
– Tinkering with the ZIP file structure can lead to file corruption if not done correctly.
– May not work with all password-protected Excel files.
– The process can be time-consuming for multiple files.
Method 3: VBA Macro to Bypass Password Protection
Visual Basic for Applications (VBA) is a programming language integrated with Microsoft Excel that can be used to automate tasks and manipulate Excel files. One of its features includes the ability to bypass password protection on Excel files.
Here are the steps to bypass password protection using a VBA macro:
1. Open the password-protected Excel file in Microsoft Excel.

Method 4: Protect Unprotected Sheets Method
If you’re unable to open a password-protected Excel file using the previous methods, you can try the Protect Unprotected Sheets method. This method involves protecting the existing unprotected sheets in the Excel file and then deleting the password-protected sheets, effectively opening the file without the need for a password.
Here’s how to open a password-protected Excel file using the Protect Unprotected Sheets method:
1. Open the password-protected Excel file in Microsoft Excel.
2. Press "Alt + F11" to open the VBA Editor.
3. In the VBA Editor, click on "Insert" and select "Module" to create a new module.
4. Within the module, paste the following code:
"`vb
Sub PasswordRemover()
Dim i As Integer, j As Integer, k As Integer
Dim l As Integer, m As Integer, n As Integer
Dim i1 As Integer, i2 As Integer, i3 As Integer
Dim i4 As Integer, i5 As Integer, i6 As Integer
On Error Resume Next
For i = 65 To 66: For j = 65 To 66: For k = 65 To 66
For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66
For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66

If ActiveSheet.ProtectContents = False Then
For Each ws In ThisWorkbook.Worksheets
On Error Resume Next
ws.Protect Contents:=False
ws.EnableSelection = xlNoRestrictions
If Err.Number = 0 Then
ws.Delete
Exit For
End If
On Error GoTo 0
Next ws
Exit Sub
End If
Next: Next: Next: Next: Next: Next
