Vba To Password Protect A Worksheet

[Yazmín Bohon]

Movethe pointer to cells for which the Locked box is unchecked on the Protection tab of the Format Cells dialog box. By default, users can select unlocked cells, and they can press the TAB key to move between the unlocked cells on a protected worksheet.

Change any of the options in the Format Cells or Conditional Formatting dialog boxes. If you applied conditional formatting before you protected the worksheet, the formatting continues to change when a user enters a value that satisfies a different condition.

Make changes to graphic objects including maps, embedded charts, shapes, text boxes, and controls that you did not unlock before you protected the worksheet. For example, if a worksheet has a button that runs a macro, you can select the button to run the macro, but you cannot delete the button.

View scenarios that you have hidden, making changes to scenarios that you have prevented changes to, and deleting these scenarios. Users can change the values in the changing cells, if the cells are not protected, and add new scenarios.

Use strong passwords that combine uppercase and lowercase letters, numbers, and symbols. Weak passwords don't mix these elements. Passwords should be 8 or more characters in length. A passphrase that uses 14 or more characters is better.

Optionally, to control the ability to edit protections for the entire sheet with a password, select Sheet protection password, enter and confirm the password, and then select Save.

Important

Use strong passwords that combine uppercase and lowercase letters, numbers, and symbols. Weak passwords don't mix these elements. Passwords should be 8 or more characters in length. Make sure the CAPS LOCK key is off and use correct capitalization. Passwords are case-sensitive.

Note If cell formatting and hidden properties were previously protected by using the Format Cells or Conditional Formatting dialog boxes, they remain protected, but you can only modify options in these dialog boxes by using Excel for Windows. If you applied conditional formatting before you protected the worksheet, the formatting continues to change when a user enters a value that satisfies a different condition.

ActiveX controls, form controls, shapes, charts, SmartArt, Sparklines, Slicers, Timelines, and so on, are already locked when you add them to a spreadsheet. But the lock works only when you enable sheet protection. For more information, see Protect controls and linked cells on a worksheet.

Pausing protection turns off protection for the current editing session while maintaining the protection for other users in the workbook. For example, you can pause protection to edit a locked range but maintain protection for other users.

This is a password protected sheet. It means you can not modify the sheet, you will see a lock on it. If you want to password protect the whole file, check this out:

Your earlier comment, you are asking about populating the Excel file itself. That is a whole other question, and, should probably come before you protect the file! Protecting the file should be the last step.

Just one thing I would like to know. I also want to populate data into this password protected file using power automate. So the step which you had mentioned, after that if I use 'create table' connector, then 'add row into table' connector will data get populated in this password protected file?

Step 1) In a SharePoint Library (or in OneDrive, doesn't matter, both count as "SharePoint"), Create an Excel template where you can host your script. (Can just be a plain ole' Excel file. I just called mine ExcelScripts so I'd know what I made it for. Has no content.)

Script Location, Script Library, and Script refer to your Template. You will find that your *.osts file will appear in the same directory as where ever you saved your Template (unless you move the script, of course.)

When sharing your worksheets with other people or sending your Excel files outside of your organization, you may want to prevent other users from changing cells that shouldn't be changed, and also from moving or deleting important data in your worksheet or workbook.

Worksheet protection in Excel is not a security feature. It's is not actually intended to prevent people from accessing data in a password-protected worksheet. Why? Because Microsoft Excel uses a very simple encryption algorithm for worksheet protection. Even when you protect your Excel worksheet with a password, that password is very easy to break.

In older versions (below Microsoft Excel 2010), it doesn't even matter how long and complex your password is. Anyone who has at least some basic knowledge of VBA can crack it in minutes (here's an example of the VBA code that easily cracks passwords in Excel 2010 and lower).

The recent versions of Excel use more sophisticated methods of sheet protection, but they are also vulnerable and can be unlocked without knowing a password. In other words, if someone really wants to get access to a protected sheet, they will.

So, does this mean that Excel worksheet protection is absolutely pointless? Not at all! It makes sense to lock Excel sheets to avoid accidental changes in the sheet contents. A common example is Locking formula cells to prevent inadvertent erasure or modification of formulas.

Or, click the Protect Sheet button on the Review tab, in the Changes group.In the Protect Sheet dialog window, do the following:To password protect your Excel sheet, type a password in the corresponding field. Be sure to remember the password or store it in a safe location because you will need it later to unprotect the sheet.If the worksheet protection is nothing more than a precaution against accidental modification of the sheet contents by yourself or by the members of your local team, you may not want to bother about memorizing the password and leave the password field empty. In this case, unprotecting the sheet takes just a single click on the Unprotect Sheet button on the ribbon or in the sheet tab's right-click menu.Select the actions you allow the users to perform.By default, the following 2 options are selected: Select locked cells and Select unlocked cells. If you leave only these two options selected, the users of your sheet, including yourself, will be able only to select cells (both locked and unlocked).To allow some other actions such as sorting, filtering, formatting cells, deleting or inserting rows and columns, check the corresponding boxes.If you don't check any action, users will only be able to view the contents of your Excel sheet.Click the OK button.The Confirm Password dialog box will pop-up prompting you to retype the password so that an accidental misprint won't lock your Excel sheet forever. Retype the password and click OK. Done!How to unprotect Excel sheetAs you have just seen, it's very easy to password protect a sheet in Excel. Unprotecting a spreadsheet is even easier, provided that you know the password. Though, unlocking an Excel spreadsheet without password is no big deal either :)

If the worksheet was not protected with password, clicking the Unprotect Sheet button is all it takes to unlock the sheet.

How to unprotect Excel sheet without passwordAs mentioned in the beginning of this tutorial, Excel worksheet protection is quite weak even in the recent versions of Excel. If you need to edit a password protected sheet but you cannot remember the password, try to unlock that Excel spreadsheet by using one of the following methods.

Note. The Windows option is not available (greyed out) in Excel 2013 and higher, as shown in the screenshot above. It is because Microsoft introduced the Single Document Interface in Excel 2013, where each workbook has its own top-level window that can be minimized, restored, and closed.

Important note! Protecting the workbook structure should not be confused with workbook-level password encryption that can prevent other users from opening or/and modifying your workbook. If you are interested in this level of workbook protection, check out the next sections of this tutorial.

If you store your workbooks in a shared location such as a company local network, and you want to prevent other users from viewing your Excel files, you can encrypt your workbook with password that won't even let other people open it.

Tip. In addition to password-protection, you can secure your Excel files further by using the BitLocker Drive Encryption, which is available in the Ultimate and Enterprise editions of Windows Vista and Windows.

Tip. If you want to protect your Excel file both from modifying and opening, type the passwords in the Password to open and Password to modify boxes. It can be the same password of two different ones.

This is how you can protect an Excel sheet and lock the entire workbook from changing or opening. You can also protect a worksheet from changing by making it very hidden. Sometimes you may not want to go that far and rather lock only certain cells in your sheet. And this is exactly what we are going to discuss in the next article.

I thank you for reading and hope to see you on our blog next week.
