How to Protect/Unprotect Excel Sheet

When you share your worksheets with others or transmit Excel files outside of your business, you may wish to prohibit other users from modifying cells that should not be modified, as well as relocating or deleting key data in your worksheet or workbook. Fortunately, Excel allows you to quickly and easily lock a sheet or password protect an entire workbook to prevent inadvertent or purposeful alterations to its contents.

What do you need to know about Excel sheet protection?

Worksheet protection in Excel is not a security feature. It is not meant to prevent others from viewing data in a password-protected spreadsheet. Why? Microsoft Excel protects worksheets using a basic encryption method. Even if you use a password to safeguard your Excel spreadsheet, it is quite easy to breach. It makes no difference how lengthy or difficult your password is in earlier versions (before Microsoft Excel 2010). Anyone with even a little understanding of VBA can crack it in minutes.

Recent versions of Excel utilize more advanced techniques of sheet protection, but they are still insecure and may be opened without a password. In other words, if someone truly wishes to gain access to a protected sheet, they will. So, does this indicate that Excel worksheet protection is completely unnecessary?

Not at all! It makes logical to lock Excel sheets to prevent unintentional modifications to their contents. A popular example is locking formula cells to prevent formulae from being accidentally erased or modified.

The bottom line is to lock an Excel spreadsheet to keep other users from mistakenly tampering with your data, but never save important information in your Excel sheets.

If you want to secure the highest security protection for your Excel files, you should complete all of the following:

• Use the latest Excel versions with improved data encryption techniques.
• Protect your spreadsheets with strong passwords that contain a variety of alpha numeric characters and unique symbols.
• At that point, attempt to construct passwords as random as possible, such as using our password generator.
• Protect the workbook structure so that others cannot add, move, rename, delete, or unhide your sheets.
• To ensure workbook security, encrypt the workbook using various passwords for opening and changing.

How to protect Excel sheet

To protect a sheet in Excel, perform the following steps.

1. Right click a worksheet tab at the bottom of your screen and select Protect Sheet… from the context menu.

   Or, click the Protect Sheet button on the Review tab, in the Changes group.

2. In the Protect Sheet dialog window, perform the following:

• To password-protect your Excel sheet, enter a password in the designated box. Remember the password or keep it somewhere secure since you'll need it later to unprotect the spreadsheet.

• If the worksheet protection is only a precaution against unintentional change of the sheet contents by yourself or members of your local team, you may not want to bother learning the password and should leave the password box blank. In this situation, unprotecting the sheet is as simple as clicking the Unprotect Sheet button on the ribbon or using the right-click menu on the sheet tab.

3. Choose the activities you want your users to be able to execute.

• By default, the following two choices are selected: Select locked and unlocked cells. If you leave only these two choices chosen, all users of your sheet, including yourself, will be limited to selecting cells (both locked and unlocked).

• Check the appropriate boxes to enable additional functions like as sorting, filtering, formatting cells, and removing or adding rows and columns.

• If you do not choose any actions, users will only be able to see the contents of your Excel sheet.

• Click the Okay button.
