Numbers Ignoring Excel Protection How To Consistently Make

However, the workbook wound need a way to decrypt it every time it is needed to calculate a worksheet.

The workbook has only a single worksheet, and she needs to protect columns E and J so they cannot be changed, unless the user knows a particular password.

Excel displays the Protect Sheet dialog box.

See Figure 2.).

If someone knows the password you used in step 15, however, they can unprotect the worksheet (the proper control is on the Review tab of the ribbon) and make any changes they want.

If someone does make changes in this way, they will need to reapply the protection (steps 12 through 17) prior to saving the workbook.

If they dont, then the next time the workbook is open, the worksheet remains unprotected and anyone can change the contents of columns E and J.

For instance, you might rethink how your data is put together and, perhaps, move the contents of columns E and J to another worksheet or even to another workbook.

You can then protect that information and simply reference it within the current worksheet.

This new tool, which allows you to password-protect ranges of cells, requires a variation on the steps presented earlier in this tip.

The steps will be many, but it does provide for a more flexible way of dealing with the protection issue.

The range now appears in the Allow Users to Edit Ranges dialog box.

This should not be the same password you used in step 17 and step 19; it should be different.

As someone is using a worksheet protected in this manner, when they try to modify a cell in columns E or J, they are asked for a password.

If they supply the correct password (this is the one that you specified in steps 17 and 19), then they can edit anything they want in columns E and J.

When the workbook is saved, exited, and reopened, then the protection is automatically reset and columns E and J can again only be edited if the password is knownthere is no need for the user to explicitly reprotect the worksheet before saving.

Plus, you never have to give out the password that you used to protect the entire worksheet.

The authors show how to consistently make the right design decisions and make the most of Excels powerful features.

Is there a way I can removed passwords from this workbook Thank you.

Robert.

What, pray tell, is its name For Bruno, short of writing a macro, I am unaware of any way to apply protection settings to two or more sheets in one go.

For Walter, yes, a determined hacker can break the Excel password protection, without venturing into the Dark Web.

I have in my possession one of several such modules that are readily available.

Information that needs that level of protection would need to be encrypted in ways that would be nontrivial to use with Excel.

Theoretically, a VBA module that used the CryptoAPI libraries to encrypt the data could be used to encrypt data within a specific range.
