php editor Xiaoxin introduces you 3 methods to set up PPT file protection. In today's network environment where information is transmitted frequently, protecting personal and confidential information is crucial. By setting password protection, restricting editing permissions, and using encryption methods, you can effectively ensure that your PPT files are not accessed or modified by unauthorized persons and improve data security.
1. If we don’t want PPT to be opened at will, we can set an opening password.
First, open the PPT and click the [File] option, and then click [Protect Presentation] - [Encrypt with Password] on the right side of [Information].
In the pop-up dialog box, enter the password you want to set, click [OK], confirm the password again, and the password for opening PPT will be set.
2. If the PPT can be opened at will but does not want to be changed, we can set restrictions on editing of the PPT. In this way, the other party will not be able to edit the PPT, nor can they copy, print, etc.
First, open the PPT and click the [File] option, then click [Save As], and select the save path after saving on the right.
In the pop-up dialog box, click [General Options] under the [Tools] list below.
After a new dialog box pops up, enter the password you want to set in the [Modify permission password] column, and then click [OK].
After setting it up, when you reopen the PPT, you will be prompted to enter a password. Without a password, it can only be opened in "read-only mode". PPT in "read-only mode" cannot be edited.
3. In addition to the above two methods, we can also set watermarks on PPT to further protect PPT ownership.
First, open PPT and click [View]-[Slide Master] on the toolbar above.
Then select the first slide of the master slide on the left.
After selecting, return to the upper toolbar and select [Insert]-[Text Box].
At this time, you can enter text in the text box and edit the watermark content you want. You can adjust the size, font, color, and position. Icons can also be inserted.
After editing the watermark content, click [Slide Master]-[Close Master View] on the toolbar above.
At this time, we can see that the original PPT has added watermark content. Subsequently created pages will also be automatically added with this watermark.
Finally, I would like to remind my friends that for the first two ways of adding passwords, you must remember the passwords or save them.
If you accidentally forget your password, you cannot retrieve it through PPT. In this case, we can use other tools to solve the problem.
Similar tools such as Pepsi Niu PPT password recovery tool. If you forget to open the password, you can select the [Retrieve Password] module in the tool. If you forget the permission password, select the [Unrestriction] module.

Use formula conditional formatting to handle overflow arrays in Excel Direct formatting of overflow arrays in Excel can cause problems, especially when the data shape or size changes. Formula-based conditional formatting rules allow automatic formatting to be adjusted when data parameters change. Adding a dollar sign ($) before a column reference applies a rule to all rows in the data. In Excel, you can apply direct formatting to the values or background of a cell to make the spreadsheet easier to read. However, when an Excel formula returns a set of values (called overflow arrays), applying direct formatting will cause problems if the size or shape of the data changes. Suppose you have this spreadsheet with overflow results from the PIVOTBY formula,

Excel Overflow Range Operator (#) enables formulas to be automatically adjusted to accommodate changes in overflow range size. This feature is only available for Microsoft 365 Excel for Windows or Mac. Common functions such as UNIQUE, COUNTIF, and SORTBY can be used in conjunction with overflow range operators to generate dynamic sortable lists. The pound sign (#) in the Excel formula is also called the overflow range operator, which instructs the program to consider all results in the overflow range. Therefore, even if the overflow range increases or decreases, the formula containing # will automatically reflect this change. How to list and sort unique values in Microsoft Excel
