Hi Rich,

To restrict access to individual users for specific tabs in an Excel spreadsheet, you can use the "Protect Sheet" feature. Here are the steps:

1. Open your Excel spreadsheet and select the tab that you want to restrict access to.
2. Click on the "Review" tab in the Excel ribbon.
3. Click on the "Protect Sheet" button in the "Changes" group.
4. In the "Protect Sheet" dialog box, check the "Protect worksheet and contents of locked cells" option.
5. Enter a password in the "Password to unprotect sheet" field. This will be the password that the user will need to enter to view the tab.
6. In the "Allow all users of this worksheet to" section, uncheck all the options except for "Select unlocked cells".
7. Click on the "OK" button to apply the protection.

Repeat these steps for each tab that you want to restrict access to. When you're done, save the Excel file and put it in the shared folder.

Now, when a user opens the Excel file and tries to access a protected tab, they will be prompted to enter the password that you set up. If they enter the correct password, they will be able to view the tab. If they enter the wrong password, they will not be able to view the tab.
