Allow Groups to Expand/Collapse While Spreadsheet Is Password Protected

What This VBA Code Does
Unfortunately when password protecting your worksheets, there is no option to check that will enable you to allow users to use the expand/collapse buttons for cell groupings. The only way to carry out such functionality is to run a VBA macro.
The key to getting this functionality is setting the UserInterfaceOnly protection property to TRUE and then enabling the ability to expand/collapse row/column groupings. This code only needs to be run once per sheet. Afterward, you can password protect your sheet manually (knowing that the outlines feature will always be functional when sheet protection is enabled).
Change ActiveSheet Protection Settings
Here is the code you will need to run to enable the outline buttons to work on your currently selected spreadsheet tab.
Sub EnableOutliningWithProtection()
'PURPOSE: Allow Outline functionality while Sheet is Protected
'SOURCE: www.TheSpreadsheetGuru.com/the-code-vault
'Password Protect Current Sheet
ActiveSheet.Protect Password:="", UserInterfaceOnly:=True
'Enable Group Collapse/Expand Capabilities
ActiveSheet.EnableOutlining = True
'Unprotect Sheet
ActiveSheet.Unprotect ""
End Sub
Change Every Sheet In ActiveWorkbook
As an alternative, you can run the following code to run on every sheet in your current workbook. Note that if you create new worksheets in the future, you will need to run this code again so that the new sheet(s) protection settings are changed as well.
Sub EnableOutliningWithProtection_AllSheets()
'PURPOSE: Allow Outline functionality during Protection in all Sheets
'SOURCE: www.TheSpreadsheetGuru.com/the-code-vault
Dim sht As Worksheet
'Loop through each Worksheet in ActiveWorkbook
For Each sht In ActiveWorkbook.Worksheets
'Password Protect Current Sheet
sht.Protect Password:="", UserInterfaceOnly:=True
'Enable Group Collapse/Expand Capabilities
sht.EnableOutlining = True
'Unprotect Sheet
sht.Unprotect ""
Next sht
End Sub
Using VBA Code Found On The Internet
Now that you’ve found some VBA code that could potentially solve your Excel automation problem, what do you do with it? If you don’t necessarily want to learn how to code VBA and are just looking for the fastest way to implement this code into your spreadsheet, I wrote an article (with video) that explains how to get the VBA code you’ve found running on your spreadsheet.
Getting Started Automating Excel
