automating locking of group of cells

Question

Hey Excel Nerds. I need to know if excel has this capacity. We have an excel workbook that has multiple sheets labeled as months and repeating tables on each sheet representing each day. Is there anyway that once a day is over, say midnight every night, that the table associated with that day gets locked automatically without someone manually having to lock it? I am looking to protect the sheet, but only for the parts that have passed in time since each table represents data from each day. historical data needs to be protected, which the currenty real-time day data can be entered by multiple people.&nbsp;

Hey Rajesh-S! Thanks for the response. I watched some videos on VBA Macro. I don't think I'm equipped to figure it out and make it do what I need. Can you advise about where I can get outside help on this? Much appreciated!

Rajesh_Sinha&nbsp; Hey!&nbsp; Thanks for the offer, I appreciate the help very much. I've attached a blank version of the workbook that need help with. Maybe you could use it to instruct me. Go to the Oct 2021 tab and see the tables at the very top that are labled. Each repeating row of tables represent a day in the month of October. Everyday data gets put into the empty cells by multiple people.&nbsp; At the end of the day at 11pm, I would like those tables to become locked for security reasons and continue to automatically lock as each day passes at 11pm.&nbsp; &nbsp;I've attached the workbook and a pdf showing exactly which group of cells (circled in red) that needs to be locked with each passing day. Let me know if there is a way to make this happen in VBA Macros. I am eager to have more knowledge under my belt, so again, much appreciated!

maker340&nbsp;&nbsp;This will help you, protects particular Sheet at particular TIME.&nbsp;Private Sub Workbook_Open()
Application.OnTime Now + TimeValue("11:00:00"), "ProtectMysheets"
End SubWhere ProtectMysheets is also VBA macro.&nbsp;This code has Sheet name along with Passcode.Sub ProtectMysheets()
   Sheets("Sheet1").Protect Password:="YourPassword"
   Sheets("Sheet5").Protect Password:="YourPassword"
End Sub&nbsp;You may add as many Sheets &amp; replace YourPassword with a Pass code of your choice, remember Pass code is Case sensitive.&nbsp;Suggested to protect entire sheet instead of TABLE since sheet has many Tables.&nbsp;But if you are disparately looking to lock the Table then use the following VBA code, lock Range of cells, you need to use the cell range to lock particular Table.&nbsp;&nbsp;Private Sub workbook_open()

Dim systime As String
Dim mypassword As String

systime = Format(Now, "hh:mm:ss")
mypassword = "abcd"

If TimeValue(systime) &gt; TimeValue("11:00:00") Then

With ThisWorkbook.ActiveSheet

.Unprotect Password:=mypassword
    .Range("B2:F40").Locked = True
    .Protect Password:=mypassword

End With

ThisWorkbook.Save

End If

End Sub&nbsp;Where Pass code abcd, Time 11:00:00 &amp; Range for Table B2:F40 are editable.&nbsp;
