VBA: Excel Automation using VBA - excel

Question

I have written multiple scripts in VBA for multiple Buttons in an excel sheet to automate a process for the same. All I want is for someone to review my code and critic its cleanliness. It would be very helpful to have suggestions on how to make the code cleaner and optimize the process.
Private Sub CommandButton1_Click()
