When working with VBA code in Excel, it is important to document any changes that are made to the code. This can be done by adding comments to the code itself, or by creating a separate document that outlines the changes that have been made. Comments can be added to VBA code by using the ''' character. For example:
''' This is a comment
Comments can be added to the end of a line of code, or on their own line. When adding comments to the end of a line of code, make sure to add a space between the ''' character and the start of the comment. Otherwise, the comment will become part of the code itself.
It is also possible to create a separate document that outlines the changes that have been made to VBA code. This document can be created in any text editor, and should include the date of each change, a description of the change, and the name of the person who made the change. This document can then be saved in a central location, such as a shared network drive, so that it can be accessed by all members of the team.
