Save your work whenever you do something you'd hate to have to do again.
Assigning values to a workbook's properties makes it easier to find your workbook using the Windows search facility.
Be sure to give your worksheets descriptive names.
If you want to use a worksheet's data in another workbook, you can send a copy of the worksheet to that other workbook without deleting the original worksheet.
You can delete a worksheet you no longer need, but you can also hide a worksheet in the workbook. When you need the data on the worksheet, you can unhide it.
You can save yourself a lot of bothersome cutting and pasting by inserting and deleting worksheet cells, columns, and rows.
