I am seeking for a help. I'm a noob to Microsoft Office apps. I need to do something using excel. The issue is how can I automatic create new sheets base on my first sheet ? Can I have an excel file with 12 months of worksheets and every month with the 30/31 days of worksheets with the dates automatically generated ? I'm sorry if my question is confusing. Hopefully someone can help me and hopefully could understand what I need. I'm pleased to include the file which I need to work on as below.
