I have a curent Excel file that I need to add an additional month of data by adding another worksheet to the workbook. The problem is it must look the same but only the numbers change. Its hard for me to re-create in Excel because Im not that good with excel(so I just copy and paste). Is there a way that I could automate my current process of(copying) the worksheet over to a new one and change the numbers within it? I tried to use Spreadsheet-WriteExcel but it opens a new file over writing my current one. Thanks in Advance, Fue....
