Microsoft Excel Tips and Tricks

Refer to cell in another worksheet

Reference the worksheet name like this: sheet1!C12

In the example there is a worksheet for each month of the year. To reference a value in cell E7 from the January worksheet in the February worksheet do this:

 =January!E7

Increment month by one

Easy way but not always accurate, just add the number of days to next month:

 =DATE(2009,1,15)+31

Use EDATE from Analysis Toolpak (Tools>Add-ins and check Analysis Toolpak)

 =EDATE(A1,1)

With the Date function

 =DATE(YEAR(A1),MONTH(A1)+1,DAY(A1))
