Sum All Sheets

You need to total numbers on Jan Feb Mar ... Dec

So far, you have a workbook with 12 worksheets, one for each month. All of the worksheets have the same number of rows and columns. You want a Summary worksheet in order to total January through December.

The formula is =SUM(January:December!B4).

I make sure to never put spaces in my worksheet names. If you do use spaces, the formula would have to include apostrophes around the sheet names:

=SUM('Jan 2018:Mar 2018'!B4)

Thanks to Othneil Denis for suggesting 3D formula and Olga Kryuchkova for suggesting Group mode.

Excel Dynamic Arrays Straight to the Point

The new Dynamic Array Functions are just one side-effect of an effort to completely rewrite the Calculation Engine in Excel. Joe McDaid and the rest of the CALC team have the laid the groundwork for all future functions in Excel. Yes, the first crop of SORT, SORTBY, FILTER, UNIQUE, SEQUENCE and RANDARRAY are awesome and powerful, but they are just the first of many new functions that will come to Office 365 over the coming years.
