Excel Running Total Trouble

October 20, 2020

Spill functions, running total problems, and more, in this week's Excel news. Visit my Excel website for more tips, tutorials and videos, and check the index for past issues of this newsletter.

Thank you for reading the news, and you'll get the next email in two weeks, on November 3rd.

### Spill Formulas

Thanks to Dermot Balson, who sent me his Excel workbook with examples for all the new functions (dynamic arrays) in Excel for Office 365.

The examples also show how even the old Excel functions, such as OFFSET, will spill automatically, if your version of Excel supports spill functions. This formula returns 3 rows and 3 columns of data:

=OFFSET(C4,I17,0,3,3)

Another example combines the new function, SEQUENCE, with the old function, TODAY, to create a 4 row, 7 column calendar:

=SEQUENCE(4,7,TODAY())

To see more of Dermot's examples, and to get the sample file, go to the Excel Spill Functions page on my Contextures site.

### Running Total Problem

For a list on a worksheet, this formula works well to create a running total, based on the amounts in column C: =SUM(C\$2:C2)

However, if you use that formula in a named Excel table, things can go horribly wrong. For example, cell D6 had this formula: = SUM(C\$2:C6)

When a new row started, the D6 formula automatically changed to this: =SUM(C\$2:C7)

To avoid that problem, use a heading cell as the locked starting point (C\$1), and a structured table reference to the Amt cell in the current row: =SUM(C\$1:[@Amt])

You can read more about the running total problem, and download the workbook, on the Excel Sum Functions page of my Contextures site.

Halloween is just around the corner, so it's time to prepare for winter, here in Canada. We got our flu shots last week, and a new batch of masks, from a small company in Montreal. My other winter prep purchase is a weighted blanket - the Mayo Clinic says it might help with better sleep, and reducing stress. And who doesn't need that?

I'll also post any article updates or corrections there.

That's it for this week! If you have any comments or questions, send me an email.
