There are several ways to simplify your formulas.

The first is to use named ranges within your formulas.

Finally, instead of using complicated, nested IF formulas, you could use alternative functions.

An Excel worksheet with an image inserted and the Compress Pictures dialog box open. In the dialog box, ‘Apply Only To This Picture’ is checked and the ‘Email (96 ppi)’ option is highlighted. Finally, the ‘OK’ button is selected.

Having blank rows and columns increases your workbook’s file size and can delay Excel’s calculation processes.

Limit Changing Values

Certain functions in Excel change the value they produce any time Excel recalculates in your spreadsheet.

These are called volatile functions.

Seven columns and five rows of random numbers between 1 and 10 in Excel, calculated using the RANDBETWEEN function.

Other examples of volatile functions include =NOW, =RANDBETWEEN, =RANDARRAY, =OFFSET, and =INDIRECT.

The obvious way to limit the processing impact of volatile functions is to reduce their use altogether.

To do this, highlight all the numbers created by the calculation and press Ctrl+C.

An Excel worksheet with the Calculation Options drop-down open, ‘Manual’ highlighted as step 1, and ‘Calculate Sheet’ highlighted as step 2.

Then, opt for top-left cell of the random array.

Another way to prevent volatile functions from slowing down your spreadsheet is to turn off automatic calculations.

Then, when you’re ready for your volatile functions to update, click “Calculate Sheet.”

When the dialog box opens, you’ll see all the named ranges in your workbook.

In the Review tab on the ribbon, head to the Performance group and click “Check Performance.”
