It can be frustrating, even problematic, when your Excel formulas are not working. We use formulas in our Excel spreadsheets to automatically calculate values for us, or concatenate Excel values, and many of those formulas rely on data that is in several cells. Ideally, when we update the values in those cells, the information displayed by our formulas will update as well.
But calculation operations can be resource intensive, particularly when working with large spreadsheets, so some Excel users will elect to switch their spreadsheets to manual calculation. This is fine when you are the one creating the spreadsheet, and know that you will need to manually calculate your formulas when you are done making changes to your data. But spreadsheets get shared with others, who might not be aware that those spreadsheets need a little more interaction. Our guide below will show you how to get your formulas to start working by switching to automatic calculation, or by telling Excel to calculate your formulas now.
Excel Formulas Not Working – Excel 2013
The steps in this article will assume that you have previously entered an Excel formula into a cell, but that the result of that formula is not updating as you make changes to the cells that the formula references.
Step 1: Open the file in Excel 2013.
Step 2: Click the Formulas tab at the top of the window.
Step 3: Click the Calculation Options button in the Calculation section of the ribbon, then click the Automatic option.
Note that your formula value should update after you click the Automatic option. You an also force your formulas to update by clicking the Calculate Now button.
If the formula that you entered into the cell never calculated, then the cell might be formatted as text. You can change this by right-clicking the cell, clicking Format Cells, then selecting General. Note that you might need to cut and paste the formula back into the cell to get it to calculate.
Important note – If you save a file with multiple worksheet tabs selected, this can cause the formula setting to switch from automatic to manual. If you find that the calculation setting in a file keeps changing, it might be a good idea to check that the file is not being saved with grouped worksheets.
Excel offers a number of other formulas that can interact with your data in ways other than mathematical operators. For example, you can combine two columns with a formula.
