Help! Why won’t my Excel formula calculate?!

Note: These instructions are based off Excel 2010 but are applicable for Excel 2007 through Excel 2013 (Office 365).

Has someone sent you a spreadsheet or perhaps you’re working on one and all of a sudden your formulas look like formulas and won’t calculate? Here are the top solutions I have come across for fixing this common error.

1. Cell text formatting is set to “Text” – If the formatting of the cell has been set to Text instead of General or some other format, the cell will not calculate because it assumes that anything in the cell is text and not a formula. Change the formatting of the cell by pulling down on the drop down in the Number section on the Home tab of the menu ribbon





2. Show Formulas (Ctrl + ~) has been selected / pressed – If the Show Formulas option has been selected, calculations will show their full formula and not show the calculated results. To toggle back and forth, you can either use the hotkey combo Ctrl + ~ or select/deselect the Show Formulas option in the Formula Auditing section (I highly recommend learning to use all tools in this section when troubleshooting Excel problems!) on the Formulas tab of the menu ribbon.



3. An apostrophe (‘) has been placed before the equals (=) sign – Typically someone will have done this on purpose, however placing an apostrophe before a formula will make the cell mimic the first solution listed above where the cell formatting is set to Text. Remove the apostrophe to force the cell to calculate.



4. Automatic calculation of the worksheet / cell has been turned off – If you’ve been sent an Excel sheet that’s very large, sometimes people will turn off automatic calculations so that the spreadsheet doesn’t break your computer upon opening it. To turn on or off automatic calculations within your worksheet, click on the pull down menu of the Calculation Options in the Calculation section of the Formulas tab on the ribbon bar. Alternatively, this setting can be reached by going to the File tab, selecting Options, going to the Formulas tab and then setting the Calculations options there.

Hope this helps when you get stuck! I would appreciate hearing if anyone has come across other solutions to this common complaint?

Excel: How to use the INDIRECT function – Example

I received a request for a follow-up post to my last post on how to use the INDIRECT function in Excel. The request was to create a sample table showing a potential setup and use of it.

The best use I’ve found for the INDIRECT function is to build dashboards. You can have all your data stored on one sheet and then use INDIRECT formulas in combination with others to pull over only the data you want in a quick and easy manner.

In the picture below, there are two sample tables. The one on the top left is my “Original Data Table” which could be stored on any tab. The “INDIRECT Table” on the right uses INDIRECT formulas to pull over the data from the first, original table.

Remember that the INDIRECT formula takes in a text string and converts it to a cell reference. In this case, I put my column references as table headers and my row references as row IDs for my INDIRECT table. In this second picture, you can see how I combine the column reference & row reference in my INDIRECT formula to create a formula that is easily copied over to all the other cells in my table.

With properly setup column & row references, I need only write a single INDIRECT formula to pull over all my data in the correct order. I could just have easily made it skip every other row or skip a couple of columns, or even reorder the columns or rows by reordering my column & row references. My INDIRECT formula wouldn’t have to change at all!

Hope this helps! Let me know if you have any further questions.

Thanks!

Excel: How to use the INDIRECT function

The Excel INDIRECT function is useful for displaying data in another cell by passing it text strings to tell it where the value is.

The syntax for the Indirect function is as follows:

INDIRECT(ref_text,[a1])

Where:

ref_text is a text reference to another cell & [a1] is a logical value that specifies what type of reference style ref_text is using.

In excel you have two types of cell reference styles:

1. A1 style is where each row has a number and each column has a letter (the default view in excel).
2. R1C1 style is where each row has a number and each column has a number.

A1 is indicated by [a1] = “TRUE”, R1C1 is indicated by [a1] = “FALSE” in the INDIRECT formula.

For example in order to display a specific column of data in a given row (in this example, row 7), the following function is used:

=INDIRECT($B$1&$A7,TRUE)

The first argument, $B$1&$A7 concatenates the values in cell B1 & A7 together to create a text statement of where the data that needs to be displayed is stored. In this case B1 = “Data!B”, A7 = 3 so the final result is “Data!B3” so the value displayed in the cell is the value on the Data tab in the B3 cell.

Column A now displays the row of the data for that particular project on the “Data” tab.

Hope you find this useful!

Excel: Formula Auditing – how to troubleshoot #N/A or #REF errors?

Excel comes with a handy tool called the “Formula Auditing tool” located on the Ribbon under the “Formulas” section under “Formula Auditing”.

(Click to Enlarge)

1. The Trace Precedents tool shows you visually which cells are used by the selected cell in it’s formula.
2. The Trace Dependents tool shows you visually which cells are used by the selected cell in it’s formula.
3. The Evaluate Formula tool walks you through the formula in the selected cell so you can see how it’s calculating the formula. If there is an error, this is a handy way of figuring out where the calculation goes wrong so you can potentially fix it.
