Excel Icon Sets conditional formatting: inbuilt and custom

The article provides detailed guidance on how to use conditional formatting Icon Sets in Excel. It will teach you how to create a custom icon set that overcomes many limitations of the inbuilt options and apply icons based on another cell value.

A while ago, we started to explorer various features and capabilities of Conditional Formatting in Excel. If you haven't got a chance to read that introductory article, you may want to do this now. If you already know the basics, let's move on and see what options you have with regard to Excel's icon sets and how you can leverage them in your projects.

Excel icon sets

Icon Sets in Excel are ready-to-use formatting options that add various icons to cells, such as arrows, shapes, check marks, flags, rating starts, etc. to visually show how cell values in a range are compared to each other.

Normally, an icon set contains from three to five icons, consequently the cell values in a formatted range are divided into three to five groups from high to low. For instance, a 3-icon set uses one icon for values greater than or equal to 67%, another icon for values between 67% and 33%, and yet another icon for values lower than 33%. However, you are free to change this default behavior and define your own criteria. Excel Icon Sets: inbuilt and custom

How to use icon sets in Excel

To apply an icon set to your data, this is what you need to do:

  1. Select the range of cells you want to format.
  2. On the Home tab, in the Styles group, click Conditional Formatting.
  3. Point to Icon Sets, and then click the icon type you want.

That's it! The icons will appear inside the selected cells straight away. Using an icon set in Excel

How to customize Excel icon sets

If you are not happy with the way Excel has interpreted and highlighted your data, you can easily customize the applied icon set. To make edits, follow these steps:

  1. Select any cell conditionally formatted with the icon set.
  2. On the Home tab, click Conditional Formatting > Manage Rules.
  3. Select the rule of interest and click Edit Rule. Customize an Excel icon sets.
  4. In the Edit Formatting Rule dialog box, you can choose other icons and assign them to different values. To select another icon, click on the drop-down button and you will see a list of all icons available for conditional formatting. Choose another icon.
  5. When done editing, click OK twice to save the changes and return to Excel.

For our example, we've chosen the red cross to highlight values greater than or equal to 50% and the green tick mark to highlight values less than 20%. For in-between values, the yellow exclamation mark will be used. A customized icon set

Tips:

  • To reverse icon setting, click the Reverse Icon Order button.
  • To hide cell values and show only icons, select the Show Icon Only check box.
  • To define the criteria based on another cell value, enter the cell's address in the Value box.
  • You can use icon sets together with other conditional formats, e.g. to change the background color of the cells containing icons.

How to create a custom icon set in Excel

In Microsoft Excel, there are 4 different kinds of icon sets: directional, shapes, indicators and ratings. When creating your own rule, you can use any icon from any set and assign any value to it.

To create your own custom icon set, follow these steps:

  1. Select the range of cells where you want to apply the icons.
  2. Click Conditional Formatting > Icon Sets > More Rules.
  3. In the New Formatting Rule dialog box, select the desired icons. From the Type dropdown box, select Percentage, Number of Formula, and type the corresponding values in the Value boxes.
  4. Finally, click OK.

For this example, we've created a custom three-flags icon set, where:

  • Green flag marks household spendings greater than or equal to $100.
  • Yellow flag is assigned to numbers less than $100 and greater than or equal to $30.
  • Green flag is used for values less than $30.

How to set conditions based on another cell value

Instead of "hardcoding" the criteria in a rule, you can input each condition in a separate cell, and then refer to those cells. The key benefit of this approach is that you can easily modify the conditions by changing the values in the referenced cells without editing the rule.

For example, we've entered the two main conditions in cells G2 and G3 and configured the rule in this way:

  • For Type, pick Formula.
  • For the Value box, enter the cell address preceded with the equality sign. To get it done automatically by Excel, just place the cursor in the box and click the cell on the sheet. Define the icon set conditions based on another cell.

Excel conditional formatting icon sets formula

To have the conditions calculated automatically by Excel, you can express them using a formula.

To apply conditional formatting with formula-driven icons, start creating a custom icon set as described above. In the New Formatting Rule dialog box, from the Type dropdown box, select Formula, and insert your formula in the Value box.

For this example, the following formulas are used:

  • Green flag is assigned to numbers greater than or equal to an average + 10:

    =AVERAGE($B$2:$B$13)+10

  • Yellow flag is assigned to numbers less than an average + 10 and greater than or equal to an average - 20.

    =AVERAGE($B$2:$B$13)-20

  • Green flag is used for values lower than an average - 20.
Create a conditional formatting icon set using a formula.

Note. It's not possible to use relative references in icon set formulas.

Excel conditional format icon set to compare 2 columns

When comparing two columns, conditional formatting icon sets, such as colored arrows, can give you an excellent visual representation of the comparison. This can be done by using an icon set in combination with a formula that calculates the difference between the values in two columns - the percent change formula works nicely for this purpose.

Suppose you have the June and July spendings in columns B and C, respectively. To calculate how much the amount has changed between the two months, the formula in D2 copied down is:

=C2/B2 - 1 The percent change formula to compare the values in the two columns

Now, we want to display:

  • An up arrow if the percent change is a positive number (value in column C is greater than in column B).
  • A down arrow if the difference is a negative number (value in column C is less than in column B).
  • A horizontal arrow if the percent change is zero (columns B and C are equal).

To accomplish this, you create a custom icon set rule with these settings:

  • A green up arrow when Value is > 0.
  • A yellow right arrow when Value is <=0 and >=0, which limits the choice to zeros.
  • A red down arrow when Value is < 0.
  • For all the icons, Type is set to Number.

At this point, the result will look something like this: Excel icon set to compare 2 columns

To show only the icons without percentages, tick the Show Icon Only checkbox. Compare two columns using only the icons.

How to apply Excel icon sets based on another cell

A common opinion is that Excel conditional formatting icon sets can only be used to format cells based on their own values. Technically, that is true. However, you can emulate the conditional format icon set based on a value in another cell.

Suppose you have payment dates in column D. Your goal is to place a green flag in column A when a certain bill is paid, i.e. there is a date in the corresponding cell in column D. If a cell in column D is blank, a red flag should be inserted.

To accomplish the task, these are the steps to perform:

  1. Start with adding the below formula to A2, and then copy it down the column:

    =IF($D2<>"", 3, 1)

    The formula says to return 3 if D2 is not empty, otherwise 1. Formula to identify blank and non-blank cells

  2. Select the data cells in column A without the column header (A2:A13) and create a custom icon set rule.
  3. Configure the following settings:
    • Green flag when the number is >=3.
    • Yellow flag when the number is >2. As you remember, we do not really want a yellow flag anywhere, so we set a condition that will never be satisfied, i.e. a value less than 3 and greater than 2.
    • In the Type dropdown box, pick Number for both icons.
    • Select the Icon Set Only checkbox to hide the numbers and only show the icons.

The result is exactly as we were looking for: the green flag if a cell in column D contains anything in it and the red flag if the cell is empty. Configure an Excel icon sets based on another cell.

Excel conditional formatting icon sets based on text

By default, Excel icon sets are designed for formatting numbers, not text. But with just a little creativity, you can assign different icons to specific text values, so you can see at a glance what text is in this or that cell.

Suppose you've added the Note column to your household spendings table and want to apply certain icons based on the text labels in that column. The task requires some preparatory work such as:

  • Make a summary table (F2:G4) numbering each note. The idea is to use a positive, negative, and zero number here.
  • Add one more column to the original table named Icon (it's where the icons are going to be placed).
  • Populated the new column with a VLOOKUP formula that looks up the notes and returns matching numbers from the summary table:

    =VLOOKUP(C2, $F$2:$G$4, 2, FALSE)

    Summary table  and VLOOKUP formula

Now, it's time to add icons to our text notes:

  1. Select the range D2:D13 and click Conditional Formatting> Icon Sets > More Rules.
  2. Choose the icon style you want and configure the rule as in the image below: An icon set rule for text values
  3. The next step is to replace the numbers with text notes. This can be done by applying a custom number format. So, select the range D2:D13 again and press the CTRL + 1 shortcut.
  4. In the Format Cells dialog box, on the Number tab, select the Custom category, enter the following format in the Type box, and click OK:

    "Good";Exorbitant";"Acceptable"

    Where "Good" is the display value for positive numbers, "Exorbitant" for negative numbers, and "Acceptable" for 0. Please be sure to correctly replace those values with your text.

    This is very close to the desired result, isn't it? Apply a custom format for positive numbers, negative numbers, and zeros.

  5. To get rid of the Note column, which has become redundant, copy the contents of the Icon column, and then use the Paste Special feature to paste as values in the same place. However, please keep in mind that this will make your icons static, so they won't respond to changes in the original data. If you are working with an updatable dataset, skip this step.
  6. Now, you can safely hide or delete (if you replaced the formulas with calculated values) the Note column without affecting the text labels and symbols in the Icon column. Done! Conditional formatting icon sets for text values

Note. In this example, we've used a 3-icon set. Applying 5-icon sets based on text is also possible but requires more manipulations.

How to show only some items of the icon set

Excel's inbuilt 3-icon and 5-icon sets look nice, but sometimes you may find them a bit inundated with graphics. The solution is to keep only those icons that draw attention to the most important items, say, best performing or worst performing.

For example, when highlighting the spendings with different icons, you may want to show only those that mark the amounts higher than average. Let's see how you can do this:

  1. Create a new conditional formatting rule by clicking Conditional formatting > New Rule > Format only cells that contain. Choose to format cells with values less than average, which is returned by the below formula. Click OK without setting any format.

    =AVERAGE($B$2:$B$13) Create a conditinal formatting rule with no format set for values less than average.

  2. Click Conditional Formatting > Manage Rules…, move up the Less than average rule, and put a tick into the Stop if True check box next to it.

As a result, the icons are only shown for the amounts that are greater than average in the applied range: The icons are only shown for the amounts greater than average.

How to add custom icon set to Excel

Excel's built-in sets have a limited collection of icons and, unfortunately, there is no way to add custom icons to the collection. Luckily, there is a workaround that allows you to mimic conditional formatting with custom icons.

Method 1. Add custom icons using Symbol menu

To emulate Excel conditional formatting with a custom icon set, these are the steps to follow:

  1. Create a reference table outlining your conditions as shown in the screenshot below.
  2. In the reference table, insert the desired icons. For this, clicking the Insert tab > Symbols group > Symbol button. In the Symbol dialog box, select the Windings font, pick the symbol you want, and click Insert.
  3. Next to each icon, type its character code, which is displayed near the bottom of the Symbol dialog box. Insert custom icons from the Symbols menu.
  4. For the column where the icons should appear, set the Wingdings font, and then enter the nested IF formula like this one:

    =IF(B2>=90, CHAR(76), IF(B2>=30, CHAR(75), CHAR(74)))

    With cell references, it takes this shape:

    =IF(B2>=$H$2, CHAR($F$2), IF(B2>=$H$3, CHAR($F$3), CHAR($F$4)))

    Copy the formula down the column, and you will get this result: A custom icon set based on a formula

Black and white icons appear rather dull, but you can give them a better look by coloring the cells. For this, you can apply the inbuilt rule (Conditional Formatting > Highlight Cells Rules > Equal To) based on the CHAR formula such as:

=CHAR(76)

Now, our custom icon formatting looks nicer, right? Custom icons in colored cells

Method 2. Add custom icons using virtual keyboard

Adding custom icons with the help of the virtual keyboard is even easier. The steps are:

  1. Start by opening the virtual keyboard on the task bar. If the keyboard icon is not there, right-click on the bar, and then click Show Touch Keyboard Button.
  2. In your summary table, select the cell where you want to insert the icon, and then click on the icon you like.

    Alternatively, you can open the emoji keyboard by pressing the Win + . shortcut (the Windows logo key and the period key together) and select the icons there. Insert custom icons from the emoji keyboard.

  3. In the Custom Icon column, enter this formula:

    =IF(B2>=$G$2, $E$2, IF(B2>=$G$3, $E$3, $E$4))

    In this case, you need neither the character codes nor fiddling with the font type.
