Imagine if you have hundreds of employees working under you and you need to know about the details of only twenty employees’ salaries and their departments. It is impossible to do such a thing by just pointing out, that’s where Conditional formatting comes in handy. Thus, it becomes imperative to know what is conditional formatting in excel.

Conditional formatting is a feature that allows us to sort the only cells that match according to the condition that we provide. It is mostly used to highlight or emphasise certain data and to visualize the data using bars, scales, etc. 

Let’s get started now to see what is conditional formatting in excel with example.

Select Home >> Conditional Formatting tool located in the Styles group, which has further options. Now click on the arrow.

There are options like:

1. Highlight Cells Rules

2. Top/Bottom Rules

3. Data bars

4. Color Scales

5. Icon sets.

Highlight Cells Rules

Highlight Cells Rules option is used to highlight only those cells that satisfy the condition. These are the part of preset rules.

Let’s take a dataset as a common example and highlight them concerning the types. Here let’s consider the range B2: D8.

There are categories under this option, such as:

Greater than

The option lets you highlight the numbers that are greater than the number that is set. 

Consider that we need the numbers greater than 362 to be highlighted. 

Some options can be selected for setting the colour to be highlighted.

Output:

Less than

This option lets you highlight only the values that are less than the specified number 40.

Between

This option can be used to highlight only the numbers that lie between two specified values.

Equal to

The option is used to highlight only the values that are equal to the given value.

Text that contains

The option lets you highlight just the words that you specify.

A date occurring

This option lets you highlight.

Duplicates

The option lets you highlight the cells that have a number repeated or the numbers that are not repeated depending on the option selected.

Example: If we have the value 194, the cells that have 194 as its value will be highlighted if we click on the option Duplicate and vice versa if we click on the option Unique.

Top / Bottom Rules

Considering you want to know about the best or worst values of a huge dataset, you can use this option. Top/ Bottom rules are another set of preset rules that allow you to input a specific number, and the output would be according to the range you previously specified.

• Top 10 items
• Top 10% items
• Bottom 10 items
• Bottom 10% items
• Above Average
• Below Average

 Let’s take the same set of data now. The range is B2:D8.

Top 10 items

The option lets you highlight the top 10 out of the selected cells. However, the number can be changed. By default, though, it is 10 in all the categories.

Bottom 10 items

This is used to highlight the cells that have the least values in the selected cells.

Assume that we have values from 0-1000.

Top 10% items

The option highlights the top values of the given range of cells. The top 10% will highlight the cells having values from 900-1000.

Bottom 10% items

The option highlights the cells having values of the bottom 10%.

Above Average

The Excel calculates the average value of the selected range and will highlight only those cells that are above the average value. Consider an average value 42.5, then the cells having values above this value will be highlighted.

Below Average

This option follows the same rules, but the cells having values lower than the average value will be highlighted, and that’s the only difference.

Data Bars

The data bar is an option that shows the value of the cells selected in the form of data bars. These data bars vary in the size depending upon the value in the selected cells. Example, for a higher value, the bar will be longer, and for smaller values, it would be shorter. 

We could see that the cells in column B have different kinds of data bars. For numbers such as 65, 173, the data bar is shorter compared to the data bars for numbers such as 387, 496, etc. 

Color Scales

The color scale is an option used to indicate the different set of values or cells with different types of options. In any option, the top row of color indicates the larger value and the last row of color indicates the smaller value. Here let’s take the third set.

Icon Sets

The icon sets are different kinds of highlighters that can be used to interpret data easily without having to look keenly.

The values which are less than or equal to 200 turns to red and others turn to green. 

Other Important Features

There are other three options in the conditional formatting drop-down list. 

New Rule

A new rule option lets you reset all the values or conditions that you have given in any of the options in a separate window. Using this you could do conditional formatting using formula too. The steps are as follows:

• Click on Use a formula to determine which cells to format.
• Enter the cell value by clicking and dragging the column where you have to use the formula. We cannot take $C$2 because only that cell will be included since we need the whole column, we would use $C2. 
• Click Format >> Fill >> OK and again OK.

Clear Rules

Clear Rules again contain two more options, and they are Clear from the selected cells and Clear from the Entire sheet. They are used to clear the entire rule either from the rows that are selected or from the entire sheet depending upon the option you choose.

Manage Rules

Manage Rules provide you a different window just like in the New Rules option which lets you edit or delete any rules.

What is the use of conditional formatting?
