## 1. How to highlight differences in price lists

I am now going to show you how to quickly compare two tables using Conditional Formatting (CF). I am going to compare two price lists from the year 2010 and year 2011.

I have two types of data set layouts I want to share a solution for, basic dataset layout shown above and a two-index layout.

To make things more authentic in my examples, products in price list 2011 are not sorted in the same way as 2010. New products are alsoÂ introduced.

It is quite common that price lists are huge and a total mess. Excel is the perfect tool for finding the differences between datasets.

A requirement for these conditional formatting formulas to work, is that column and row headers have identical spelling.

The same letter capitalization is not required.

### 1.1Basic dataset layout

I have two worksheets, in this example, named *2010* and *2011.*Â They both contain a category, product, and a price column.

Color |
Description |

Yellow | A new item in the list. |

Green | Price increase. |

Red | Price decrease. |

There are three different CF formulas applied to cell range D3:D14, each coloring a cell based on a condition.

Two or more CF formulas can't color cell at the same time, the logical expressions I built can't all be true at the same time.

#### RedÂ Conditional Formatting formula

The red CF formula compares the value in column D based on category value and product value with the corresponding product, category and price in worksheet 2010. If the value in column D is smaller the cell is highlighted red.

The COUNTIFS function returns an array that indicates the position of the corresponding price. The following explanation is for cell D12, see picture above.

COUNTIFS($B12, 2010'!$B$3:$B$12, $C12, 2010'!$C$3:$C$12) returnsÂ {0; 0; 0; 0; 0; 0; 1; 0; 0; 0}.

The MATCH function returns the position of a given value in the array.

MATCH(1,COUNTIFS($B12, 2010'!$B$3:$B$12, $C12, 2010'!$C$3:$C$12), 0)

becomes

MATCH(1,{0; 0; 0; 0; 0; 0; 1; 0; 0; 0}, 0) and returns 7. Now we know where the value we are looking for is.

$D12<INDEX(2010'!$D$3:$D$12, MATCH(1,COUNTIFS($B12, 2010'!$B$3:$B$12, $C12, 2010'!$C$3:$C$12), 0))

becomes

$D12<INDEX(2010'!$D$3:$D$12, 7)

becomes

$441.27<$450 and returns TRUE.

Cell D12 is highlighted red.

#### GreenÂ Conditional Formatting formula

The green CF formula is similar to the red CF formula except that the cell is highlighted green if the value in column D is larger than the corresponding value in worksheet 2010.

The only difference between the red and green CF formulas is the larger than and smaller than sign.

#### Yellow Conditional Formatting formula

The yellow CF formula checks if the category and product is not found in worksheet 2010, if TRUE the cell is highlighted yellow.

### Two index table

The questions I am going to answer in this article are:

- How do I find
**new products or models**compared to previous year?

- How to identify
**lowered prices**compared to previous year?

- How to identify
**higher prices**compared to previous year?

Here are the two tables together on the same worksheet.

As you can see "product E" is new for 2011 (highlighted yellow), "product A" type 4 has a lower price than the previous year 2010 (highlighted red), etc.

The colors make it very easy to spot differences.

#### New values compared to last year

The following CF formula highlights entire row yellow if it finds a new product name.

Conditional formatting formula:

It compares the product and type columns between the tables and if a value is not found the CF formula highlights the entire row yellow.

#### Find lower prices

**Conditional formatting formula:**

Cells are formatted red if the price is lower than the price in the other table.

#### Find higher prices

**Conditional formatting formula:**

Cells are formatted green if the price is higher than the price in the other table.

#### How to apply conditional formatting formula

Make sure you adjust cell references to your excel sheet.

- Select cells C11:G15
- Press with left mouse button on "Home" tab
- Press with left mouse button on "Conditional Formatting" button
- Press with left mouse button on "New Rule.."
- Press with left mouse button on "Use a formula to determine which cells to format"
- Copy and paste conditional formatting formula in "Format values where this formula is TRUE" window.
- Press with left mouse button on "Format.." button
- Press with left mouse button on "Fill" tab
- Select a color for highlighted cells.
- Press with left mouse button on "Ok"
- Press with left mouse button on "Ok"
- Press with left mouse button on "Ok"

#### Explaining find lower prices conditional formatting formula in cell C11

You can follow along, copy the CF formula and paste it in a cell.

Go to tab "Formula" on the ribbon and then press with left mouse button on "Evaluate Formula" button.

Press with mouse on the "Evaluate" button to move to the next step in the calculations.

**Step 1 - Find relative position of current row header in previous pricelist**

=INDEX($C$4:$G$7, **MATCH($B11, $B$4:$B$7, 0)**, MATCH(C$10, $C$3:$G$3, 0))<C11

The MATCH function returns the relative position of an item in an array that matches a specified value.

MATCH($B11, $B$4:$B$7, 0)

becomes

MATCH("Product A", {"Product A";"Product B";"Product C";"Product D"}, 0)

and returns 1.

**Step 2 - Find relative position of current column header in previous price list**

=INDEX($C$4:$G$7,Â MATCH($B11, $B$4:$B$7, 0), **MATCH(C$10, $C$3:$G$3, 0)**)<C11

MATCH(C$10, $C$3:$G$3, 0)

becomes

MATCH("Model 1", {"Model 1", "Model 2", ... , "Model 5"}, 0)

returns 1. Type 1 is found in position 1 in cell range C3:G3.

**Step 3 -Â Return a value of the cell at the intersection of a particular row and column**

=INDEX($C$4:$G$7, MATCH($B11, $B$4:$B$7, 0), MATCH(C$10, $C$3:$G$3, 0))<C11

returnsÂ 27,3. The picture above shows how the formula finds the value at the intersection of a given row and column number.

**Step 4 -Â Compare returned value to current value**

=INDEX($C$4:$G$7, MATCH($B11, $B$4:$B$7, 0), MATCH(C$10, $C$3:$G$3, 0))<C11

becomes

27,3>C11

becomes

27,3>27,3

returns FALSE. Cell C11 is **not **highlighted green.

## 2. Compare two columns and highlight differences

This section demonstrates a conditional formatting formula that will highlight the differences between two columns. The image above shows two cell ranges containing values, the first one is in column B and the second one is in column D.

Values "BB", "GG", and "GG" are highlighted, they only exist in column B. Values "DD" and "FF" are highlighted, they only exist in column D.

Conditional formatting is a built-in feature that allows you to format specific cells based on a condition or criteria.

The conditional formatting formula presented in this article highlights values that only exist in one column, in other words, they differ from the values in the other column. You can pick any format or fill color and the formula lets you build advanced criteria that must be met.

### 2.1 How to highlight values

- Select cell range B3:B7.
- Go to tab "Home" on the ribbon if you are not there already.
- Press with mouse on the Conditional Formatting button.
- Press with mouse on "New Rule...".

- Press with mouse on "Use a formula to determine which cells to format".
- Type: =AND($D$3:$D$7<>B3)
- Press with mouse on "Format..." button.
- Press with mouse on "Fill" tab.
- Pick a color.
- Press with left mouse button on OK.
- Press with left mouse button on OK.

Repeat above steps with column D, the formula isÂ =AND($B$3:$B$7<>D3)

### 2.2 Explaining conditional formatting formula

#### Step 1 - Check if cell range D3:D7 is not equal to cell B3

Reference $D$3:$D$7 is an absolute cell reference meaning it is locked, it won't change when the CF moves to the next cell.

The less than and larger than sign combined means not equal to.

$D$3:$D$7<>B3

becomes

$D$3:$D$7<>B3

and returns {TRUE; TRUE; TRUE; TRUE; TRUE}.

#### Step 2 - Check if all boolean values are TRUE

AND($D$3:$D$7<>B3)

AND($D$3:$D$7<>B3)

becomes

AND({TRUE; TRUE; TRUE; TRUE; TRUE})

and returns TRUE. Cell B3 is highlighted.

## 3. Compare two columns and highlight values in common

A conditional formatting formula highlights values in column B that also exist in column D.

The same thing happens in column D, a conditional formatting formula highlights values in common between column B and D.

### How to highlight common values

- Select cell range B3:B7
- Go to tab "Home" on the ribbon if you are not there already
- Press with mouse on Conditional Formatting button
- Press with mouse on "New Rule..."

- Press with mouse on "Use a formula to determine which cells to format"
- Type: = COUNTIF($D$3:$D$7, B3)

- Press with mouse on "Format..." button
- Press with mouse on "Fill" tab.
- Pick a color
- Press with left mouse button on OK
- Press with left mouse button on OK

Repeat above steps with column D, the formula is at the top of this article.

### Explaining conditional formatting formula

The COUNTIF function counts how many times value in cell B3 is found in cell rangeÂ $D$3:$D$7. B3 changes to B4 when Excel moves on to next cell below, however, that is not the case withÂ $D$3:$D$7.

The $ dollar signs make this cell reference locked, in other words, it doesn't change.

The Conditional Formatting in Excel interprets all numbers except 0 as TRUE so if the COUNTIF function finds a value twice and returns 2 doesn't matter, it still highlights the cell.

## 4. Compare two lists of data and highlight common records

In this blog post I will demonstrate a conditional formatting formula that will highlight common records in two lists. The image above shows you highlighted records in List 1 that also exists in sheet2.

You can also use a formula to extract shared records or an Excel defined table, if you prefer that. There is also an article written forÂ Comparing two columns and highlight values in common.

There are more links to related articles in the sidebar.

### Create named ranges

When constructing a conditional formatting formula you can only reference cells on current sheet. But there is a workaround.Â The answer isÂ named ranges.

Here is how to create named ranges for this example:

- Go to sheet List 2
- Select cell range A2:A13
- Press with left mouse button on in Name box
- Type a name (Year)
- Repeat step 1 to 4 with remaining columns.

### Setup COUNTIFS function

The COUNTIFS function looks for duplicate records in the second list (List 2).

**COUNTIFS(**criteria_range1,criteria1, criteria_range2,Â criteria2...**)**

Counts the number of cells specified by a given set of conditions or criteria

In this example:

List 1:Column A - List 2: Column A (Year)

List 1:Column B - List 2: Column B (Asset)

List 1:Column C - List 2: Column C (Cost)

COUNTIFS(YEAR, $A2, ASSET, $B2, COST, $C2)

This formula contains absolute and relative cell references. The conditional formatting formula must look for values in matching columns.

$A2 is a cell reference to values in column A. The column ($A) is absolute but the row (2) is relative. When the conditional formatting formula runs the next row, only the row number changes, example $A3. The named ranges do not change.

If the COUNTIFS function finds one matching record it returns 1, if nothing is found 0 (zero) is returned. 0 (zero) is the equivalent to FALSE so the Conditional formattingÂ will not highlight a cell i FALSE is returned.

### Highlight common records from two lists Excel 2007

How to apply conditional formatting formula:

- Select cells A2:C11 (Sheet: List 1)
- Press with left mouse button on "Home" tab
- Press with left mouse button on "Conditional Formatting" button
- Press with left mouse button on "New Rule.."
- Press with left mouse button on "Use a formula to determine which cells to format"
- Type =COUNTIFS(YEAR, $A2, ASSET, $B2, COST, $C2)Â in "Format values where this formula is TRUE" window.

(The formula shown in the image above is not used in this article) - Press with left mouse button on "Format.." button
- Press with left mouse button on "Fill" tab
- Select a color for highlighting cells.
- Press with left mouse button on "Ok"
- Press with left mouse button on "Ok"
- Press with left mouse button on "Ok"

## 5. Compare two tables and highlight differences

The image above demonstrates a conditional formatting formula that highlights records that only exist in one table. There are two tables in this example: List 1 and List 2.

If you are looking for a conditional formatting formula that highlights records shared by both tables:Â Compare tables: Highlight common records. There is also an article that demonstrates how to filter records not in both tables.

The conditional formatting formula does not work with cell references outside the current sheet so we need to rely on named ranges for this to work.

### Create named ranges

- Select A2:A13 on sheet "List 2"
- Type Year in Name Box
- Press Enter

Repeat with remaining ranges:

Sheet: List 2 , Range:B2:B13, Name: Asset

Sheet: List 2 , Range:C2:C13, Name: Cost

Sheet: List 1 , Range:A2:A11, Name: Year1

Sheet: List 1 , Range:B2:B11, Name: Asset1

Sheet: List 1 , Range:C2:C11, Name: Cost1

### Highlight records existing in only one list

How to apply conditional formatting formula:

Sheet: List 1

- Select cells A2:C11 (Sheet: List 1)
- Press with left mouse button on "Home" tab
- Press with left mouse button on "Conditional Formatting" button
- Press with left mouse button on "New Rule.."
- Press with left mouse button on "Use a formula to determine which cells to format"
- Type =COUNTIFS(Year, $A2, Asset, $B2, Cost, $C2)=0Â in "Format values where this formula is TRUE" window.

(The formula displayed in the image above is not used in this article) - Press with left mouse button on "Format.." button
- Press with left mouse button on "Fill" tab
- Select a color for highlighting cells.
- Press with left mouse button on "Ok"
- Press with left mouse button on "Ok"
- Press with left mouse button on "Ok"

Sheet: List 2

- Select cells A2:C13 (Sheet: List 2)
- Press with left mouse button on "Home" tab
- Press with left mouse button on "Conditional Formatting" button
- Press with left mouse button on "New Rule.."
- Press with left mouse button on "Use a formula to determine which cells to format"
- Type =COUNTIFS(Year1, $A2, Asset1, $B2, Cost1, $C2)=0Â in "Format values where this formula is TRUE" window.

(The formula displayed in the image above is not used in this article) - Press with left mouse button on "Format.." button
- Press with left mouse button on "Fill" tab
- Select a color for highlighting cells.
- Press with left mouse button on "Ok"
- Press with left mouse button on "Ok"
- Press with left mouse button on "Ok"

### Highlight records existing in only one list, excel 2003

The COUNTIFS function was introduced in Excel 2007 and if you have an earlier version you need another formula shown below. The COUNTIF functions returns arrays that are multiplied, the SUMPRODUCT function then adds the numbers and returns a total.

I want to compare price of a material for previous month and current month and if the difference exceeds a certain limit want to highlight the same.

Hai

What a surprise..!

I have visited so many websites, youtube channels for my problem.

I have a excel data that is 2 columns,

column 1 is 2,72,132 records

column 2 is 519 records

I have to highlight or select the records that 519 records which are column no.1

But No body have given correct suggesion.

All are given =Match() or =vlookup() formulas.

but not succeded.

At last your help has given correct result

Thank you for great help which is simple but valuable formula i.e., = COUNTIF($D$3:$D$7, B3).

Thanks once again

.. RAVINDER.
