How to compare 2 tables in Excel. Comparing data in Excel on different sheets

Perhaps everyone who works with data in Excel is faced with the question of how to compare two columns in Excel for coincidences and differences. There are several ways to do this. Let's take a closer look at each of them.

How to compare two columns in Excel row by row

When comparing two columns with data, it is often necessary to compare the data in each separate row for coincidences or differences. We can do this analysis using the function. Let's see how it works in the examples below.

Example 1. How to compare two columns for matches and differences in one row

In order to compare the data in each row of two columns in Excel, we will write a simple formula. The formula should be inserted in each row in the adjacent column, next to the table that contains the basic data. Having created the formula for the first row of the table, we can stretch / copy it to the rest of the rows.

In order to check whether two columns of the same row contain the same data, we need the formula:

\u003d IF (A2 \u003d B2, “Match”, “”)

The formula that determines the differences between the data of two columns in one row will look like this:

\u003d IF (A2<>B2; "Do not match"; "")

We can fit the check for matches and differences between two columns in one row in one formula:

\u003d IF (A2 \u003d B2, “Match”, “Don't match”)

\u003d IF (A2<>B2; "Do not match"; "Match")

An example of a calculation result might look like this:

In order to compare data in two columns of the same row case sensitively, use the formula:

\u003d IF (MATCH (A2, B2), “Match”, “Unique”)

How to compare multiple columns for matches in one row Excel

Excel has the ability to compare data in multiple columns of one row according to the following criteria:

  • Find rows with the same values \u200b\u200bin all columns of the table;
  • Find rows with the same values \u200b\u200bin any two columns of the table;

Example 1. How to find matches in one row in multiple columns of a table

Let's imagine that our table consists of several columns of data. Our task is to find rows in which the values \u200b\u200bare the same in all columns. The functions Excel and. The formula for determining matches will be as follows:

\u003d IF (AND (A2 \u003d B2; A2 \u003d C2); “Match”; ”“)

If our table has a lot of columns, then it will be easier to use the function in combination with:

\u003d IF (COUNTIF ($ A2: $ C2, $ A2) \u003d 3; ”Matches”; ”“)

In the formula, “5” is the number of columns in the table for which we created the formula. If your table has more or less columns, then this value should be equal to the number of columns.

Example 2. How to find matches in one row in any two columns of a table

Imagine that our task is to identify from a table with data in several columns those rows in which the data coincides or is repeated in at least two columns. The functions and will help us with this. Let's write a formula for a table consisting of three columns of data:

\u003d IF (OR (A2 \u003d B2; B2 \u003d C2; A2 \u003d C2); ”Match”; ”“)

In cases where there are too many columns in our table, our formula with the function will be very large, since in its parameters we need to specify the criteria for matching between each column of the table. An easier way, in this case, is to use a function.

\u003d IF (COUNTIF (B2: D2; A2) + COUNTIF (C2: D2; B2) + (C2 \u003d D2) \u003d 0; "Unique string"; "Not unique string")

\u003d IF (COUNTIF ($ B: $ B; $ A5) \u003d 0; “No matches in column B”; “There are matches in column B”)

This formula checks the values \u200b\u200bin column B to see if they match the data in the cells in column A.

If your table consists of a fixed number of rows, you can specify a clear range in the formula (for example, $ B2: $ B10 ). This will speed up the formula.

How to compare two columns in Excel for matches and highlight with color

When we search for matches between two columns in Excel, we may need to visualize the matches or differences found in the data, for example, using color highlighting. The easiest way to highlight coincidences and differences with color is to use “Conditional Formatting” in Excel. Let's see how to do this in the examples below.

Find and highlight matches in multiple columns in Excel

In cases where we need to find matches in several columns, then for this we need:

  • Select columns with data in which you want to calculate matches;
  • On the "Home" tab on the Toolbar, click on the menu item "Conditional Formatting" -\u003e "Cell Selection Rules" -\u003e "Duplicate Values";
  • In the pop-up dialog box, select the item “Duplicate” in the left drop-down list, in the right drop-down list, select the color of the duplicate values. Click the "OK" button:
  • After that, in the selected column, the matching color will be highlighted:

Find and highlight matching rows in Excel

Finding matching cells with data in two or more columns and finding matches for entire rows with data are different concepts. Note the two tables below:

The tables above contain the same data. Their difference is that in the example on the left we were looking for matching cells, and on the right we found whole repeating lines of data.

Let's see how to find matching rows in a table:

  • To the right of the table with data, create an auxiliary column, in which, opposite each row with data, we put a formula that combines all the values \u200b\u200bof the table row into one cell:

\u003d A2 & B2 & C2 & D2

In the auxiliary column, you will see the combined table data:

Now, to determine the matching rows in the table, follow these steps:

  • Select an area with data in the auxiliary column (in our example, this is a range of cells E2: E15 );
  • On the "Home" tab on the Toolbar, click on the menu item "Conditional Formatting" -\u003e "Cell Selection Rules" -\u003e "Duplicate Values";
  • In the pop-up dialog box, select “Duplicate” in the left drop-down list, in the right drop-down list, select what color the duplicate values \u200b\u200bwill be highlighted. Click the "OK" button:
  • After that, duplicate lines will be highlighted in the selected column:

After installing the add-in, you will have a new tab with a command to call the function. When you click on the command Comparing ranges a dialog box for entering parameters appears.

This macro allows you to compare tables of any size and with any number of columns. Comparison of tables can be done one, two or three columns at a time.

The dialog box is divided into two parts: left for the first table and right for the second.

To compare tables, follow these steps:

  • Specify table ranges.
  • Set a checkbox (checkbox / checkbox) under the selected range of tables if the table includes a header (header row).
  • Select the columns of the left and right tables by which the comparison will be carried out (if the ranges of tables do not include headers, the columns will be numbered).
  • Specify the type of comparison.
  • Select the option for displaying results.

Table comparison type

The program allows you to select several types of table comparison:

Find rows in one table that are missing in another table

When this type of comparison is selected, the program searches for rows from one table that are absent in another. If you compare tables on several columns, then the result of the work will be rows in which there is a difference in at least one of the columns.

Find matching lines

When choosing this type of comparison, the program finds rows that match in the first and second tables. Rows are considered matched if the values \u200b\u200bin the selected comparison columns (1, 2, 3) of one table completely coincide with the values \u200b\u200bof the columns of the second table.

An example of the program's work in this mode is shown on the right in the picture.

Match tables based on selected

In this comparison mode, opposite each row of the first table (selected as the main one), the data of the matching row of the second table is copied. If there are no matching rows, the row opposite the main table remains empty.

Comparing tables on four or more columns

If you lack the functionality of the program and need to match tables in four or more columns, then you can get out of the situation as follows:

  • Create in tables by empty column.
  • On new columns using the formula \u003d COUPLING merge the columns you want to compare.

This way you will end up with 1 column containing the values \u200b\u200bof multiple columns. Well, you already know how to match one column.

When working with large amounts of information, the user may be faced with such a task as comparing two tabular data sources. When storing data in a single accounting system (for example, systems based on 1C Enterprise, systems using SQL databases), the capabilities built into the system or DBMS can be used to compare data. As a rule, for this it is enough to involve a programmer who will write a query to the database, or a software report mechanism. An experienced user who has the skill of writing 1C or SQL queries can also handle a query.

Problems begin when you need to perform a data comparison task urgently, and the involvement of a programmer and his writing a request or program report on time may exceed the deadlines set for solving the task. Another equally common problem is the need to compare information from different sources. In this case, setting a problem for a programmer will sound like an integration of two systems. Solving such a problem will require a higher qualification of the programmer and will also take more time than development in a single system.

To solve the indicated problems, the ideal technique is to use the Microsoft Excel spreadsheet editor for data comparison. Most of the common management and regulatory accounting systems support export to Excel format. This task will only require a certain user qualification to work with this office suite and will not require programming skills.

Let's consider the solution to the problem of comparing tables in Excel using an example. We have two tables containing lists of apartments. Sources of unloading - 1C Enterprise (construction accounting) and a table in Excel (sales accounting). Tables are located in the Excel workbook on the first and second sheets, respectively.

Our task is to compare these lists by address. The first table contains all the apartments in the house. The second table contains only apartments sold and the name of the buyer. The ultimate goal is to display the buyer's name in the first table for each apartment (for those apartments that have been sold). The task is complicated by the fact that the address of the apartment in each table is constructional and consists of several fields: 1) the address of the building (house), 2) the section (entrance), 3) the floor, 4) the number on the floor (for example, from 1 to 4) ...

To compare two Excel tables, we need to ensure that each row in both tables is identified by one field, not four. You can get such a field by combining the values \u200b\u200bof the four address fields with the Concatenate () function. The purpose of the Concatenate () function is to combine several text values \u200b\u200binto one line. The values \u200b\u200bin the function are listed through the ";" symbol. The values \u200b\u200bcan be either cell addresses or arbitrary text specified in quotes.

Step 1. Insert an empty column "A" at the beginning of the first table and write the formula in the cell of this column opposite the first line with the data:
\u003d CONNECT (B3; "-"; C3; "-"; D3; "-"; E3)
For the convenience of visual perception, we have set "-" symbols between the values \u200b\u200bof the merged cells.

Step 2. Copy the formula into the following cells in column A.

Step 4. To compare Excel tables by values, use the VLOOKUP () function. The purpose of the VLOOKUP () function is to search for a value in the leftmost column of the table and return the value of a cell located in the specified column of the same row. The first parameter is the desired value. The second parameter is the table in which the value will be searched. The third parameter is the number of the column from which the value will be returned in the found row. The fourth parameter is the type of search: false is an exact match, true is an approximate match. Since the output information should be placed in the first table (it was in it that the names of the buyers were required to be added), then the formula will be written in it. Let's form a formula in the free column to the right of the table opposite the first data row:
\u003d VLOOKUP (A3; Sheet2! $ A $ 3: $ F $ 10; 6; FALSE)
When copying formulas, Smart Excel automatically changes the cell addressing. In our case, the desired value for each row will change: A3, A4, etc., and the address of the table in which the search is being conducted must remain unchanged. To do this, fix the cells in the table address parameter with "$" symbols. Instead of "Sheet2! A3: F10" we make "Sheet2! $ A $ 3: $ F $ 10".

Good day!

This article is dedicated to solving such a question as how to compare two tables in Excel, well, or at least two columns. Yes, working with tables is convenient and good, but when you need to compare them, it is quite difficult to do it visually. Perhaps a table of up to ten or two, you can sort it visually, but when they exceed thousands, then you will need additional analysis tools.

Alas, there is no magic wand with which everything will be done in one click and the information will be verified, it is necessary to prepare the data, and write formulas, and other procedures that allow you to compare your tables.

Let's consider several options and possibilities for comparing tables in Excel:

The easy way,

This is the simplest and most basic way to compare two tables. It is possible to compare in this way both numeric values \u200b\u200band text values. For example, let's compare two ranges of numerical values, just writing in a neighboring cell the formula for their equality \u003d C2 \u003d E2, as a result, if the cells are equal, we get the answer "TRUE", And if there are no matches, there will be "FALSE"... Now, by simple auto copying, we copy it onto our formula that allows us to compare two columns in Excel and see the difference.

Quickly highlight values \u200b\u200bthat differ

This is also not a very cumbersome way. If you just need to find and make sure that there are, well, or no differences between the tables, you need to select the "Find and Select" menu button on the "Home" tab, after selecting the range where you want to compare two tables in Excel. In the menu that opens, select the item "Select a group of cells ..." and in the dialog that appears, select Line differences.

Compare two tables in Excel using conditional formatting

This is a very good way, in which you can see the highlighted values, which differ when comparing two tables. You can apply on the tab "Home"by pressing the button "Conditional Formatting" and in the provided list select "Rule Management".
In the dialog box Conditional Formatting Rules Manager, press the button "Create rule" and in a new dialog "Creating a Formatting Rule", choose a rule. In field Change Rule Description we enter the formula \u003d $ C2<>$ E2 to define the cell to be formatted and press the button "Format".
We define the style of how our value will be formatted, which meets the criterion.
Now our newly created rule has appeared in the list of rules, you select it, click "OK".

And the whole rule applied to our range, where we are trying to check for similarity between two tables, and the differences became visible, to which the conditional formatting was applied.

How to compare two tables in Excel using the COUNTIF function and rules

All of the above methods are good for ordered tables, but when the data is not ordered, other methods are needed, one of which we will now consider. Imagine, for example, we have 2 tables, the values \u200b\u200bin which are slightly different and we need to compare these tables to determine the value that is different. Select the value in the range of the first table and on the tab "Home", menu item "Conditional Formatting" and in the list, click item "Create a rule ...", choose the rule "Use a formula to define formatted cells", we enter the formula \u003d ($ C $ 1: $ C $ 7; C1) \u003d 0 and select the conditional formatting format.

The formula checks the value from a specific cell C1 and compares it to the specified range $ C $ 1: $ C $ 7 from the second column. We copy the rule for the entire range, in which we compare the tables and get the values \u200b\u200bhighlighted in the cells, which are not repeated.

How to compare two tables in Excel using the VLOOKUP function

In this variant we will use which will allow us compare two tables for matches. To compare two bars, enter the formula \u003d VLOOKUP (C2; $ D $ 2: $ D $ 7; 1; 0) and copy it over the entire range to be compared. This formula sequentially begins to check whether there are duplicates of the value from column A in column B, and, accordingly, returns the value of the element if it was found there, if the value is not found, we get.

How to compare two tables in Excel functions IF

This option provides for the use of a logical one, and the difference of this method is that not all of it will be used to compare two columns, but only that part of it that is needed for comparison.

For example, let's compare two columns A and B on the worksheet, in the next column C we enter the formula: \u003d IF ((MATCH (C2, $ E $ 2: $ E $ 7; 0)); ""; C2) and copy it all over. This formula allows you to view sequentially whether certain items from the specified column A are in column B and returns a value if it was found in column B.

Compare two tables using VBA macro

There are many ways to check if two tables are similar. , but some options are only possible with VBA macros. Macros for comparing two tables , unifies this process and significantly reduces the time spent on data preparation. Based on the task you are solving and knowledge of VBA macros, you can create any variant of macros. Below I have given the methodology indicated on the official Microsoft page. You need to create a module for VBA code and enter the code:

Sub Find_Matches () Dim CompareRange As Variant, x As Variant, y As Variant "Set CompareRange equal to the compared range Set CompareRange \u003d Range (" B1: B11 ")" If the compared range is on another sheet or workbook, "use the following syntax" Set CompareRange \u003d Workbooks ("Book2"). _ "Worksheets (" Sheet2 "). Range (" B1: B11 ")" "Compare each item in the selection to each item" CompareRange For Each x In Selection For Each y In CompareRange If x \u003d y Then x.Offset ( 0, 2) \u003d x Next y Next x End Sub

Sub Find_Matches ()

Dim CompareRange As Variant, x As Variant, y As Variant

"Setting the CompareRange variable equal to the compared range

Set CompareRange \u003d Range ("B1: B11")

"If the compared range is on another list or book,

"use the following syntax

"Set CompareRange \u003d Workbooks (" Book2 "). _

Hot shortcut keys Alt + F8... In the new dialog box, select your macro Find_similar and execute it.

Comparison using the Inquire add-on

This comparison option became available with the release of 2013 version of Excel, the editor was added inquire add-onwhich will analyze and compare two Excel files. This method is good when you need to compare two files, in the case when your colleague was working on a book and made some changes. To determine these changes, you need a tool WorkbookCompare in add-inInquire.

Well, we looked at 8 ways to compare two tables in Excel, these options will help you solve your analytical tasks and simplify your work.
