Filter in excel with formula

The FILTER function allows you to filter a range of data based on criteria you define.

In the following example we used the formula =FILTER(A5:D20,C5:C20=H2,»») to return all records for Apple, as selected in cell H2, and if there are no apples, return an empty string («»).

The FILTER function filters an array based on a Boolean (True/False) array.

=FILTER(array,include,[if_empty])

Argument	Description
array Required	The array, or range to filter
include Required	A Boolean array whose height or width is the same as the array
[if_empty] Optional	The value to return if all values in the included array are empty (filter returns nothing)

Notes: 

• An array can be thought of as a row of values, a column of values, or a combination of rows and columns of values. In the example above, the source array for our FILTER formula is range A5:D20.

• The FILTER function will return an array, which will spill if it’s the final result of a formula. This means that Excel will dynamically create the appropriate sized array range when you press ENTER. If your supporting data is in an Excel table, then the array will automatically resize as you add or remove data from your array range if you’re using structured references. For more details, see this article on spilled array behavior.

• If your dataset has the potential of returning an empty value, then use the 3rd argument ([if_empty]). Otherwise, a #CALC! error will result, as Excel does not currently support empty arrays.

• If any value of the include argument is an error (#N/A, #VALUE, etc.) or cannot be converted to a Boolean, the FILTER function will return an error.  

• Excel has limited support for dynamic arrays between workbooks, and this scenario is only supported when both workbooks are open. If you close the source workbook, any linked dynamic array formulas will return a #REF! error when they are refreshed.

Examples

FILTER used to return multiple criteria

In this case, we’re using the multiplication operator (*) to return all values in our array range (A5:D20) that have Apples AND are in the East region: =FILTER(A5:D20,(C5:C20=H1)*(A5:A20=H2),»»).

FILTER used to return multiple criteria and sort

In this case, we’re using the previous FILTER function with the SORT function to return all values in our array range (A5:D20) that have Apples AND are in the East region, and then sort Units in descending order: =SORT(FILTER(A5:D20,(C5:C20=H1)*(A5:A20=H2),»»),4,-1)

In this case, we’re using the FILTER function with the addition operator (+) to return all values in our array range (A5:D20) that have Apples OR are in the East region, and then sort Units in descending order: =SORT(FILTER(A5:D20,(C5:C20=H1)+(A5:A20=H2),»»),4,-1).

Notice that none of the functions require absolute references, since they only exist in one cell, and spill their results to neighboring cells.

Dynamic arrays and spilled array behavior

Implicit intersection operator: @

The FILTER function «filters» a range of data based on supplied criteria. The result is an array of matching values from the original range. In plain language, the FILTER function will extract matching records from a set of data by applying one or more logical tests. Logical tests are supplied as the include argument and can include many kinds of formula criteria. For example, FILTER can match data in a certain year or month, data that contains specific text, or values greater than a certain threshold.

The FILTER function takes three arguments: array, include, and if_empty. Array is the range or array to filter. The include argument should consist of one or more logical tests. These tests should return TRUE or FALSE based on the evaluation of values from array. The last argument, if_empty, is the result to return when FILTER finds no matching values. Typically this is a message like «No records found», but other values can be returned as well. Supply an empty string («») to display nothing.

The results from FILTER are dynamic. When values in the source data change, or the source data array is resized, the results from FILTER will update automatically. Results from FILTER will «spill» onto the worksheet into multiple cells.

Basic example

To extract values in A1:A10 that are greater than 100:

=FILTER(A1:A10,A1:A10>100)

To extract rows in A1:C5 where the value in A1:A5 is greater than 100:

=FILTER(A1:C5,A1:A5>100)

Notice the only difference in the above formulas is that the second formula provides a multi-column range for array. The logical test used for the include argument is the same.

Note: FILTER will return a #CALC! error if no matching data is found

Filter for Red group

In the example shown above, the formula in F5 is:

=FILTER(B5:D14,D5:D14=H2,"No results")

Since the value in H2 is «red», the FILTER function extracts data from array where the Group column contains «red». All matching records are returned to the worksheet starting from cell F5, where the formula exists.

Values can be hardcoded as well. The formula below has the same result as above with «red» hardcoded into the criteria:

=FILTER(B5:D14,D5:D14="red","No results")

No matching data

The value for is_empty is returned when FILTER does not find matching results. If a value for if_empty is not provided, FILTER will return a #CALC! error if no matching data is found:

=FILTER(range,logic) // #CALC! error

Often, is_empty is configured to provide a text message to the user:

=FILTER(range,logic,"No results") // display message

To display nothing when no matching data is found, supply an empty string («») for if_empty:

=FILTER(range,logic,"") // display nothing

Values that contain text

To extract data based on a logical test for values that contain specific text, you can use a formula like this:

=FILTER(rng1,ISNUMBER(SEARCH("txt",rng2)))

In this formula, the SEARCH function is used to look for «txt» in rng2, which would typically be a column in rng1. The ISNUMBER function is used to convert the result from SEARCH into TRUE or FALSE. Read a full explanation here.

Filter by date

FILTER can be used with dates by constructing logical tests appropriate for Excel dates. For example, to extract records from rng1 where the date in rng2 is in July you can use a generic formula like this:

=FILTER(rng1,MONTH(rng2)=7,"No data") 

This formula relies on the MONTH function to compare the month of dates in rng2 to 7.  See full explanation here.

Multiple criteria

At first glance, it’s not obvious how to apply multiple criteria with the FILTER function. Unlike older functions like COUNTIFS and SUMIFS, which provide multiple arguments for entering multiple conditions, the FILTER function only provides a single argument, include, to target data. The trick is to create logical expressions that use Boolean algebra to target the data of interest and supply these expressions as the include argument. For example, to extract only data where one value is «A» and another is greater than 80, you can use a formula like this:

=FILTER(range,(range="A")*(range>80),"No data")

The math operation of addition (*) joins the two conditions with AND logic: both conditions must be TRUE in order for FILTER to retrieve the data. See a detailed explanation here.

Complex criteria

To filter and extract data based on multiple complex criteria, you can use the FILTER function with a chain of expressions that use boolean logic. For example, the generic formula below filters based on three separate conditions: account begins with «x» AND region is «east», and month is NOT April.

=FILTER(data,(LEFT(account)="x")*(region="east")*NOT(MONTH(date)=4))

See this page for a full explanation. Building criteria with logical expressions is an elegant and flexible approach that can be extended to handle many complex scenarios. See below for more examples.

Notes

1. FILTER can work with both vertical and horizontal arrays.
2. The include argument must have dimensions compatible with the array argument, otherwise FILTER will return #VALUE!
3. If the include array includes any errors, FILTER will return an error.

This post will guide you how to extracts matched values using FILTER function in Microsoft Excel 365. And also will introduce that how to use FILTER function with same examples in Excel 365.

The FILTER function “filters” a set of data according to the conditions specified. The outcome is an array of values that match those in the original range. Simply said, the FILTER function extracts matched records from a collection of data using one or more logical checks. The include argument specifies logical tests, which might encompass a wide variety of formula conditions. For instance, FILTER may match data from a given year or month, data containing specific content, or numbers above a specified threshold.

=FILTER(array,include,[if empty])

Three parameters are required for the FILTER function: array, include, and if empty.

Where:

• Array – This is required argument. The range or array to filter is specified by array.
• Include – This is required argument. Include one or more logical tests in the include These tests should return TRUE or FALSE depending on the array values evaluated.
• If_empty – This is option argument. The last input, if empty, specifies the value to return if FILTER does not discover any matching values. Typically, this is a message along the lines of “No records found,” although other values may also be returned. To show nothing, provide an empty string (“”).

Entering FILTER Formula in Excel

---

FILTER provides dynamic results. When the values in the source data change or the size of the source data array changes, the FILTER results are updated automatically. The results of FILTER will “leak” into numerous cells on the worksheet.

To filter data in Excel using the FILTER function, follow these steps:

Step1: To begin your filter formula, enter =FILTER(.

Step2: Enter the address for the range of cells containing the data you want to filter, for example, A2:C10.

Step3: Type a comma, followed by the filter's condition, such as B2:B20>3 (To specify a condition, type the address of the “criteria column,” such as C1:C, followed by an operator symbol such as greater than (>), and finally the criterion, such as the number 3.

Step4: Complete the parenthesis with a closing parenthesis and then hit enter on the keyboard. Your full formula will appear as follows: =FILTER(A2:C10, B2:B20>3)

I’ll begin with the fundamentals of utilizing the FILTER function, and then demonstrate some more advanced uses of the FILTER function. This article discusses the FILTER function as a formula entered into spreadsheet cells, not the filter command accessible from the toolbar and pop-up menus.

While using the FILTER function in Excel is almost identical to using it in Google Sheets, there are some subtle variations.

Excel filtering by a single criteria

---

To begin, let’s review how to use Excel’s FILTER function in its simplest version, with a single condition/criteria.

I’ll demonstrate how to filter data using a number, a cell value, a text string, or a date… and I’ll also demonstrate how to utilize a variety of “operators” in the filter condition (Less than, Equal to, etc…).

Example 1: How to use a number as a filter

---

In this first demonstration of how to use the filter tool in Excel, we have a list of students and their grades and wish to create a filtered list of only students with flawless grades.

The assignment: Display a list of students and their grades, but only those who have earned an A.

The reasoning: Filter the range A2:B10 for values larger than 0.7 in the column B2:B10 (70 percent ). Then you can use the following FILTER formula,type:

=FILTER(A2:B10, B2:B10 >0.7)

Example 2: How to filter in Excel by a cell value

---

In this excel filter function example, we want to do the same thing as stated before, but rather than inputting the condition straight into the formula, we’re going to use a cell reference.

When you filter in Excel by a cell value, your sheet is configured in such a way that you may alter the value in the cell at any moment, which updates the value to which the filter criterion is tied.

In this example, rather than explicitly entering the value “0.8” into the formula, the filter criterion is set to cell G1, which contains the “0.8” value.

The assignment: Display a list of students and their grades, but only those with a score of less than 80%.

The reasoning: Filter the range A2:B10 to the extent that B2:B10 is smaller than the value supplied in column G1 (0.8).

You can use the following FILTER formula, type:

=FILTER(A2:B10, B2:B10 <G1)

Example 3: Using Excel’s text filter

---

In this example, we’ll utilize a text string as the filter formula’s criterion. This is fairly similar to using a number, except that the text to filter must be enclosed in quote marks.

We are filtering a list of customers and their payment status in this instance, and we want to present just customers with a payment status of “Payed“.

The objective is to provide a list of clients that have paid on their payments.

The reasoning: Filter the range A2:B6 by substituting the string “ Payed ” for B2:B6.

The following formula: In this example, the formula below is typed in the cell (E1).

=FILTER(A3:B12, B2:B6=" Payed ")

Example 4: Using NOT EQUAL TO as a FILTER condition in Excel

---

Now that you have a working knowledge of how to use the filter function in Excel, here is another example of filtering by a string of text, but this time we will use the “not equal” operator (<>) to demonstrate how to filter a range and return data that is NOT equal to the criteria you set.

Additionally, we will utilize a bigger data set in this example to show a more comprehensive usage of the FILTER function in the real world.

You may be surprised at how often a circumstance arises in which you need to filter data that is “not equal to” a certain number or piece of text.

In this example, we’ll use a report/spreadsheet to display data from sales calls that occur at your organization, and we’ll filter the data to exclude a certain sales person (Scott) from the result.

The assignment: Display sales call statistics for all sales representatives except ” Scott “.

The reasoning: Filter the range A2:C10 for values A2:A10 that DO NOT match the string “Scott “.

The following formula: In this example, the formula below is typed in the cell (E1).

=FILTER(A2:C10, A2:A10 <>"Scott")

Take note that the filtered data on the right side of the figure above does not include any of Scott ‘s rows/calls.

 Example 5: How to use the date filter in Excel

---

Filtering in Excel by a date may be accomplished in a few different methods, which I will demonstrate below. If you attempt to put a date into the FILTER function in the same way that you would typically type into a cell, the formula will fail to operate properly.

Therefore, you may either enter the date you want to filter into a cell and then reference that cell in your formula… Alternatively,  you may use the DATE function.

When filtering by date, the same operators (>, =, etc…) are available as they are in other FILTER function applications. Each individual day/date in Excel is merely a number that has been formatted differently. In Excel, for example, the date “01/30/2022” is just the serial number “44591” formatted as a date. Each time you add a day to the calendar, this number increases by one… For example, “44591” “44592” “44593”

Thus, if one date is farther in the future, it might be regarded “greater than” another. In contrast, if one date is farther in the past, it might be considered to be “less than” another.

In this example, we’ll use a cell reference to filter on a date. This is identical to the example discussed in Example 2, except that we are dealing with dates instead of percentages.

Consider the following scenario: we want to filter a list of students, their exam results, and the dates on which the tests were administered… and we wish to display only tests conducted before to June (05/01/2022).

=FILTER(A2:C10, C2:C10 <G1)

Example 6: Filtering by date in Excel

---

In this example of date filtering in Excel, we’ll use the same data as in the previous one and attempt to obtain the same results… however, instead of referencing a cell, we’ll utilize the DATE function, which allows you to put the date straight into the FILTER function.

When using the DATE function to provide a date, you must first input the year, followed by the month and finally the day… each denoted with a comma (shown below).

The assignment: Display only exams given before to May

The reasoning: Filter the range A2:C10 so that C2:C10 is less than or equal to the date (05/01/2022).

The following formula: In this example, the formula below is typed in the cell (D3).

=FILTER(A2:C10,C2:C10<DATE(2022,5,1))

Example 7: Filtering based on two Conditions

---

When utilizing the Excel FILTER function, you may want to produce data that fits many criteria. I’ll demonstrate two methods for filtering by several criteria in Excel, depending on the scenario and the desired behavior of the calculation.

The conventional method of adding another condition to your filter function (as shown by the Excel formula syntax) allows you to provide a second condition, where both the first AND second conditions must be fulfilled in order for the filter output to be returned.

However, I will demonstrate how to make a little tweak to the function so that you may choose to return/display in the filter function’s output/destination a second condition where EITHER condition might be satisfied. (To utilize AND logic, separate the conditions with an asterisk, or use a plus symbol to separate the criteria.)

In this example, we’re going to filter a collection of data and show those rows that satisfy BOTH the first and second conditions.

To utilize a second condition in this manner (using AND logic), just insert it after the first condition in the formula, separated by an asterisk (*). Each condition must be included in a separate pair of parentheses.

When a filter formula is used with several conditions, the columns referenced in each condition must be distinct.

In this case, we’d want to filter a list of clients based on their payment status and region… and to display those customers who are both current members AND paid on their payment status.

The objective is to provide a list of customers who are paid on payments, but only those who are in East region.

The reasoning: Filter the range A2:C6 such that B2:B6 equals the text “Paid,” AND C2:C6 equals the text “East“.

The following formula: In this example, the formula below is typed in the blue cell (E1).

=FILTER(A2:C6,( B2:B6="Paid")*( C2:C6 ="East"))

Example 8: Filtering Based on Two Conditions using OR Logic

---

In this example, we’re going to filter a collection of data and show those rows that satisfy either the first OR the second criterion.

To utilize a second condition in this manner (using OR logic), just insert it after the first condition in the formula, separated by a plus sign. Each condition must be included in a separate pair of parentheses (shown below).

When used in this manner, the FILTER formula allows you to choose criteria from the same or separate columns.

In this case, we’re filtering the same customer data as in the previous example, but this time we’re displaying a list of customers who either are in East region OR have paid on a payment. This will generate a list of clients to whom a payment notification have paid… whether they are current members or east region who have paid on their last payment.

The objective is to provide a list of customers who are in East region, as well as customers who have paid on payments regardless of whether they are in East region.

The following formula: In this example, the formula below is typed in the cell (E1).

=FILTER(A2:C6, (B2:B6="Paid ")+(C2:C6=" East ")

Example 9: Filter Data in Excel from Another Sheet

---

You may often encounter instances in Excel when you need to filter data from another sheet, where your raw unfiltered data is on one tab and your filter formula is on another sheet.

This may be accomplished by simply referring to a certain sheet’s name when providing the filter’s ranges. Thus, while you would typically give a range such as “A1:B4,” when referring another sheet when filtering, you indicate the sheet name by preceding the range with the sheet name and an exclamation mark, as in “SheetName!A1:B4“.

However, if the sheet name contains a space, an apostrophe must be used before and after the sheet name, as in "Sheet Name!" A1:B4.

The following is an example of how to filter data in Excel from a separate sheet, where the filter formula is located on a different sheet than the source range.

Consider the following scenario: On one sheet, you have a list of customers and their payment status, and you wish to present a filtered list of  paid customer on another sheet.

The job is to filter the list of customers on the Sheet3 and to display a separate list of customer names with a pay status on another worksheet.

The reasoning: Filter the range using the Sheet3‘ command! A2:C6, where ‘ Sheet3′ is the range! B2:B6 corresponds to the phrase “Paid“.

The following formula: In this example, the formula below is typed in the cell (A3).

=FILTER(Sheet3! A2:C6, Sheet3!B2:B6="Paid")

Example 10: Providing Maximum Number of Rows of Filtered Data

---

If your FILTER formula provides a large number of rows but your worksheet is restricted in space and you are unable to erase the data below, you may limit the amount of rows returned by the FILTER function.

Let us demonstrate how it works using a simple formula that filter data that grade is less than 0.7 from filter value in Cell F1:

=FILTER(A2:C10, B2:B10<F1)

The preceding formula produces all records that it discovers, in this instance five rows. However, imagine you only have room for two. To output just the first two rows discovered, follow these steps:

Step1: Incorporate the FILTER formula into the INDEX function’s array parameter

Step2: Use a vertical array constant such as 1;2 as the row num input to INDEX. It specifies the number of rows to return (2 in our case).

Step3: Use a horizontal array constant such as 1,2 for the column num parameter. It defines the columns that should be returned (the first 2 columns in this example).

Step4: To account for any mistakes caused by the absence of data meeting your criteria, you may wrap your calculation in the IFERROR function.

The entire excel filter formula is as follows:

=IFERROR(INDEX(FILTER(A2:C10, B2:B10<F1), {1;2},{1,2}), "No Found")

Conclusion

This section discusses the FILTER function and its many uses. In general, when it comes to time management, we need this feature for a variety of reasons. I demonstrated various techniques with accompanying examples, however there might be countless further iterations based on a variety of circumstances. If you know of another way to use this function, please share it with us.

• Excel IFERROR function
  The Excel IFERROR function returns an alternate value you specify if a formula results in an error, or returns the result of the formula.The syntax of the IFERROR function is as below:= IFERROR (value, value_if_error)….
• Excel INDEX function
  The Excel INDEX function returns a value from a table based on the index (row number and column number)The INDEX function is a build-in function in Microsoft Excel and it is categorized as a Lookup and Reference Function.The syntax of the INDEX function is as below:= INDEX (array, row_num,[column_num])…

Filtering is a common everyday action for most Excel users. Whether using AutoFilter or a Table, it is a convenient way to view a subset of data quickly. Until the FILTER function in Excel was released, there was no easy way to achieve this with formulas. When Microsoft announced the changes to Excel’s calculation engine, they also introduced a host of new functions. One of those new functions is FILTER, which returns all the cells from a range that meet specific criteria.

At the time of writing, the FILTER function is only available in Excel 365, Excel 2021 and Excel Online. It will not be available in Excel 2019 or earlier versions.

Arguments of the FILTER function

Before we look at the arguments required for the FILTER function, let’s look at a basic example to appreciate what it does.

Here the FILTER function returns all the values in cells B3-B10 where the number of characters is greater than 15. Not a scenario that many of us will need, but it perfectly demonstrates the power of the new FILTER function.

FILTER has three arguments:

=FILTER(array, include, [if_empty])

• array: The range of cells, or array of values to filter.
• include: An array of TRUE/FALSE results, where only the TRUE values are retained in the filter.
• [if_empty]: The value to display if no rows are returned.

Examples of using the FILTER function

The following examples illustrate how to use the FILTER function.

Example 1 – FILTER returns an array of rows and columns

In this example, cell F3 contains a single formula, but this formula returns an array of values into the neighboring rows and columns.

The formula in cell F3 is:

=FILTER(B3:D10,C3:C10>100)

This single formula is returning 2 rows and 3 columns of data where the values in C3-C10 are higher than 100.

Example 2 – #CALC! error caused by the FILTER function

The screenshot below displays what happens when the result of the FILTER function has zero results; we get the #CALC! error.

The formula in cell F3 is:

=FILTER(B3:D10,C3:C10>200)

As no rows meet the criteria of Invoice Value being higher than 200, the FILTER cannot return a value, so the #CALC! error is displayed.

Thankfully, Microsoft has given us the if_empty argument, which displays a message if there are no rows returned.

The formula in cell F3 is:

=FILTER(B3:D10,C3:C10>200,"No Results")

In the screenshot above, No Results displays instead of the #CALC! error.

If we wanted to display a result in each column, we could include a constant array within the if_empty argument. The following shows n/a in the Invoice Value and Days Due columns.

=FILTER(B3:D10,C3:C10>200,{"No Results","n/a","n/a"})

This formula would result in the following:

Example 3 – FILTER expands automatically when linked to a table

This example shows how the FILTER function responds when linked to an Excel table.

The FILTER is set to show items where Invoice Value is higher than 100. New records added to the Table which meet the criteria are automatically added to the spill range of the function. Amazing stuff!

Example 4 – Using FILTER with multiple criteria.

Example 4 shows how to apply FILTER with multiple criteria.

The formula in cell F3 is:

=FILTER(B3:D10,(C3:C10>50)*(D3:D10>30))

For anybody who has used the SUMPRODUCT function, this method of applying multiple conditions will be familiar. Multiplication creates AND logic (i.e., all the criteria must be TRUE). The example above shows where the Invoice Value is greater than 50 and the Days Due is greater than 30.

Addition creates OR logic (i.e., any individual condition can be TRUE).

The formula in cell G3 is:

=FILTER(B3:D10,(C3:C10>50)+(D3:D10>30))

The example above shows where the Invoice Value is greater than 50 or the Days Due is greater than 30.

Example 5 – Using FILTER for dependent dynamic drop-down lists

Drop-down lists are a data validation technique. Dependent drop-down lists are an advanced technique where the lists change depending on the result of another cell. For example, if the first drop-down list displays country names, the second drop-down list should only display cities that exist in that country. In Excel 2019 and before there are only tedious methods to achieve this effect, but the new FILTER function makes this super easy.

The formula in cell H3 is:

=UNIQUE(B3:B10)

The UNIQUE function creates a unique list to populate the drop-down in cell F4.

The formula in cell I3 is:

=FILTER(C3:C10,B3:B10=F4)

Depending on the value in cell F4, the values returned by the FILTER function change. The second drop-down in cell F6 changes dynamically based on the value in Cell F4.

Example 6 – Using FILTER with other functions

In this final example, FILTER is nested inside the SORT function.

The formula in cell F3 is:

=SORT(FILTER(B3:D10,D3:D10<=30))

First, the FILTER function returns the cells based on the Days Due being less than or equal to 30. The SORT function then puts the Customers into ascending alphabetical order.

Example 7 – Using FILTER to show matching items from a list

How can we match a list of items that could have an unknown size? We can’t keep updating our FILTER function by adding and removing criteria. And, if we had a lot of items to match, it would soon become unmanageable. So, let’s see how we can solve this.

In the example below, the formula in cell H3 returns only the customers listed in F3:F4.

The formula in cell H3 is:

=FILTER(B3:D10,COUNTIFS(F3:F4,B3:B10),"No results")

The COUNTIFS function returns a positive number if the item exists in both the data and the list, or zero if it exists in only one. Since positive numbers are always TRUE and zeros are always FALSE, this provides the TRUE/FALSE logic required for the FILTER function to return only the matching items.

NOTE: If the list starting in F3 were generated by another array formula, or by Power Query this solution would be completely dynamic (that is outside the scope of the current post, so we have used static ranges for this example).

Example 8 – Simulating wildcard search with FILTER

The FILTER function does not allow wildcard characters in the criteria. However, by using a combination of SEARCH and ISNUMBER we can simulate a similar effect.

In the example below, the formula in cell H3 returns only the items where the customer name contains the letters in cell F3.

The formula in cell H3 is:

=FILTER(B3:D10,ISNUMBER(SEARCH(F3,B3:B10)),"No results")

SEARCH returns a number if the search term in cell F3 is found in each value in B3-B10.

ISNUMBER returns TRUE or FALSE for each value depending on if SEARCH returns a number. This TRUE/FALSE value provides the logic needed by FILTER to return the matching items.

In this scenario only, Milkshake Junction and Sunset Satay contain un as a substring, therefore only these customers are returned.

In this guide, we’re going to show you how you can use Excel formula for filtering data.

Syntax

Steps

1. Select the range of cells that will be populated with filtered values

How

To filter out values from a range, we need to pinpoint the cells that meet a certain condition, and retrieve them from the original list. Keep mind that we’re going to need to create an array formula to avoid to creating several helper columns, and use a single Excel formula for filtering data. As a result, the formulas will return array values.

Our example returns values from column B by searching the value of cell E3 in column C. This condition leads to the logical test,

This test returns an array of Boolean values (TRUE and FALSE). For example, if the value of cell E3 is «I», the logical test returns an array like below,

{FALSE;FALSE;TRUE;TRUE;TRUE;…….;FALSE}

These Boolean values become the logical test values for the IF function. The IF function provides the row numbers of cells that meet the criteria, and returns empty strings for others.

The IF function here returns an array. This time an array of row numbers and empty strings.

{«»;»»;3;4;5;…….;»»}

The next step is sorting the row numbers in our new array. The SMALL function can return the nth smallest number from an array. Also note that Excel evaluates string values as almost infinitely large numbers, making any other number small in comparison. This is the reason why the SMALL function is used instead of the LARGE function. To assign an ‘n’ value to the SMALL function, we use the ROW function again with a single cell that should be one cell above the first row to return numbers from 1, and use a relative reference to increase its row number. As a result; SMALL(IF($E$3=C:C,ROW(C:C),»»),ROW()-ROW(E5)) formula returns a row index value which will be used by the INDEX function to return a value from a non-empty cell.

The INDEX function selects the reference to return values, and the IFERROR envelops the nested formula to avoid errors.

Finally, press the Ctrl + Shift + Enter combination instead of just pressing the Enter key to enter your formula as an array formula, and you’re done!
