Extract all Partial Matches

Just assume that you have a range of data that contains a text string and you want to extract the few partial matches into another separate range of cells; then you might think that it’s not a big deal; because you would prefer to manually extract the few partial matches into another separate range of cells without any need of the formula;

Then congratulations because you are thinking right, but let me add up that it would be a big deal to extract the multiple partial matches into another separate range of cells and doing it manually would be a foolish attempt because you would get tired of it and would never complete your work on time.

But don’t be worry about it because after carefully reading this article, extracting multiple partial matches into another range of cells would become a piece of cake for you.

So let’s dive into the article to take you out of this fix.

General formula


The Following formula would help you out for extracting multiple partial matches into another separate range of cells:

=INDEX($B$1:$B$5,AGGREGATE(15,6,(ROW($B$1:$B$5)-ROW($B$1)+1)/ISNUMBER(SEARCH($D$1,$B$1:$B$5)),E2))

Syntax Explanations


Before going into the explanation of the formula for getting the work done efficiently, we must understand each syntax which would make it easy for you that how each syntax contributes to extracting multiple partial matches into a separate range or list of cells:

  • INDEX: In a range or array, this index function contributes to returning the value at a given position.
  • AGGREGATE: This function contributes to returning the aggregate result in a database or list of values in the excel sheet.
  • ROW: In Excel, this Row function contributes toreturning the row number as a reference.
  • Absolute Reference: The Absolute referenceis nothing but an actual fixed location in a worksheet.
  • ISNUMBER: This function contributes to returns TRUE when a cell contains a number and FALSE if there is no number.
  • SEARCH: This function contributes to locating the character between two text strings and returns to the number of the starting position of the first text string from the first character of the second text string.
  • Comma symbol (,): In Excel, this comma symbol acts as a separator that helps to separate a list of values.
  • Minus Operator (-): This minus symbol contributes to subtracting any two values.
  • Parenthesis (): The core purpose of this Parenthesis symbol is to group the elements and to separate them from the rest of the elements.
  • Plus operator (+): This plus operator adds the values.
  • Division (/): This division symbol is used for dividing values or numbers.

Let’s See How This Formula Works:


The INDEX function is the primary function having AGGREGATE, which is highly useful to figure out the matches for each row in the extracted area:

=INDEX($B$1:$B$5,matched_values)

Almost all of the work is to determine and report which rows in “$B$1:$B$5” match the search string and report the position of each matching value to INDEX. This is accomplished by configuring the AGGREGATE function as follows:

=AGGREGATE(15,6,(ROW($B$1:$B$5)-ROW($B$1)+1)/ISNUMBER(SEARCH($D$1,$B$1:$B$5)),E2)

extract all partial matches1

The very first input or argument, which is 15, instructs AGGREGATE to return the nth smallest values.

The second argument, 6, specifies whether or not to ignore mistakes.

The third argument is an expression that returns an array of results that match.

The fourth input, E2, it specifies the “nth” value.

AGGREGATE works on arrays, and for the third argument inside AGGREGATE, the expression below builds an array :

={(ROW($B$1:$B$5)-ROW($B$1)+1)/ISNUMBER(SEARCH($D$1,$B$1:$B$5))}}

extract all partial matches1

In this case, the ROW function is used to build an array of relative row numbers, as that’s why SEARCH and ISNUMBER are combined to match the search string against values in the data, resulting in an array of TRUE and FALSE values.

TRUE behaves as 1 in this math operation, while FALSE behaves as 0. As a result, row numbers with a positive match are divided by 1 and survive the operation, whereas row numbers with non-matching values are destroyed and become #DIV/0 errors. AGGREGATE is configured to ignore errors; it ignores #DIV/0 errors and returns the “nth” smallest number from the remaining values.

Alternative Formula with SMALL Function


You can also use an alternative formula which is based on SMALL function and IF Function to achieve the same result:

=INDEX($B$1:$B$5,SMALL(IF(ISNUMBER(SEARCH($D$1, $B$1:$B$5)),ROW($B$1:$B$5)-ROW($B$1)+1),E2))

Note: this is an array formula, and to get the work done, please enter it with Control + Shift + Enter.
