This article describes the formula syntax and usage of the SEARCH and SEARCHB functions (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.


The SEARCH and SEARCHB functions locate one text string within a second text string, and return the number of the starting position of the first text string from the first character of the second text string. For example, to find the position of the letter "n" in the word "printer", you can use the following function:


This function returns 4 because "n" is the fourth character in the word "printer."

You can also search for words within other words. For example, the function


returns 5, because the word "base" begins at the fifth character of the word "database". You can use the SEARCH and SEARCHB functions to determine the location of a character or text string within another text string, and then use the MID and MIDB functions to return the text, or use the REPLACE and REPLACEB functions to change the text. These functions are demonstrated in Example 1 in this article.

 Important   SEARCHB counts 2 bytes per character only when a DBCS language is set as the default language. Otherwise SEARCHB behaves the same as SEARCH, counting 1 byte per character.

The languages that support DBCS include Japanese, Chinese (Simplified), Chinese (Traditional), and Korean.



The SEARCH and SEARCHB functions have the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):

  • find_text    Required. The text that you want to find.
  • within_text    Required. The text in which you want to search for the value of the find_text argument.
  • start_num    Optional. The character number in the within_text argument at which you want to start searching.


  • The SEARCH and SEARCHB functions are not case sensitive. If you want to do a case sensitive search, you can use FIND and FINDB.
  • You can use the wildcard characters — the question mark (?) and asterisk (*) — in the find_text argument. A question mark matches any single character; an asterisk matches any sequence of characters. If you want to find an actual question mark or asterisk, type a tilde (~) before the character.
  • If the value of find_text is not found, the #VALUE! error value is returned.
  • If the start_num argument is omitted, it is assumed to be 1.
  • If start_num is not greater than 0 (zero) or is greater than the length of the within_text argument, the #VALUE! error value is returned.
  • Use start_num to skip a specified number of characters. Using the SEARCH function as an example, suppose you are working with the text string "AYF0093.YoungMensApparel". To find the position of the first "Y" in the descriptive part of the text string, set start_num equal to 8 so that the serial number portion of the text (in this case, "AYF0093") is not searched. The SEARCH function starts the search operation at the eighth character position, finds the character that is specified in the find_text argument at the next position, and returns the number 9. The SEARCH function always returns the number of characters from the start of the within_text argument, counting the characters you skip if the start_num argument is greater than 1.


Example 1: SEARCH

Use the embedded workbook shown here to work with examples of this function. You can inspect and change existing formulas, enter your own formulas, and read further information about how the function works.

To work in-depth with this workbook, you can download it to your computer and open it in Excel. For more information, see the article Download an embedded workbook from OneDrive and open it on your computer.

Example 2: SEARCHB

 Important    Your regional settings must be set to a language that supports DBCS for this example to work.

In the following example:

  • The SEARCHB function returns 3 because each character is counted by its bytes; the first character has 2 bytes, so the second character begins at byte 3.
  • SEARCH returns 2 because "Tokyo to Shibuya " is in the second position within the string. SEARCH returns 2 regardless of the default language setting.

=SEARCHB("Tokyo to Shibuya ","Tokyo to Shibuya Tokyo to Shibuya Tokyo to Shibuya ") equals 3

=SEARCH("Tokyo to Shibuya ","Tokyo to Shibuya Tokyo to Shibuya Tokyo to Shibuya ") equals 2
