What Is the Excel FIND Function?
Excel’s FIND function returns the position, as a number, where a specified character or text string first appears within another text string. It is like finding a needle in a haystack: FIND tells you the exact location of the needle you want within the haystack of text. The FIND function plays a key role in many Excel tasks, including text analysis, data cleanup, and conditional formatting. When combined with other text functions, it can provide even more powerful functionality. For example, FIND makes it easy to split text using a specific delimiter or identify cells that contain a particular keyword.
Basic FIND Function Syntax and Usage
The FIND function has relatively simple, easy-to-use syntax. Its basic syntax is as follows:
=FIND(find_text, within_text, [start_num])The arguments are as follows:
- find_text: A required argument that specifies the character or text string to find, enclosed in double quotation marks (“”). For example, enter the exact text you want to find, such as “A” or “apple”.
- within_text: A required argument that specifies the cell containing the text to search or a text string entered directly.
- [start_num]: An optional argument that specifies, as a number, where to begin searching within within_text. If omitted, the default value is 1, and the search begins at the start of the string. This is useful when you want to search from a specific position onward. Note, however, that a [start_num] value less than or equal to 0 returns a #VALUE! error. A value greater than the length of within_text also returns a #VALUE! error.
For example, if cell A1 contains the text “Hello World,” the following formula returns the position of the character “W”:
=FIND("W", A1)The formula returns 7 because “W” is the seventh character in “Hello World.” Importantly, spaces are also counted as characters.
Key FIND Function Feature: Case Sensitivity
One of the most important features of the FIND function is that it is strictly case-sensitive. In other words, it finds only text that exactly matches the uppercase and lowercase letters specified in find_text. Therefore, searching for “A” and searching for “a” produce entirely different results. This characteristic is especially useful for tasks that require data accuracy. If you want to search without distinguishing between uppercase and lowercase letters, consider using the SEARCH function. FIND’s strict case sensitivity is valuable when you need to identify subtle differences in data.
Differences Between the FIND and SEARCH Functions
The SEARCH function also finds the position of text within a string. The main differences between the two functions are case sensitivity and wildcard support. As mentioned above, FIND is strictly case-sensitive, while SEARCH is not case-sensitive. In addition, SEARCH supports wildcard characters (* and ?) for pattern-matching searches, whereas FIND supports only exact text-string matches. For example, SEARCH(“s?t”, “sat”) can find both “sat” and “set,” while SEARCH(“s*d”, “sad”) can find not only “sad” but also “started.” If you want to search for a wildcard character itself, use a tilde (~) in the SEARCH function. Therefore, it is important to choose the appropriate function based on your search requirements.
| Feature | FIND Function | SEARCH Function |
| Case sensitivity | Case-sensitive | Not case-sensitive |
| Wildcard support | Not supported | Supported (*, ?) |
6. Practical Examples of the FIND Function
The FIND function is useful on its own, but it becomes even more powerful when used with other Excel functions. Let’s examine a few practical examples of how to use FIND.
- Extracting specific text with MID, LEFT, and RIGHT: After using FIND to identify the position of a specific character, you can combine it with MID, LEFT, or RIGHT to extract exactly the portion of text you need.
* Example 1: If cell A1 contains an email address, the following formula extracts the username before the @ symbol:
=LEFT(A1, FIND("@", A1)-1)
In this formula, FIND("@", A1) finds the position of the @ symbol in cell A1. Subtracting 1 gives the number of characters before the @ symbol. The LEFT function extracts that number of characters starting from the left side of cell A1.
* Example 2: Likewise, the following formula extracts the domain name after the @ symbol in an email address:
=MID(A1, FIND("@", A1)+1, LEN(A1)-FIND("@", A1))
Here, FIND("@", A1)+1 specifies that text extraction should begin after the @ symbol, and LEN(A1)-FIND("@", A1) calculates the length of the domain name by subtracting the position of the @ symbol from the total email address length. The MID function extracts the specified number of characters from the specified position in cell A1.
- Checking whether a specific string exists with IF: FIND returns the position as a number when the text exists and returns a #VALUE! error when it does not. By combining this behavior with IF, you can check whether a particular text string exists as a logical value (TRUE or FALSE). Using ISNUMBER as well allows you to get the desired result even when an error occurs.
* Example: The following formula checks whether cell A1 contains a specific word:
=IF(ISNUMBER(FIND("specific word", A1)), "Included", "Not included")
FIND("specific word", A1) looks for "specific word" in cell A1. If found, it returns its position as a number; otherwise, it returns a #VALUE! error. ISNUMBER returns TRUE when the FIND result is a number and FALSE when it is an error. Based on this result, IF displays either "Included" or "Not included."
- Finding the nth occurrence of a string with SUBSTITUTE: FIND can locate only the first occurrence of a specific character in a text string. If a specific character appears multiple times and you want to find its nth occurrence, you can use it with SUBSTITUTE. First, use SUBSTITUTE to temporarily replace the nth occurrence with another character, and then use FIND to locate that character.
* Example: To find the third occurrence of "find_text" in cell A1, you can use the following formula:
=FIND("!", SUBSTITUTE(A1, "find_text", "!", 3))
SUBSTITUTE(A1, "find_text", "!", 3) replaces the third occurrence of "find_text" in cell A1 with "!". FIND("!",...) then finds the position of "!" in the modified string, which is the position of the third occurrence of "find_text" in the original string.
Advanced Searches Using the Start Position Argument
Using the third FIND argument ([start_num]) lets you begin a search from a specific position to get the result you need. For example, it is useful when a text string contains a character more than once and you want to find the second or later occurrence.
For example, if cell A1 contains the text “apple pie and apple juice,” you can use the following formula to find the position of the second “apple”:
=FIND("apple", A1, FIND("apple", A1)+1)
This formula first finds the position of the first “apple” with FIND(“apple”, A1), then uses that position plus 1 as the third argument to search for “apple” again. As a result, the second FIND function begins its search after the first “apple” and returns the position of the second “apple.”
Tips for Using FIND in Excel at Work
The FIND function can be useful in a variety of workplace situations. Here are a few practical tips.
- Use it for data validation: You can use FIND to set up data validation so that only data containing a specific character or format can be entered. For example, to require an @ symbol in an email address, enter the following formula in a custom data validation rule:
=ISNUMBER(FIND("@", A1))
(Here, A1 is the cell to validate.) Similarly, FIND can be used to validate data that must follow a particular format, such as a Korean resident registration number containing 14 characters including a hyphen. For example, the formula to check whether the resident registration number entered in cell A1 has 14 characters including a hyphen, with the hyphen in the seventh position, is "=AND(LEN(A1)=14,FIND("-",A1)=7)".
- Use it for text data cleanup: FIND can identify, remove, or modify data that contains unnecessary characters or specific patterns. For example, you can use FIND with SUBSTITUTE to find a delimiter in text and split the text based on that delimiter or replace it with another character.
- Actively combine it with other functions: As shown in the examples above, FIND becomes more powerful when used with other text and logical functions. Combining functions allows you to perform complex text-processing tasks efficiently. For example, it can also be used with TEXT to convert numbers into a specific text format or with CONCATENATE or the & operator to join multiple text strings [5].
Excel FIND Function Precautions and Error Solutions
It is important to understand the major errors that can occur when using FIND and how to resolve them.
- Main causes and solutions for #VALUE! errors: The most common error when using FIND is the #VALUE! error. It usually occurs in the following situations:
find_text is not in within_text:
If the text you are looking for does not exist in the text being searched, a #VALUE! error occurs. This may result from a case mismatch, a spelling error, or simply because the search string is not in the target string. In this case, carefully check the capitalization and spelling of the text to find, and confirm that it actually exists in the string being searched.
The [start_num] argument is invalid:
If [start_num] is 0 or less, or greater than the length of within_text, a #VALUE! error occurs. [start_num] must always be a positive integer of 1 or greater and must be less than or equal to the length of the text being searched.
find_text is an empty string (""):
If you specify an empty string ("") for find_text, FIND attempts to find the first character of the search text, which can lead to an unexpected #VALUE! error. In this case, specify a valid search term for find_text.
- Potential issues caused by case sensitivity: Because FIND is strictly case-sensitive, it is important to maintain consistent capitalization in your data [2]. If you need to search without case sensitivity, consider using UPPER or LOWER to standardize the capitalization of both the text being searched and the text to find.
- Handle errors with IFERROR: Because FIND may return a #VALUE! error, you can use IFERROR to return a specific value or message when an error occurs. For example, the formula “=IFERROR(FIND(find_text, A1), “Text not found”)” displays “Text not found” instead of a #VALUE! error when it cannot find “find_text” in cell A1.
Extended Uses of the Excel FIND Function
In addition to its basic text-position search capabilities, FIND can be used in a variety of advanced scenarios.
- Use in array formulas: FIND can be powerful in array formulas. Array formulas let you check conditions across multiple cells at once and perform complex tasks, such as counting cells that contain specific text or calculating the sum of data that meets specific criteria. For example, to count the cells containing the word “Seoul” in the range A1:A10, enter the array formula “=COUNT(FIND(“Seoul”, A1:A10))” and press Ctrl + Shift + Enter.
- Use in conditional formatting: FIND can be used in conditional formatting rules to apply formatting to cells or rows containing specific text. For example, if you want to find the keyword entered in cell C2 in each cell in column B and highlight every row containing that keyword, you can use a conditional formatting formula such as “=FIND(C2, B5)>0” in the “Use a formula to determine which cells to format” rule and specify the desired format. Here, C2 is an absolute reference to the cell containing the keyword, and B5 is a relative reference to the first data cell to format.
- Use in VBA: In Excel VBA (Visual Basic for Applications), you can use the Find method, which provides functionality similar to the FIND function, to search for and manipulate specific text strings. With VBA code, you can automate tasks such as locating a cell containing the word “Product Name” on a specific worksheet and checking its location or performing other actions. For example, the following VBA code searches for “Product Name” on the “Sheet1” worksheet and displays the address of the matching cell in a message box.
Dim findText As String
findText = "Product Name"
Dim foundCell As Range
Set foundCell = Sheets("Sheet1").Cells.Find(What:=findText, LookIn:=xlValues, LookAt:=xlPart, MatchCase:=False)
If Not foundCell Is Nothing Then
MsgBox "Found: " & foundCell.Address
Else
MsgBox "Text not found."
End If
