How to use the Find Function in Google Sheets
Returns the position at which a string is first found within text.
The FIND function in Google Sheets is used to locate the position of a specified text string within another text string. This function is case-sensitive and is particularly useful for text parsing, data validation, and complex manipulations involving text.

Benefits of Using the FIND Function
- Text Analysis: Allows for detailed parsing and analysis of text data, which is essential for processing large datasets.
- Data Validation: Helps in validating text fields by checking for the presence of specific characters or substrings.
- Complex String Manipulations: Facilitates operations that require precise string handling, such as extracting substrings or splitting text based on certain criteria.
- Case Sensitivity: Provides precise text searches where case sensitivity is crucial, distinguishing it from similar functions like SEARCH.
Step-by-Step Guide
Step 1: Understanding the Syntax
- FIND(search_for, text_to_search, [starting_at])
- search_for: The text to find.
- text_to_search: The text within which to search.
- [starting_at]: Optional. The position in text_to_search at which to start the search. Default is 1 (the beginning of the text).
Step 2: Preparing Your Data
Ensure your spreadsheet contains the text data in which you plan to use the FIND function. Data should be organized clearly to facilitate easy access and manipulation.
Step 3: Applying the FIND Function
1. Select the Output Cell: Click on the cell where you want the result of the FIND function to appear.
2. Input the Function: Enter =FIND(, followed by the parameters for your specific search.

Example
Scenario: Processing and Validating Product Codes
Imagine you are managing inventory for a company that uses specific product codes to identify items. Each product code follows a format where the first two characters indicate the product category, followed by a dash, and then a unique identifier number. For example, "PR-12345". You need to verify that each product code follows this format and extract the category code for further analysis.
Data Setup:
- A1: Product Code
- B1: Format Valid
- C1: Category Code
- Rows 2-100: Data for various product codes.
Objective:
Use the FIND function to verify the format of each product code and extract the category code for valid entries.
Step 1: Organize Your Spreadsheet
Ensure your spreadsheet is populated with the product codes that need to be validated and analyzed.
Step 2: Validate Product Code Format
1. B2: Use the FIND function to check for the presence of the dash ("-") at the correct position (the third character) in the product code:
=IF(ISNUMBER(FIND("-", A2)), IF(FIND("-", A2) = 3, "Valid", "Invalid"), "Invalid")
This formula first checks if a dash is present using ISNUMBER combined with FIND. It then checks if the dash is in the third position, marking the code as "Valid" if both conditions are met, otherwise "Invalid".
2. Drag the formula down from B2 to B100 to apply it to all listed product codes.

Step 3: Extract Category Code
1. C2: Extract the category code from valid product codes:
=IF(B2="Valid", LEFT(A2, FIND("-", A2) - 1), "N/A")
This formula uses LEFT and FIND to extract the category code (the substring before the dash) only if the product code format is valid as per column B.
2. Drag the formula from C2 to C100 to apply it across your product list.
Advanced Tips
- Error Handling: Combine FIND with IFERROR to handle cases where the "@" symbol is not found, thus avoiding error values in your results:
=IFERROR(FIND("@", A2), "Not found")
- Conditional Formatting: Apply conditional formatting to email addresses that do not contain the "@" symbol by using a custom formula based on the ISERROR function:
=ISERROR(FIND("@", A2))
- Extracting Usernames: Use FIND to help extract the username from the email address by combining it with the LEFT function:
=LEFT(A2, FIND("@", A2)-1)
- Dynamic Searches: Allow dynamic input for the search_for parameter by linking it to another cell where users can specify the character or string they want to find.
