7 Excel Tricks For Checking Partial Text In Strings

Excel is a powerful tool that goes beyond simple calculations. Its robust features make it essential for data analysis, especially when it comes to handling strings and text. One common task many users face is checking for partial text in strings, which can be crucial for data validation, filtering, and auditing. Whether you are working with customer names, product descriptions, or any other string data, mastering these tricks can save you time and enhance your Excel skills. Let’s dive into seven effective techniques to check for partial text in strings using Excel.

1. Using the FIND Function

The FIND function is a straightforward way to locate a substring within another string. This function is case-sensitive and returns the starting position of the substring. If the substring isn't found, it returns an error.

Syntax:

=FIND(find_text, within_text, [start_num])

Example:

If you want to find the position of “cat” in the string “The cat is sleeping,” you would use:

=FIND("cat", "The cat is sleeping")

This will return 5, as "cat" starts at the fifth character.

<p class="pro-note">🐾Pro Tip: Use the IFERROR function to handle errors gracefully, such as: =IFERROR(FIND("cat", "The cat is sleeping"), "Not found").</p>

2. Using the SEARCH Function

Similar to the FIND function, the SEARCH function helps find text but is not case-sensitive. This can be beneficial when you want to check for a substring regardless of its casing.

Syntax:

=SEARCH(find_text, within_text, [start_num])

Example:

To check for "CAT" in the string “The cat is sleeping,” use:

=SEARCH("CAT", "The cat is sleeping")

This also returns 5.

<p class="pro-note">🌟Pro Tip: Combine SEARCH with IF to create conditional formulas. For example, =IF(SEARCH("CAT", "The cat is sleeping"), "Found", "Not Found").</p>

3. Using the COUNTIF Function

If you’re looking to check whether a substring exists across a range of cells, COUNTIF is your go-to function. This function counts the number of cells that meet a specific criterion.

Syntax:

=COUNTIF(range, criteria)

Example:

To count how many times “cat” appears in a range A1:A10:

=COUNTIF(A1:A10, "*cat*")

The asterisks (*) act as wildcards, allowing you to count any occurrence of “cat” within those strings.

<p class="pro-note">🔍Pro Tip: Use SUMPRODUCT for a more complex count that could include multiple criteria or conditions.</p>

4. Using the FILTER Function

The FILTER function is great for extracting specific data that meets certain criteria, particularly for partial text checks. This function is available in Excel 365 and Excel 2021.

Syntax:

=FILTER(array, include, [if_empty])

Example:

If you have a list of fruits in A1:A10 and you want to filter out those containing “apple,” you can use:

=FILTER(A1:A10, ISNUMBER(SEARCH("apple", A1:A10)), "No matches found")

This will return only the entries that include “apple”.

<p class="pro-note">✨Pro Tip: Remember that FILTER can also dynamically update as your source data changes, making it powerful for interactive reports.</p>

5. Using Text Functions to Combine

Sometimes, you might want to combine multiple string functions to check for partial matches more efficiently. By concatenating these functions, you can create complex conditions.

Example:

You can create a formula that checks if “cat” is present in A1 and return a custom message:

=IF(ISNUMBER(SEARCH("cat", A1)), "Contains cat", "Does not contain cat")

<p class="pro-note">🌈Pro Tip: Nesting functions increases flexibility, so don’t hesitate to mix functions to suit your needs!</p>

6. Utilizing Data Validation for Text Checks

Data validation can ensure that users only enter data that meets certain conditions. You can set up a validation rule to allow only entries containing a specific text.

Steps:

1. Select the cell(s) you want to validate.
2. Go to Data > Data Validation.
3. In the dialog, choose “Custom” from the Allow dropdown.
4. Enter a formula like:

   =ISNUMBER(SEARCH("cat", A1))
   

5. Set up an error message if the entry does not meet the condition.

<p class="pro-note">⚙️Pro Tip: Data validation helps maintain data integrity and can significantly reduce errors in your Excel sheets!</p>

7. Using the TEXTJOIN Function for Concatenation

The TEXTJOIN function can be invaluable when you want to create a combined string from a list of values that meet a certain criterion.

Syntax:

=TEXTJOIN(delimiter, ignore_empty, text1, [text2], ...)

Example:

If you have a list in A1:A10 and only want to concatenate those that contain “cat”:

=TEXTJOIN(", ", TRUE, IF(ISNUMBER(SEARCH("cat", A1:A10)), A1:A10, ""))

This will give you a single string of all items containing “cat”.

<p class="pro-note">💡Pro Tip: Use TEXTJOIN instead of CONCATENATE for better performance with large datasets!</p>
