How to Use the SEARCH Function in Excel (Case-Insensitive Search) The SEARCH() function is used to find the position of a substring within a text string, ignoring case. This makes it extremely useful for flexible text searches. 📘 Syntax: =SEARCH(find_text, within_text, [start_num]) ✅ Example: =SEARCH("x","Excel") This returns 1, even though "x" in "Excel" is lowercase and "X" was lowercase too — it's case-insensitive. 🎯 Use Cases: Searching for keywords in a text column Flexible matching for data validation Extracting text parts based on keyword positions 💡 Difference from FIND: Unlike FIND() , SEARCH() doesn't care about uppercase or lowercase letters — perfect for general-purpose matching.
