Excel: The Difference Between SEARCH vs. FIND Functions

In the expansive toolkit of Microsoft Excel, manipulating and analyzing data often requires pinpointing specific characters or patterns within larger blocks of text. Both the SEARCH function and the FIND function are designed to locate the starting position of one text string within another. While their core purpose is identical—returning a numerical position—they are fundamentally
