In VBA (Visual Basic for Applications), the InStrRev function is used to search for a substring within a string, but it starts searching from the end of the string instead of the beginning. It returns the position of the first occurrence of a specified substring in the string, searching from the end to the start. This is essentially the reverse of the InStr function
