InStr

Using the InStr Function

In this tutorial you will learn how to use the InStr Function.

The InStr function returns the position of the first occurrence of a string in another string.

=Instr ( [start], searchin, searchfor, [compare] )

start is optional. It is the starting position for the search. If this parameter is omitted, the search will begin at position 1.

searchin is the string that will be searched.

searchfor is the string to search for.

compare is optional. This is the type of comparison to perform.

In this example we will use a given sentance: "Hello, My name is"
