==FIND(find_text, within_text, [start_num])
=FIND("p","apple ")
The FIND function returns the position of a substring within a string. In the example above, the FIND function returns the number 2, because "p" is the second letter in the string "apple":
=FIND("A","Apple")
The FIND function is case-sensitive, which means it will only return the position of a substring if the substring is all in lowercase or all in uppercase. In the example above, the FIND function returns the number 1, because "A" is the first letter in the string "Apple":
=FIND("a","Apple")
The FIND function is case-sensitive, so it returns a #VALUE! error if you're looking for a lower case letter but only the upper case letter is in the string, or vice versa.
=FIND("x","20 x 30 x 50")
The FIND function can be used to find the position of a substring within a string of text. In the example above, the FIND function returns the number 4, because "x" is the fourth letter in the string "20 x 30 x 50":
The FIND function searches for the text specified by the find_text parameter within the within_text parameter.
