Searches a character expression for a string of characters
-
source
-
specifies the character expression to search.
-
excerpt
-
specifies the string of characters to search
for in the character expression.
| Tip: |
Enclose a literal string
of characters in quotation marks. |
The INDEX function searches source, from left to right, for the first occurrence of the
string specified in excerpt, and returns the
position in source of the string's first character.
If the string is not found in source, INDEX
returns a value of 0. If there are multiple occurrences of the string, INDEX
returns only the position of the first occurrence.
