REGEXTEST function
The REGEXTEST function is one of the text and data functions. Is used to check whether any part of supplied text matches a regular expression pattern, returning TRUE or FALSE.
Syntax
REGEXTEST(text, pattern, [case_sensitivity])
The REGEXTEST function has the following arguments:
| Argument | Description |
|---|---|
| text | The text string or reference to a cell containing the text you want to test against the pattern. |
| pattern | The regular expression ("regex") that describes the pattern of text you want to match. |
| case_sensitivity | Determines whether the match is case-sensitive. It is an optional argument. If omitted, the match is case-sensitive (0). Enter 0 for case-sensitive matching or 1 for case-insensitive matching. |
Notes
When writing regex patterns, symbols called "tokens" can be used that match with a variety of characters. These are some simple tokens for reference:
- [0-9]: any numerical digit
- [a-z]: a character in the range of a to z
- [A-Z]: a character in the range of A to Z
- .: any single character
- *: zero or more of the preceding character
- +: one or more of the preceding character
- ^: start of the string
- $: end of the string
- \: escape character (e.g., \( matches a literal parenthesis)
- {n}: exactly n occurrences of the preceding character
The function returns TRUE if the pattern matches any part of the text, and FALSE if no match is found.
