With classic regular expressions, anything outside a capturing group is not included in the extraction. No one knows why VBA RegEx works differently and captures "@" as well. To get rid of it, you canremove the first characterfrom the result by replacing it with an empty string. =REPLACE(...
If you have single-line strings that only contain normal spaces (value 32 in the 7-bit ASCII system), it does not really matter which of the below regexes you use. In case of multi-line strings, it does make a difference. To remove everythingafter a space character, use this regex: ...
In the previous examples, you’ve learned to usegrepto search for lines that contain a specific string. In those examples, the regex engine matched characters or a string. On the other hand, Anchors do not match any character at all. Anchors match a position before and after characters. Th...

Set (remove duplicates): The captures are appended to the input as a set of strings. Note that duplicates are removed and the order of captures is not preserved. Output column prefix Define what prefix should be used for the output column names: ...
RegEx can be super helpful in many cases. To cut it short, the objective is to match a certain pattern and return all the values in the text that match the criteria. The output of RegEx also depends on what type of match you’re looking for, i.e., should it contain a pattern, exa...
RE/flex also allows you to convert expressive regex syntax forms such as\pUnicode classes, character class set operations such as[a-z--[aeiou]], escapes such as\X, and(?x)mode modifiers, to a regex string that the underlying regex library understands and will be able to use: ...
This constant specifies that a character in aPatternand a character in the input string only match if they are canonically equivalent. CaseInsensitive2 This constant specifies that aPatternis matched case-insensitively. Comments4 This constant specifies that aPatternmay contain whitespace or comments....
