The entire scope of program is given below. Step 7: Running the foreach loop to find the match throughout the given string variable. Set theMatches = regexOne.Execute(stringOne) Step 6: Setting the match for the regex variable. Here in the below program we have set a pattern for “A.C” so find all the possible matches that includes A.C (A, any character, c). Step 5: Define the regex pattern and methods as per the program’s demand. Step 4: Set the object for Regex variable. Now, we can access this Regex object in the VBA coding. Step 3: Now click on OK button on the right side of the dialog box. Scroll down and select the “Microsoft VBScript Regular Expression 5.5” option. Step 2: The VBA references option list will appear to the VBA Project.

Go to Tools and select the References option to enable the Regex functionality. Step 1: Open the Visual Basic Editor by pressing Alt + F11. The steps to create Regex in VBA are as follows: Execute (search-string) – This operations returns all matches of the pattern computed against the search-string.Replace (search-string, replace-string) – This operation replaces the occurrences of the pattern in search-string with replace-string.Test (string) – This operation returns a Boolean True if the pattern gets matched against the given string.The Regular Expression object has the following 3 operations: MultiLine – This property helps to match the pattern across line breaks.If it is set to Boolean false, it only matches the first found pattern. Global – This property finds all the possible matches in the input string.It will only match the pattern in the string irrespective of its case. IgnoreCase – This property will ignore the letter case (upper case/ lower case).Pattern – It represents the pattern with regex expression that you want to match against.The Regular Expression object has the following four properties: It represents values between “n” and “m” times and matches as few as possible values. It signifies zero or once and matches as few as possibleĪt least “n” times (non-GREEDY). If it is zero or once it matches as many as possible It represents one or more of values and matches as many as possible values. It matches as many as values as possible. The quantifiers are used to specify the number of times the user wants to match the pattern against the string. This expression represents the Carriage and returns a new line (vbNewLine). This expression represents the Tab value (vbTab) This expression is followed by any special character – escapes special characters. It represents all characters except non-decimal digit.

It represents any decimal digit in between 0-9. It represents any non-white space character It would match “c” in represents any non-word character. It represents the word character including alphabets, modifiers, digits, punctuation and connectors. It matches any character belonging to the character range specified between brackets It is used to match the characters that are not being one of the provided between brackets It matches the given characters present in between the brackets. It signifies all the characters except vbNewLine (newline). The Regex expressions are evaluated through matching expressions and Quantifiers. Regular Expressions are often used to are used to validate website input or user input matches with the data, search for word patterns in large strings/texts with a specific pattern. Excel offers quite a bit of text functions, but none of them can compare with regular expressions.

They are necessarily a sequence of characters that act as a search algorithm and matches the pattern. They are supported in many languages, including. Regex stands for Regular Expression is basically a pattern matching strings within another string.
