2. Using Native Excel Functions and VBA

If you prefer to use native Excel functions, here is how you can address the problem:

Open your Excel workbook: Load the file containing the text entries you need to extract patterns from.
Use VBA to leverage Regex capabilities: Excel’s built-in functions do not directly support Regex, but you can use VBA for this purpose.

Step-by-Step Solution Using VBA with Regex:

Open the VBA editor: Press Alt + F11 to open the VBA editor.
Insert a new module: Click Insert > Module.
Enter the VBA code: Use the following code to extract patterns using Regex:

Function ExtractPattern(cell As Range, pattern As String) As String
    Dim regEx As Object
    Set regEx = CreateObject("VBScript.RegExp")
    regEx.Pattern = pattern
    regEx.Global = True
    regEx.IgnoreCase = False ' Change to True if case insensitive match is needed
    If regEx.Test(cell.Value) Then
        ExtractPattern = regEx.Execute(cell.Value)(0).Value
    Else
        ExtractPattern = ""
    End If
End Function

Apply the function: Use the custom function ExtractPattern in your worksheet.

Example:

=ExtractPattern(A1, "\b\w{5}\b")

This formula extracts the first 5-letter word from cell A1.

Drag the formula: Apply the formula to other cells as needed.

Difficulties and Limitations:

Manual setup required for each pattern extraction.
High risk of errors if the pattern setup is incorrect.
Limited flexibility compared to SheetFlash; combining functions can result in very long and unreadable formulas.
