5 Ways To Find In String With Vba

Mastering the art of finding specific strings within a larger text is a crucial skill for any VBA developer. In this article, we will explore five different methods to find a string within a text using VBA. Whether you are working with Excel, Word, or another application, these techniques will help you become more efficient and effective in your coding endeavors.

Method 1: Using the InStr Function

The InStr function is the most commonly used method to find a string within a text in VBA. It returns the position of the first occurrence of the specified string within the text. The syntax of the InStr function is as follows:

InStr([start], string, substring[, compare])

• [start]: The starting position of the search. If omitted, the search starts from the beginning of the string.
• string: The text to search within.
• substring: The string to search for.
• [compare]: The comparison method. It can be vbBinaryCompare (0), vbTextCompare (1), or vbDatabaseCompare (2).

Example:

Dim text As String
text = "Hello, World!"
If InStr(text, "World") > 0 Then
    MsgBox "Found 'World' in the text."
Else
    MsgBox "'World' not found in the text."
End If

Method 2: Using Regular Expressions (RegEx)

Regular expressions (RegEx) are a powerful tool for finding patterns within a text. VBA has built-in support for RegEx through the VBScript.RegExp object.

Example:

Dim regex As New RegExp
Dim text As String
text = "Hello, World!"
regex.Pattern = "World"
If regex.Test(text) Then
    MsgBox "Found 'World' in the text."
Else
    MsgBox "'World' not found in the text."
End If

Method 3: Using the Like Operator

The Like operator is another way to find a string within a text. It uses a pattern to match the string. The pattern can include wildcards such as *, ?, #, and [charlist].

Example:

Dim text As String
text = "Hello, World!"
If text Like "*World*" Then
    MsgBox "Found 'World' in the text."
Else
    MsgBox "'World' not found in the text."
End If

Method 4: Using the Split Function

The Split function splits a string into an array of substrings based on a specified delimiter. We can use this function to find a string within a text by splitting the text into substrings and then checking if the desired string is in the array.

Example:

Dim text As String
text = "Hello, World!"
Dim substrings() As String
substrings = Split(text, " ")
If UBound(Filter(substrings, "World")) >= 0 Then
    MsgBox "Found 'World' in the text."
Else
    MsgBox "'World' not found in the text."
End If

Method 5: Using the Find Method of the Range Object

In Excel VBA, we can use the Find method of the Range object to find a string within a cell or a range of cells.

Example:

Dim cell As Range
Set cell = Range("A1")
If cell.Find("World") Is Nothing Then
    MsgBox "'World' not found in the cell."
Else
    MsgBox "Found 'World' in the cell."
End If
