How to find if an array contains a string

📝 Finding if an Array Contains a String: Easy Solutions for Common Issues 🕵️‍♀️

Have you ever found yourself in a situation where you needed to check if an array contains a specific string? 🤔 Perhaps you're working on an Excel macro or some VBA code, and you couldn't figure out the right syntax or encountered some error messages. 😩 Don't worry, we've got you covered! In this blog post, we'll walk you through some easy solutions to common issues that people face when trying to find if an array contains a string. Let's dive in! 💪

The Problem 🚫⁉️

One example of the problem we'll be addressing is a situation where you have an array and you want to check if it contains a certain string. You might be tempted to use a simple function like array.contains(mystring) as shown in the code snippets provided. But if you've tried that, you may have encountered error messages like "Invalid Qualifier" or "Object Required." 😱

Solution 1: Using a Loop 🔄

One way to solve this problem is by using a loop, just like in the code snippets you shared. 🔄

Here's an example of how you can modify your code to make it work:

For Each cel In Selection
    For Each item In Mainfram
        If item = cel.Value Then
            ' Do something
        End If
    Next item
Next cel

In this solution, we iterate over each element in the array (Mainfram) and compare it with the value of the current cell (cel.Value). If we find a match, we can perform the desired action.

Solution 2: Using the Filter Function 🔍

Another approach to finding if an array contains a string is by using the Filter function in VBA. 🆎

Here's an example of how you can modify your code to implement this solution:

For Each cel In Selection
    If UBound(Filter(Mainfram, cel.Value)) > -1 Then
        ' Do something
    End If
Next cel

In this solution, we use the Filter function to filter the Mainfram array based on the value of the current cell (cel.Value). If the filtered array has a higher upper bound than -1 (indicating that it contains elements), we can perform the desired action.

Solution 3: Using a Custom Function 💡

If you find yourself frequently needing to check if an array contains a string, you can create a reusable custom function. 🔄

Here's an example of how you can define a custom function to check if a string exists in an array:

Function IsInArray(stringToBeFound As String, arr As Variant) As Boolean
    IsInArray = (UBound(Filter(arr, stringToBeFound)) > -1)
End Function

With this custom function in place, you can use it in your code like this:

For Each cel In Selection
    If IsInArray(cel.Value, Mainfram) Then
        ' Do something
    End If
Next cel

This solution not only simplifies your code but also enhances its readability by abstracting away the implementation details of checking array containment.

Time to Shine! 🌟

Now that you've learned some easy solutions to find if an array contains a string, it's time to put your newfound knowledge into practice! 🚀 Whether you choose to use a loop, the Filter function, or create a custom function, remember to adapt the solutions to fit your specific requirements.
