7 Easy Ways To Find The First Number In A String Using Excel

Finding the first number in a string using Excel can be a useful skill, whether you're dealing with large datasets, cleaning up data entries, or simply trying to extract useful information from a bunch of mixed content. If you've ever found yourself sifting through text-heavy cells filled with unnecessary characters, you know how frustrating it can be to isolate that valuable numerical data! 😅 Luckily, Excel offers several ways to tackle this problem.

In this post, we’ll explore seven easy methods to find the first number in a string using Excel. We'll guide you through each method, share helpful tips, and point out some common mistakes to avoid. Let’s jump right in! 🚀

Method 1: Using a Formula

The most direct approach is to use a formula that combines a few Excel functions. Here’s a handy formula to get you started:

=LOOKUP(1,-MID(A1,ROW($1:$100),1))

How it Works:

• MID(A1,ROW($1:$100),1) extracts each character in the string.
• LOOKUP(1, ...) then retrieves the last numeric character found.

Important Note

<p class="pro-note">Use CTRL+SHIFT+ENTER to enter the formula as an array formula if you're using older versions of Excel.</p>

Method 2: Using Array Formula

Another efficient way to find the first number is through an array formula that combines several functions:

=MIN(IF(ISNUMBER(VALUE(MID(A1,ROW($1:$100),1))), ROW($1:$100)))

Steps:

1. Enter this formula into your Excel cell.
2. Don’t forget to press CTRL+SHIFT+ENTER.

Important Note

<p class="pro-note">Make sure that your data doesn’t contain leading spaces as it could affect the outcome.</p>

Method 3: Utilizing TEXTJOIN in Excel 365

If you’re using Excel 365, TEXTJOIN can simplify your life:

=TEXTJOIN("", TRUE, IF(ISNUMBER(--MID(A1, ROW(1:100), 1)), MID(A1, ROW(1:100), 1), ""))

Explanation:

• This formula joins all characters that are numbers into a single string.

Important Note

<p class="pro-note">Ensure that your Excel version supports TEXTJOIN; otherwise, you'll receive an error.</p>

Method 4: Using VBA for Automation

If you often need to extract numbers, consider creating a VBA function:

1. Press ALT + F11 to open the VBA editor.
2. Insert a new module.
3. Paste the following code:

Function FirstNumber(rng As Range) As Double
    Dim i As Integer
    For i = 1 To Len(rng.Value)
        If IsNumeric(Mid(rng.Value, i, 1)) Then
            FirstNumber = Mid(rng.Value, i, 1)
            Exit Function
        End If
    Next i
    FirstNumber = 0
End Function

Usage:

Now, in your Excel sheet, simply call =FirstNumber(A1).

Important Note

<p class="pro-note">Make sure to save your Excel file as a macro-enabled workbook to keep the function.</p>

Method 5: Using Power Query

Power Query allows you to transform your data quickly.

1. Select your data, and navigate to the Data tab.
2. Click on Get & Transform Data.
3. Load your data into Power Query.
4. Use the Extract function to pull numbers from the text.

Important Note

<p class="pro-note">Power Query is available in Excel 2010 and later versions but works best in 2016 and above.</p>

Method 6: Using Filters

If you just want to visually scan for the first number in your data:

1. Apply a filter to your data range.
2. Set a text filter for cells that contain numbers.

Important Note

<p class="pro-note">Remember that this method won't isolate the numbers, but it can help you find them quickly for manual extraction.</p>

Method 7: Using Flash Fill

For Excel users with newer versions, Flash Fill can be a lifesaver.

1. Start typing the desired output adjacent to your string.
2. Excel will suggest auto-complete options; just press Enter to accept the suggested fill.

Important Note

<p class="pro-note">Make sure the first instance you type is consistent with your desired pattern for Flash Fill to work effectively.</p>

Troubleshooting Common Issues

While applying these methods, you may encounter some roadblocks. Here are a few common mistakes and how to troubleshoot them:

• Formula Errors: Double-check if you've entered the formula correctly, especially if it's an array formula that requires CTRL + SHIFT + ENTER.
• Mixed Data Types: Ensure your string doesn't contain unexpected characters that might hinder the numerical extraction.
• Excel Version Compatibility: Some functions may not work in older versions of Excel; make sure your functions are supported.
