5 Ways To Remove Non-Numeric Characters In Excel

The power of Excel! It's an indispensable tool for many of us, helping us to organize, analyze, and visualize data with ease. However, when working with numerical data, it's not uncommon to encounter non-numeric characters that can throw a wrench in our calculations. Whether it's a stray letter, a symbol, or a space, these unwanted characters can cause errors and frustration. In this article, we'll explore 5 ways to remove non-numeric characters in Excel, making it easier for you to work with clean and accurate data.

The Importance of Clean Data

Before we dive into the methods, it's essential to understand why removing non-numeric characters is crucial. In Excel, formulas and functions rely on numerical data to produce accurate results. When non-numeric characters are present, they can cause errors, return incorrect results, or even prevent formulas from working altogether. By removing these characters, you'll ensure that your data is clean, reliable, and ready for analysis.

Method 1: Using the SUBSTITUTE Function

One of the simplest ways to remove non-numeric characters is by using the SUBSTITUTE function. This function replaces a specified character or string with another character or string. In this case, we'll use it to replace non-numeric characters with nothing, effectively removing them.

Formula: =SUBSTITUTE(A1, " ", "")

• A1 is the cell containing the data with non-numeric characters.
• " " is the space character, which we'll use as a placeholder for all non-numeric characters.
• "" is the replacement string, which is essentially nothing.

By using this formula, you can remove all non-numeric characters from the data in cell A1.

Method 2: Using the REGEX Function (Excel 2019 and Later)

If you're using Excel 2019 or later, you have access to the REGEX function, which provides a powerful way to remove non-numeric characters using regular expressions.

Formula: =REGEXREPLACE(A1, "[^0-9]", "")

• A1 is the cell containing the data with non-numeric characters.
• "[^0-9]" is the regular expression pattern that matches any character that is not a digit (0-9).
• "" is the replacement string, which is essentially nothing.

By using this formula, you can remove all non-numeric characters from the data in cell A1.

Method 3: Using the TEXT TO COLUMNS Feature

Another way to remove non-numeric characters is by using the Text to Columns feature. This feature allows you to split text into separate columns based on a specified delimiter.

Steps:

• Select the cell containing the data with non-numeric characters.
• Go to the Data tab in the ribbon.
• Click on the Text to Columns button in the Data Tools group.
• Choose Delimited Text and click Next.
• Uncheck all the delimiter options and click Finish.

By using this feature, you can remove non-numeric characters from the data by splitting it into separate columns.

Method 4: Using VBA Macro

If you're comfortable with VBA macros, you can create a custom macro to remove non-numeric characters from your data.

Code:

Sub RemoveNonNumericCharacters()
    Dim cell As Range
    For Each cell In Selection
        cell.Value = WorksheetFunction.Substitute(cell.Value, " ", "")
    Next cell
End Sub

• This macro loops through each cell in the selected range and uses the SUBSTITUTE function to remove non-numeric characters.

By using this macro, you can quickly remove non-numeric characters from your data.

Method 5: Using Power Query

If you're using Excel 2010 or later, you have access to Power Query, a powerful data manipulation tool. You can use Power Query to remove non-numeric characters from your data.

Steps:

• Select the cell containing the data with non-numeric characters.
• Go to the Data tab in the ribbon.
• Click on the From Table/Range button in the Get & Transform Data group.
• In the Power Query Editor, click on the Add Column tab.
• Click on the Custom Column button.
• Enter the following formula: = Text.Select([Column1], {"0".."9"})
• Click OK.

By using Power Query, you can remove non-numeric characters from your data.
