10 Easy Excel Tricks To Remove Non-Alphanumeric Characters

If you’ve ever found yourself grappling with messy data in Excel filled with non-alphanumeric characters, you're not alone! 🥴 Whether it’s from importing data from the web or receiving messy spreadsheets from coworkers, cleaning up your data can be a daunting task. Thankfully, there are several easy tricks you can employ to quickly remove those unwanted characters. Let's dive into these 10 handy Excel tricks that will make your data clean-up a breeze! 🌟

Understanding Non-Alphanumeric Characters

Before we dive into the tricks, it's essential to understand what we mean by non-alphanumeric characters. In simple terms, these are any characters that are not letters (A-Z, a-z) or numbers (0-9). This can include symbols like !@#$%^&*(), punctuation marks, spaces, and more. Keeping your data free of these characters can improve the accuracy of your analysis and reporting.

1. Using the SUBSTITUTE Function

One of the simplest ways to remove non-alphanumeric characters is to use the SUBSTITUTE function. This function allows you to replace specific characters in a text string.

Example:

=SUBSTITUTE(A1, "#", "")

This formula will remove the '#' character from the string in cell A1. You can nest multiple SUBSTITUTE functions to remove more characters:

=SUBSTITUTE(SUBSTITUTE(A1, "#", ""), "$", "")

2. Using the REPLACE Function

Similar to SUBSTITUTE, the REPLACE function allows you to replace characters in a text string but requires you to specify the position.

Example:

=REPLACE(A1, 1, 1, "")

This would replace the first character in A1 with an empty string, effectively removing it.

3. Using Array Formulas for Multiple Characters

If you need to remove a list of specific non-alphanumeric characters, you can use an array formula combined with the TEXTJOIN function.

Example:

Assuming you want to remove the characters !@#$%, you can use this formula:

=TEXTJOIN("", TRUE, IF(ISERROR(FIND(MID("!@#$%", ROW($1:$5), 1), A1)), MID(A1, ROW($1:$999), 1), ""))

Important Note: After typing this formula, press Ctrl + Shift + Enter to make it an array formula.

4. Using the CLEAN Function

The CLEAN function removes all non-printable characters from a text string. While this won’t eliminate all unwanted characters, it can be helpful if your data contains such characters.

Example:

=CLEAN(A1)

5. Combining Functions

Combining functions can be very powerful! You can use CLEAN and SUBSTITUTE together to cover all bases.

Example:

=SUBSTITUTE(CLEAN(A1), "#", "")

This would first remove non-printable characters and then remove the '#' character.

6. Using the FIND and REPLACE Tool

Excel's Find and Replace tool allows you to quickly locate and replace non-alphanumeric characters.

1. Press Ctrl + H to open the Find and Replace dialog.
2. Enter the character you want to remove in the "Find what" box.
3. Leave the "Replace with" box empty.
4. Click Replace All.

7. Leveraging Text to Columns

If you have characters separating your text (like commas or spaces), you can use the Text to Columns feature to split your data into multiple columns and then remove the unwanted characters.

1. Select the column containing your data.
2. Go to the Data tab and select Text to Columns.
3. Choose Delimited and click Next.
4. Select the delimiter (e.g., comma, space) and click Finish.

This will separate your data into different columns, allowing you to delete the unwanted parts easily.

8. Creating a Macro

If you're dealing with large datasets, creating a simple macro to automate the removal of non-alphanumeric characters can save you time.

Example VBA Code:

Sub RemoveNonAlphaNumeric()
    Dim cell As Range
    For Each cell In Selection
        cell.Value = WorksheetFunction.Text(cell.Value, "General")
    Next cell
End Sub

To use this macro, press Alt + F11 to open the VBA editor, insert a new module, and paste the code. You can then run it on your selected data range.

9. Using Power Query

For more complex transformations, Power Query in Excel can be extremely helpful.

1. Load your data into Power Query.
2. Select the column you want to clean.
3. Go to the Transform tab and choose Replace Values to remove specific characters.
4. Once done, click Close & Load to bring the clean data back into Excel.

10. Manual Review

Lastly, while it's not the most efficient method, a manual review can sometimes be necessary. Go through your cleaned data visually to ensure no unwanted characters remain. It’s also a chance to catch any errors that automated processes might have missed.

Common Mistakes to Avoid

1. Not Making a Backup: Always keep a copy of your original data before applying any clean-up methods.
2. Overcomplicating Formulas: Stick to straightforward solutions. More complex formulas can lead to confusion and errors.
3. Ignoring Non-Printable Characters: Remember to use the CLEAN function if your data contains non-printable characters.

Troubleshooting Tips

• If a function isn't working as expected, double-check the reference cell and ensure your syntax is correct.
• Use the Evaluate Formula tool in Excel to step through complex formulas and see where they might be failing.
