How to Remove Special Characters in Excel [7 Methods]

When working with data imported from different sources or generated through user input, we may encounter special characters that can complicate our analysis or presentation. Symbols, punctuation marks, non-printable characters, and other characters not found in the regular alphanumeric set are examples of special characters. Removing these special characters from the data is essential to ensure data consistency. In this article, I will show you 7 different techniques to remove special characters in Excel.

1. Using the Flash Fill Method to Remove Special Characters in Excel

Flash Fill is a powerful data manipulation tool in Microsoft Excel. It is the easiest way to remove the special characters in Excel. However, the Flash Fill feature is available only in Microsoft Excel 2013 and later versions.

Let’s say we have a Dataset with a few special characters, as seen in the image below. Let’s remove them by utilizing the Flash Fill feature.

Note: If we do not have sequentially special characters like “#%$” or if the special characters are placed randomly in every data, then we have to remove them one by one, using the Find and Replace tool multiple times.

3. Removing Special Characters with the SUBSTITUTE Function

Another way to remove the special character is by using a SUBSTITUTE function. It is used to replace a character with another.





Formula Breakdown

  • The inner SUBSTITUTE function takes the text from cell C9 and replaces all occurrences of “#” with an empty string. It effectively removes all pound symbols from the text in cell C9.
  • The outer SUBSTITUTE function takes the result of the inner SUBSTITUTE function (i.e., the text with “#” removed) and further replaces all occurrences of”! ” with an empty string. It removes all exclamation marks from the text obtained after the inner replacement.
  • This Nested SUBSTITUTE function is used to sequentially remove special characters from a text string, first removing “#” and then removing“! “. If there are more special characters we can use more substitute functions.

Excel’s SUBSTITUTE function makes it simple to eliminate special characters. The steps are listed below:

  1. Copy the formula above.
  2. Apply the formula in cell D2.Remove Special Character using Substitute function
  3. Drag the Fill Handle from D2 to D10.Substitute function drag down process

Final Result 

As a result, all special characters from every cell have been removed.

4. Remove Special Characters in Excel Using Replace Function

Any character from any cell can be replaced using the REPLACE function. The methods below will show you how to replace special characters in Excel using the REPLACE function.


= REPLACE(old_text, start_num, num_chars, new_text)



Formula Breakdown

This formula in Excel is used to modify the contents of cell C2.

  • It replaces a specified number of characters in the cell with a new string or blanks.
  • In this specific case, starting from the fourth character in the cell content, one character is replaced with an empty string (“”).
  • The parameters for the REPLACE function are defined as follows: the reference cell is C2, the starting position for replacement is the fourth character, the number of characters to replace is one, and the replacement string is an empty string.

This formula is often employed when you want to eliminate or replace specific characters within a text string in Excel.

If you want to remove special characters in Excel, you can use the REPLACE function. Here’s how:

  1. Copy the formula above.
  2. Apply the formula in cell D2.Replace Function Formula to remove special character
  3. Drag the Fill Handle from D2 to D10.dragging down Replace Function to remove special character in Excel

Final Result

As a result, all special characters from every cell have been removed by using REPLACE Function.

5. Remove Special Characters by Using Reduce Function

One of Excel 365’s flexible functions is REDUCE. It can be applied to conditional sum, count, maximum, and minimum calculations.

It is a LAMBDA helper function that applies a LAMBDA to each element of an array or range to convert it to an accumulated value.


=REDUCE([initial_value], array, lambda(accumulator, value))


= REDUCE(C2:C10,Sp_Char[Character to Remove],LAMBDA(x,spchar,SUBSTITUTE(x,spchar,"")))

Formula Breakdown

  • This formula utilizes the REDUCE function to iteratively apply a LAMBDA function to a range (C2:C10).
  • The LAMBDA function takes two parameters, ‘x’ representing each cell value and ‘spchar’ representing a character specified in the named range ‘Sp_Char[Character to Remove]’.
  • Within the LAMBDA, SUBSTITUTE is used to replace occurrences of the specified character with an empty string.
  • The REDUCE function then accumulates these modified values, effectively removing the specified characters from the range.

This formula is particularly useful for bulk character removal within a range in Excel.

Excel’s REDUCE function can be used to remove special characters. Here’s how to do it:

  1. Go to Insert.
  2. Select Table or press CTRL+T to create “Table” for Character to Remove.Creating table for Reduce Function
  3. Insert values of the Table.Reduce function character to remove table
  4. Rename the Table to Sp_char.Reduce function table naming process
  5. Copy the formula above.
  6. Apply the formula in cell D2.Reduce function formula to remove special characters in Excel

Final Result

Press the ENTER button and all special characters from the range D2:D10 will be removed by using the REDUCE Function.

6. Remove Special Characters in Excel Using Power Query

Power Query is a data transformation and cleaning tool in Excel that allows you to manipulate data from various sources. Power Query can be used to delete special characters from Excel if you are using Microsoft Excel 2016 or Excel 365. You can download it from the Microsoft website if you are using Microsoft Excel 2010 or 2013.

Custom Column Formula


Formula Breakdown

It is likely used in Power Query or Power BI.

  • It selects and retains only alphanumeric characters from the ‘Password’ column.
  • The expression within curly braces represents a range of characters, ensuring that both uppercase and lowercase letters (A to z) along with numeric digits (0 to 9) are included.

This helps filter and preserve only alphanumeric characters in the specified column, aiding data cleaning or transformation processes.

Here’s how you can remove special characters using Power Query:

  1. Select C1:C10 with a header.
  2. Go to Data and Select From Table/Range.Power query table range selection
  3. Then a Create Table message will appear and tick the My Table Has Header option.
  4. After that click OK.Power query table naming

    Set targetRange = Application.InputBox("Select a range to remove special characters:", Type:=8)
    On Error GoTo 0
    If targetRange Is Nothing Then
         MsgBox "No range selected. Operation canceled."
         Exit Sub
    End If
    Application.ScreenUpdating = False
    ' Loop through each cell in the selected range
    For Each cell In targetRange
         cellValue = cell.Value
         cleanedValue = ""
         ' Loop through each character in the cell value
         For charIndex = 1 To Len(cellValue)
             specialChar = Mid(cellValue, charIndex, 1)
             ' Check if the character is not in the list of special characters
             If InStr(1, specialChars, specialChar, vbBinaryCompare) = 0 Then
                 cleanedValue = cleanedValue & specialChar
             End If
         Next charIndex
         ' Update the cell value with the cleaned value
         cell.Value = cleanedValue
    Next cell
    Application.ScreenUpdating = True
