How to remove non-printable characters in Excel?

In this lesson, you will learn how to remove non-printable characters in Excel with the clean and substitute functions.

It may happen that data copied from external websites will be pasted with non-printable characters. This lesson lets you clean up your spreadsheet. You can't print such characters. It looks really unprofessional.

How to identify if cleaning is needed

The formula will indicate if cleaning is required for your cell.

How to remove non printable characters

To remove non-printable characters, use the CLEAN function. Syntax is:

=CLEAN(text)

You remove non-printable characters. You can also use the address of a cell phone. The syntax in that condition is:

=CLEAN(A1) for a single cell.

or

=CLEAN(A1:B10) for the whole range of cells

How to substitute non printable characters

If you know which nonprinting character you want to remove, you can do so with the Substitute function.

The Substitute function is used to replace characters. In this case, you're going to replace a specific nonprinting character with nothing. So you're just going to remove this mark.

Have yourself a specific identifier for the character you want to remove. Make it CHAR123.

Create a substitute formula like this: =SUBSTITUTE(A1,CHAR(123), "")

Using this substitute formula will remove CHAR123 from cell A1.
