The CLEAN Function removes all non-printable characters from text.
Use CLEAN on text imported from other applications that contains characters that may not print with your operating system. For example, you can use CLEAN to remove some low-level computer code that is frequently at the beginning and end of data files and cannot be printed.
Text Required. Any worksheet information from which you want to remove non-printable characters.
The CLEAN function was designed to remove the first 32 non-printing characters in the 7-bit ASCII code (values 0 through 31) from text. In the Unicode character set, there are additional non-printing characters (values 127, 129, 141, 143, 144, and 157). By itself, the CLEAN function does not remove these additional non-printing characters.
CLEAN function can not remove spaces from text, if you want to remove spaces, please use TRIM function.
The example may be easier to understand if you copy A1:C5 to a blank worksheet.
