Syntax of the CLEAN function
The CLEAN function in Excel follows a simple syntax: =CLEAN(text).
The “text” argument is where you specify the text you want to clean, either by directly entering the text or by providing a reference to the cell containing the text. It is important to note that the CLEAN function only accepts a single text argument, so if you want to clean multiple cells, you’ll need to apply the function to each individual cell or use other functions like CONCATENATE or TEXTJOIN to combine the values.
Here is an example of the CLEAN function syntax:
=CLEAN(A2)
In this case, A2 is the reference to the cell containing the text to be cleaned. You can replace “A2” with the appropriate cell reference for your data.
It is worth mentioning that the CLEAN function does not modify the original text. Instead, it returns a cleaned version of the text as the function’s result. So, if you want to replace the original text with the cleaned version, you need to copy and paste the cleaned values over the original ones.
Additionally, if the text contains printable characters only, the CLEAN function will return the original text without any changes.
It is worth noting some limitations of the CLEAN function. Firstly, the CLEAN function only removes characters with ASCII codes 0-31, which are considered non-printable characters. It will not remove other special characters or symbols that fall outside this range.
Secondly, the CLEAN function cannot remove characters that are not recognized as Unicode characters. If you have such characters in your text, they will not be affected by the CLEAN function.
