The TRIM function is fully automatic. It removes removes both leading and trailing spaces from text, and also "normalizes" multiple spaces between words to one space character only. All you need to do is supply a reference to a cell.
TRIM with CLEAN
If you also need to remove line breaks from cells, you can add the CLEAN function like so:
The CLEAN function removes a range of non-printing characters, including line breaks, and returns "cleaned" text. The TRIM function then takes over to remove extra spaces and returns the final text.
Other problematic characters
Note that CLEAN is not able to remove all non-printing characters, notably a non-breaking space, which can be appear in Excel as CHAR(160). By adding the SUBSTITUTE function to the formula, you can remove specific characters. For example, to remove a non-breaking space, you can use:
The formula runs from the inside out, with each SUBSTITUTE removing one character. The inner most SUBSTITUTE removes the left parentheses, and the result is handed to the next SUBSTITUTE, which removes the right parentheses, and so on. Whenever you...
The SUBSTITUTE function can find and replace text in a cell, wherever it occurs. In this case, we are using SUBSTITUTE to find a character with code number 202, and replace it with an empty string (""), which effectively removes the character...
The Excel SUBSTITUTE function replaces text in a given string by matching. For example =SUBSTITUTE("952-455-7865","-","") returns "9524557865"; the dash is stripped. SUBSTITUTE is case-sensitive and does not support wildcards.
