TRIM function does not remove the nonbreaking spaces represented by CHAR(160), which can be done by using the SUBSTITUTE function as shown below. Length of returned string is 15 characters. TRIM Function deletes one space between "James" and "Bond". Refer Image 1a.įormula returns the string "James Bond 007". The string Length - LEN(A1) - is 16 characters. Note that there are 2 spaces between " James" and "Bond" and then 2 spaces (nonbreaking space characters with decimal value of 160) between "Bond" and "007". To remove the higher value Unicode characters, the SUBSTITUTE function is used.Ĭell A1 contains the string: = "James"&CHAR(32)&CHAR(32)&"Bond"&CHAR(160)&CHAR(160)&"007". By themselves both these functions do not remove the higher value Unicode characters - the TRIM function does not remove the nonbreaking space character (value 160) and the CLEAN function does not remove the additional non-printing characters (values 127, 129, 141, 143, 144, and 157). The CLEAN function was meant to remove the first 32 non-printing characters in the 7 bit ASCII code (values 0 to 31). The TRIM function was meant to remove the 7-bit ASCII space character (value 32). If you copy data into Excel from a web page, the non-breaking spaces that are generally used in web pages may also show up in your worksheet. A text may contain: space characters - Unicode character set value 32 which is a 7-bit ASCII space character non-breaking space characters - Unicode character set value 160 generally used in web pages with html name non-printing characters - Unicode character set values 0 to 31 which are the first 32 non-printing characters in the 7 bit ASCII code additional non-printing characters - Unicode character set values 127, 129, 141, 143, 144, and 157.

You often work with text received from other applications which might have irregular spacing or contain characters which might not print with your operating system, and in these cases it is apt to use the TRIM & CLEAN functions. Though most times a simple formula " =TRIM(CLEAN(A1))" can remove spaces and nonprinting characters from text, but the two functions of TRIM & CLEAN are not always fully effective in removing some characters for which an alternate method is required. Use a combination of the TRIM, CLEAN and SUBSTITUTE functions Syntax: CLEAN(text).Ĭell A1 contains: =CHAR(17)&"James"&CHAR(17)&"Bond"ĬLEAN Function removes the nonprintable characters, CHAR(17) from the string, and returns "JamesBond". Note that Trim removes the first 32 non-printing characters in the 7 bit ASCII code (values 0 to 31), but does not remove the additional non-printing characters with values 127, 129, 141, 143, 144, and 157 in the Unicode character set. The excel CLEAN Function is used to remove all nonprintable characters from text. TRIM leaves single space between words and removes leading, trailing & multiple inbetween spaces from text. Note that Trim removes the space character with ANSI code 32, but does not remove the non-breaking space character in the Unicode character set with decimal value 160 which is used extensively in web pages (with html entity  ). Trim deletes all leading & trailing spaces in a text string, and multiple spaces within words are reduced to a single space.

Use the excel TRIM function to remove all spaces from text leaving only single spaces between words. Leading and trailing blank characters will result in incorrect sorting & filtering of your data extra spaces and characters will prevent correct working of your formulas (say, when you do a vlookup), cause formatting & calculation errors, and generally impede in manipulating text/data besides appearing visibly incorrect. To remove the extra / unwanted spaces and non-printable characters from the data, use the Excel TRIM & CLEAN functions. When you import data into an Excel worksheet, or download from internet, or copy from a website, or in case of multiple users working on the same worksheet, you might often find unnecessary spaces or irregular characters, at times invisible, which were not intended to be part of the actual data. Excel Text and String Functions: LEFT, RIGHT, MID, LEN, FIND, SEARCH, REPLACE, SUBSTITUTE. ASCII Code, Extended ASCII characters (8-bit system) and ANSI Code.ģ.
