Excel TRIM function - quick way to remove extra spaces

The tutorial demonstrates a few quick and easy ways to trim Excel spaces. Learn how to remove leading, trailing, and extra spaces between words, why Excel TRIM function is not working and how to fix it.

Are you comparing two columns for duplicates that you know are there, but your formulas cannot find a single duplicate entry? Or, are you adding up two columns of numbers, but keep getting only zeros? And why on earth does your obviously correct Vlookup formula return just a bunch of N/A errors? These are only a few examples of problems that you may be seeking answers to. And all are caused by extra spaces hiding before, after or between numeric and text values in your cells.

Microsoft Excel offers a few different ways to remove spaces and clean up your data. In this tutorial, we will investigate the capabilities of the TRIM function as the fastest and easiest way to delete spaces in Excel.

TRIM function - remove extra spaces in Excel

You use the TRIM function in Excel removes extra spaces from text. It deletes all leading, trailing and in-between spaces except for single space characters between words.

The syntax of the TRIM function is the easiest one could imagine:

Where text is a cell that you want to remove excess spaces from.

For example, to remove spaces in cell A1, you use this formula:

=TRIM(A1)

And the following screenshot shows the result:

Yep, it's that simple!

If in addition to extra spaces, your data contains line breaks and non-printing characters, use the TRIM function is combination with CLEAN to delete the first 32 non-printing characters in the in the 7-bit ASCII code system.

For example, to remove spaces, line breaks and other unwanted characters from cell A1, use this formula:

=TRIM(CLEAN(A1))

How to use TRIM function in Excel - formula examples

Now that you know the basics, let's discuss a few specific uses of TRIM in Excel, pitfalls that you may face and working solutions.

How to trim spaces in an entire column of data

Supposing you have a column of names that have some whitespace before and after the text, as well as more than one spaces between the words. So, how do you remove all leading, trailing and excess in-between spaces in all cells at a time? By copying a n Excel TRIM formula across the column, and then replacing formulas with their values. The detailed steps follow below.

1. Write a TRIM formula for the topmost cell, A2 in our example:

   =TRIM(A2)

2. Position the cursor to the lower right corner of the formula cell (B2 in this example), and as soon as the cursor turns into the plus sign, double-click it to copy the formula down the column, up to the last cell with data. As the result, you will have 2 columns - original names with spaces and formula-driven trimmed names.
   
3. Finally, replace the values in the original column with the trimmed data. But be careful! Simply copying the trimmed column over the original column would destroy your formulas. To prevent this from happening, you need to copy only values, not formulas. Here's how:
   • Select all cells with Trim formulas (B2:B8 in this example), and press Ctrl+C to copy them.
   • Select all cells with the original data (A2:A8), and press Ctrl+Alt+V, then V. It is the paste values shortcut that applies the Paste Special > Values
   • Press the Enter key. Done!

How to remove leading spaces in a numeric column

As you have just seen, the Excel TRIM function removed all extra spaces from a column of text data without a hitch. But what if your data is numbers, not text?

At first sight, it may seem that the TRIM function has done its job. Upon a closer look, however, you will notice that the trimmed values do not behave like numbers. Here are just a few indications of abnormality:

• Both the original column with leading spaces and trimmed numbers are left-aligned even if you apply the Number format to the cells, while normal numbers are right-aligned by default.
• When two or more cells with trimmed numbers are selected, Excel displays only COUNT in the status bar. For numbers, it should also display SUM and AVERAGE.
• A SUM formula applied to the trimmed cells returns zero.

From all appearances, the trimmed values are text strings, while we want numbers. To fix this, you can multiply the trimmed values by 1 (to multiply all the values in one fell swoop, use the Paste Special > Multiply option).

A more elegant solution is enclosing the TRIM function in VALUE, like this:

=VALUE(TRIM(A2))

The above formula removes all leading and trailing spaces, if any, and turns the resulting value into a number, as shown in the screenshot below:

How to remove only leading spaces in Excel (Left Trim)

In some situations, you may type duplicated and even triplicated spaces between words to make your data better readable. However, you do want to get rid of leading spaces, like this:

As you already know, the TRIM function eliminates extra spaces in the middle of text strings, which is not what we want. To keep all in-between spaces intact, we'll be using a bit more complex formula:

=MID(A2,FIND(MID(TRIM(A2),1,1),A2),LEN(A2))

In the above formula, you the combination of FIND, MID and TRIM calculates the position of the first text character in a string. And then, you supply that number to another MID function so that it returns the entire text sting (the string length is calculated by LEN) starting at the position of the first text character.

The following screenshot shows that all leading spaces are gone, while multiple spaces between words are still there:

As a finishing touch, replace the original text with the trimmed values, as shown in step 3 of the Trim formula example, and you are good to go!

How to count extra spaces in a cell

Sometimes, before removing spaces in your Excel sheet, you may want to know how many excess spaces are actually there.

To get the number of extra spaces in a cell, find out the total text length using the LEN function, then calculate the string length without extra spaces, and subtract the latter from the former:

=LEN(A2)-LEN(TRIM(A2))

The following screenshot shows the above formula in action:

How to highlight cells with excess spaces

When working with sensitive or important information, you may be hesitant to delete anything without seeing what exactly you are deleting. In this case, you can highlight cells containing extra spaces first, and then safely eliminate those spaces.

For this, create a conditional formatting rule with the following formula:

=LEN($A2)>LEN(TRIM($A2))

Where A2 is the topmost cell with data that you want to highlight.

The formula instructs Excel to highlight cells in which the total string length is greater than the length of the trimmed text.

To create a conditional formatting rule, select all the cells (rows) that you want to highlight without column headers, go to the Home tab > Styles group, and click Conditional formatting > New Rule > Use a formula to determine which cells to format.

If you are not familiar with Excel conditional formatting yet, you will find the detailed steps here: How to create a conditional formatting rule based on formula.

As demonstrated in the screenshot below, the result perfectly corroborates with the extra spaces count that we got in the previous example:

As you see, the use of the TRIM function in Excel is easy and straightforward. Nevertheless, if someone wants to have a closer look at the formulas discussed in this tutorial, you are welcome to download the Trim Excel Spaces Workbook.

Excel TRIM not working

The TRIM function is designed to remove only the space character, represented by code value 32 in the 7-bit ASCII character set. In the Unicode character set, there is one more space character called the non-breaking space, which is commonly used on web pages as the html character  . The nonbreaking space has a decimal value of 160, and the TRIM function cannot remove it by itself.

So, if your dataset contains one or more white spaces that the TRIM function does not remove, use the SUBSTITUTE function to convert non-breaking spaces into regular spaces and then trim them. Assuming the text is in A1, the formula goes as follows:

=TRIM(SUBSTITUTE(A1, CHAR(160), " "))

The following screenshot shows the difference:

If the above formula does not work for you either, chances are that your data contain some specific nonprinting characters with code values other than 32 and 160. In this case, use one of the following formulas to find out the character code, where A1 is a problematic cell:

Leading space: =CODE(LEFT(A1,1))

Trailing space: =CODE(RIGHT(A1,1))

In-between space (where n is the position of the problematic character in the text string):

=CODE(MID(A1, n, 1)))

And then, supply the returned character code to the TRIM(SUBSTITUTE()) formula discussed above.

For example, if the CODE function returns 9, which is the Horizontal Tab character, you use the following formula to remove it:

=TRIM(SUBSTITUTE(A1, CHAR(9), " "))
