I recently attended a workshop with an expert panel where people provided their best Excel tips. One tip involved filtering cells with a certain number of words. A nice tip, but it left some attendees wondering how to count words in Excel. The program doesn’t have this feature, but this formula tutorial will show you how to count words in Excel. (Includes practice file.)

The summit tip was for a specific product, but opportunities exist where you might want to count words in an Excel cell. For example, I do a similar process when I pull a list of site search queries from my web analytics to see people’s interests.

## Spaces Can Impact Word Count

**The key to counting words in Excel is to identify the spaces between words correctly. **You need to remove leading and trailing spaces in the cells, or the word count will be inflated. There are a couple of ways to do this. A simple way is to use an Excel add-on such as ASAP Utilities.

Another way is to use the **Excel TRIM function**. The trim function removes leading and trailing spaces in a cell. This text function also removes extra spaces between words to just one space. In the screen snap below, you can see that the spaces aren’t always obvious. You have to compare the counts in Columns B and C.

In addition to TRIM, I’ll also use Excel’s LEN and **SUBSTITUTE **functions. These are also considered TEXT functions.

**LEN **returns the number of characters in a string. In my case, the number will reflect the number for each cell. Since a “space” is considered a character, it is counted.

**SUBSTITUTE **is similar to “search and replace” on a cell, except we can specify how many times the substitution should occur. For example, you could indicate once, all, or a specific number.

For example, the formula ** =SUBSTITUTE(A1,"firefox","google") would replace the word “firefox” with “google” for cell A1**.

For our purposes, we want to substitute a space “ “ with nothing. Effectively, the function removes all spaces, so the words run together. “Example text” would change to “Exampletext.”

## Understanding the Word Count Formula

One nice feature of Excel is that you can nest formulas that include multiple functions. The formula below references LEN, TRIM, and SUBSTITUTE. It also starts with the IF function, which we’ve outlined before.

To get the word count in cell A2 in my spreadsheet, I would use this formula in B2,

`=IF(LEN(TRIM(A2))=0,0,LEN(TRIM(A2))-LEN(SUBSTITUTE(A2," ",""))+1)`

While stringing Excel functions together is efficient, it may make the formula intimidating. You’ll note in the screen snap below and on the lesson spreadsheet, I’ve added more columns to make this clearer.

Let me break this down for you.

- We TRIM any extra spaces in cell A2 and determine if the cell is blank by using
`=IF(LEN(TRIM(A2))=0,0`

. If A2 is blank, it assigns the word count as 0. - If A2 isn’t blank, we count the characters in the cell using
`LEN(TRIM(A2))`

. You might think of this as our starting character count inclusive of spaces. - We use
`LEN(SUBSTITUTE(A2)," ","")`

to remove the remaining spaces. We then count the characters in this new string. - We take the LEN count from Step 2 and subtract the LEN count from Step 3. We then add one to the count to adjust for the first word.

In the above example, I placed the formula in Column B. However, you can also add more columns to show various stages. This often helps when learning a nested formula. In the screen snap below, my formula is in **Column F**.

## Presenting Another Way

If you prefer word problems, think of it this way. If the cell is empty, make the word count = 0. Otherwise, remove the extra spaces and count the characters in the cell. Hold that value as “A.” Now, remove all spaces in that cell and count the characters again. Hold that value as “B.” Your word count is (A-B) + 1.

“Sample example text” = LEN count of 19. This is your “A.”

“Sampleexampletext” = LEN count of 17. This is your “B.”

(19-17)+1 = word count of 3.

After writing this formula, I think I have a new appreciation for the ease at which some programs, like Microsoft Word, can return a word count. If you want to see an example with these formulas, you can download the sample Excel spreadsheet.

## One Step Further

Now that we have had Excel count words, we can filter that column for a minimum or maximum value. Another option might be to convert the spreadsheet into a table and then add an Excel slicer.
