How to Change to Sentence Case in Excel [Formula]


In Excel, we have three specific functions to convert text from one case to another.

Whereas there is another case for which we don’t have any function...

...or any other option.

That’s ==> Sentence Case

You might be wondering: What sentence case actually is?

Well, in sentence case, for an entire sentence, the first letter of the first word should be in the capital case and rest of the letters of the first word and all the other words should be in lower case.

Something like this:

sentence case in excel is differ from other cases


Convert to Sentence Case in Excel

To create a formula for sentence case we need to use five different text functions. Let's your text is in cell A1, then the formula will be:


How it works

To understand this formula, we need to split it into two parts.

In the first part, the left function returns the first character of and then upper function converts it into upper case.

In the second part, will convert rest of the text to lower case as we need rest of the letters in lower case for sentence case.

And finally, this combination return the text in sentence case.

Yes, that's it.

Convert to Sentence Case for More than One Sentence

The formula we have learned above is simple and easy to apply. But, do you have the same thought in your mind which I have right now?

What will we do if there is more that one sentence in a cell?

This is crazy:

And you know, in this situation above formula is for nothing, we can't use it.

We do need a different formula which can convert a text into the sentence case when we have more than one sentence.

Here's the formula:

=SUBSTITUTE(SUBSTITUTE(PROPER(SUBSTITUTE(SUBSTITUTE(LOWER(C12),". ","9z9")," ","zxz")),"9Z9",". "),"zxz"," ")

How it works

So you want to learn how this formula works? Right? Well, you need to hold your nerves and stay with me for a minute.

We need to split this formula into three different parts like I have done below.

In the first part, with lower function and two substitute functions, we have converted the text into lower case and replace all the spaces within words with “zxz” and space and dot between two sentences with “9z9”.

At this point, we don't have any space in our text. So far so good.

In the second part, we have converted the entire text into the proper case using the proper function.

secret you need to learn

Whenever you convert a text into a proper case and you have a number in that text, the function will treat that text separate words. Look at the below example.

In the third part, we have again used two substitute functions to replace “zxz” with a space and “9z9” with a dot and space.

In this way, we have converted our multiple sentence text into an actual sentence case text.

Sometimes we use Excel to type some sort of text and there is probability to type it in the wrong case.

And, if you know to convert a text into sentence case, you can correct your text easily.

If you have a sentence where you have a question mark instead of a dot then you can use the question mark in the formula and rest of the formula will be same.

I hope this formula tip will help you in your work.

Now, tell me one thing.

Do you have any other method to do this text conversion?

  1. This is where your blog is unique. you give practical stuff never heard of elsewhere and provide a lucid explanation with example files.

    Though nothing too advanced which is excel guru level but useful stuff that others wouldnt have thought of

  2. Puneet, nice formula.

    Problem is that it does not play well with punctuation and other non-alphabet characters (eg , . ] 🙂

    Example “yes please” correctly returns “Yes please” but “yes, please” returns “Yes,Zxzplease”

    It can be corrected with a further SUBSTITUTE(“Zxz”,” “) in the formula

    Paul :Zxz)

    • Paul, can you restate the entire formula with the added substitute to fix the comma problem? I really need the formula to work with commas in sentences, and I can’t figure out how/where to add the extra substitute you suggested. Additionally, can we add another substitute to get the formula to handle apostrophes? If yes, what would that formula look like?

  3. Good explanation and nice formula Puneet. Please check ASAP utilities Addin for Excel (free for non commercial use) in the option Text (collection of tools number 2 to 7) specially 7th item. Many options and works on many including filtered cells and saves lot of time. No need to use functions or formulas by the user.
