How Do I Stop 255 Character Limit in Excel (4 Ways)

During the many calculations phase, we encounter that text in cell formulas needs to be under 255 characters, which is annoying. In most cases, we have no option to shorten the text at all. If you are curious to know how you can stop the 255-character limit in Excel, then this article may come in handy for you. In this article, we discuss how you, I, or anyone else stop the 255-character limit in Excel with detailed explanations.

Stop 255 Character Limit in Excel: 4 Easy Ways

For the demonstration purpose, we used two separate long texts which can show errors when we used them directly. We presented four ways in which you can resolve the issue.

1. Using CONCATENATE Function

We can use the CONCATENATE function, we can join two long texts (over 255 characters) altogether without any warning sign.


  • If we need to use a formula that involves a character length greater than 255, we will face a warning like the one shown below.
  • Because Excel put a restriction of 255 lengths on the character length in Excel.
  • The warning box states that you need to use the CONCATENATE function or the Ampersand operator.
  • Click OK after this.

  • Let us append the text below altogether.
  • Now, we will separate the text into two separate parts, and then we will add them together using the CONCATENATE function.
  • The key here is to separate the text into almost equal parts in cells C4 and in C5.

Using CONCATENATE Function to Stop 255 Character Limit in Excel

  • Select cell C7 and enter the following formula:


  • Doing this will append both parts of the text altogether.
  • And this time there is no warning sign to be seen.

  • And this is how you, I, or anyone else can stop the 255-character limit in Excel using the CONCATENATE function.

2. Using Ampersand Operator

We are using the Ampersand sign to join two long texts of over 255 characters placed in two separate cells.


  • Similar to the CONCATENATE function, we can easily add different parts altogether using the &(Ampersand) sign.
  • But if we tried to add text longer than 255 characters directly in the formula bar, then there would be an error.
  • And this error clearly instructs us to opt for the CONCATENATE function or the & sign in between text.

  • To do this, we need to separate the texts into two different parts.
  • Then, we will use the cell location of the texts to add them together.

Using Ampersand Operator to Stop 255 Character Limit in Excel

  • Select cell C7 and enter the following formula


  • Entering this formula will add the text in two cells altogether in cell C7.

  • After entering the formula, you will notice that cell C7 now has the appended part of the text in cells C4 and C5.
  • And now it’s not showing any warning signs right now.

  • And this is how you, I, or anyone else can stop the 255-character limit in Excel using the Ampersand sign.

3. Save Your Excel File as XLSX Format

XLSX files actually store data in compressed B format.  In an XLS file, data is stored as binary streams in a compound file, as explained in [MS-XLS]. An XLSX file, on the other hand, is based on the Office Open XML format, which stores data in ZIP files that are made up of compressed XML files. If you unzip the.xlsx file, you can determine the structure and files underneath. The XLS file has some limitations compared to the XLSX version. XLS normally doesn’t have the capability of showing over 255 characters. XLSX does have the capability of showing strings having over 255 characters.

So, if your cell contains more than 255 characters and your Excel file format is XLS, try switching to XLSX. This may resolve the issue.

4. Modifying Registry Editor

Registry Editor is a visual operator that allows users to modify the configuration settings of various programs. Altering those settings can enable us to avoid the issue of the 255 character limit in Excel efficiently.


  • If your imported data in Excel is being truncated below 255 characters automatically, then the below procedure can help you avoid it.
  • In the beginning, type Registry Edit in the search box.

  • After pressing enter, you will be taken to the following location.
  • In that location, double-click on the TypeGuessRows.

  • And put 0 in the Value data.
  • Click OK after this.


  • After clicking OK, the issue should be resolved.

      Greetings Gin Got,
      Sorry for the issue that you are facing. Unfortunately, the issue of 255 characters in a single cell is a fundamental feature in the Excel environment. But on the other hand, the character limit in a formula is infinite. So I suggest you stick to this article’s first or second method.
      Now coming to the 4th method in which you are not getting so much success, is that this method is only for Users of Excel 2007-Excel 2013 in a very specific area. Users who are getting trouble importing data to the Myssql server are experiencing this issue of getting characters truncated in the cell. This 4th method is the solution for that reason. The article will now be updated with a note with this disclaimer. If you need further assistance then please feel free to contact us again, attaching necessary files is recommended.

      Thanks and Regads
