In computer programming and text processing, removing characters from the beginning or end of a text string is often necessary. It can be useful when dealing with user input, file paths, or any other text data that needs to be formatted or manipulated. There are several ways to delete characters from the beginning or end of a text string, depending on your programming language or platform. Some common methods include string slicing, regular expressions, built-in string manipulation functions, or even simple loops. In this article, we will explore some of the most common techniques used to delete characters from the beginning or end of a text string in various methods. These methods can efficiently process large amounts of text data and ensure it is properly formatted for your applications.
Microsoft Excel provides plenty of shortcuts to do different kinds of tasks on it. We can also use the built-in functions and formulas to perform mathematical operations. In Excel, we can add some additional plug-ins like Kutools to simplify and simplify our work.

In Excel, you can use different formulas, functions and Kutools to delete characters from the beginning or end of a text string. Here are some examples:
Removing characters from the beginning of a string
- Step 1 – To remove characters from the beginning of a string in Excel, you can use the RIGHT function.
- Step 2 – The RIGHT function returns a specified number of characters from the end of a text string. By providing a negative value as the function’s second argument, you can remove characters from the beginning of a string.
- Step 3 – For example, to remove the first three characters of a string in cell A1, you can use the following formula:
=RIGHT(A1, LEN(A1)-3)
- Step 4 – This formula returns all the characters in the string except the first three characters.
Removing characters from the end of a string
- Step 1 – You can use the LEFT function to remove characters from the end of a string in Excel.
- Step 2 – The LEFT function returns a specified number of characters from the beginning of a text string. By providing a negative value as the function’s second argument, you can remove characters from the end of a string.
- Step 3 – For example, to remove the last three characters of a string in cell A1, you can use the following formula:
=LEFT(A1, LEN(A1)-3)
- Step 4 – This formula returns all the characters in the string except the last three characters.
Removing Characters from the beginning of the Text String with Kutools
If you want to remove certain numbers of characters from the beginning or left of the text string, follow the below steps.
- Step 1 – First, you must select the range you want to remove certain characters.
- Step 2 – Go to the Kutools Tab, select the Text option, and choose the Remove by Position option from the menu.
- Step 3 – Then, it will open the Remove by position Dialog Box.
- Numbers – In this box, you must specify the number of characters to remove.
- Position – Here, you need to check the From left option.
- Step 4 – Then, click the OK button.
- Step 5 – You can see that the specified number of characters has been removed from the range of text strings, as shown in the image below.
Deleting Characters from the End of the Text String with Kutools
You can also delete a certain number of characters from the end of the text string, as follows.
- Step 1 – Firstly, you must select the range you want to remove certain characters.
- Step 2 – On the Kutools Tab, select the Text option, and choose the Remove by Position option from the menu.
- Step 3 – Then, it will open the Remove by position Dialog Box.
- Numbers – In this box, you must specify the number of characters to remove.
- Position – Here, you need to check the From right option.
- Step 4 – Then, click the OK button.
- Step 5 – The specified characters have been deleted from the right of the text strings, as shown in the image below.
Remove a Certain number of Characters from a Specified Position of the Text String
With this utility, you can remove a certain number of characters from a specified position of a text string. To do this, follow the below steps.
- Step 1 – You need to select the range that you want to remove certain characters.
- Step 2 – Go to the Kutools Tab, select the Text option, and choose the Remove by Position option from the menu.
- Step 3 – Then, it will open the Remove by position Dialog Box.
- Numbers – In this box, you must specify the number of characters to remove.
- Position – Here, you must check the Specify option and select the character position using the given drop-down list.
- Step 4 – Then, click the OK button.
- Step 5 – At last, you can see that the characters you specified have been removed from the text strings. Refer to the below image.
