How to get the top level domain (tld) from URL in Excel

In this article, we will learn How to get the top level domain(tld) from URL in Excel.

Scenario :

First we want to understand what a top level domain is. If given any URL or email address, sometimes we need to extract the last part after . (char) of the given url or email. That last part is called top level domain. In the snapshot shown below a general type of url is given and the top level domain of the url is com. The http part is called protocol, then its subdomain, then domain and last is the top level domain separated by . (char).

Below you will find more explanation about how to get a top level domain from any url or email address.

How to solve the problem?

Generally, the top level domain is found after the last . (char). For this problem, we will be using the following function.

  1. RIGHT function
  2. FIND function
  3. SUBSTITUTE function
  4. LEN function

Here we are going to use some logic to find the last .(char). RIGHT function extracts the text from the last knowing the number of characters to pick from last. That can be known if we differentiate the last . (char) from the rest . (char). The differentiating character must be a unique character. Then we will find the position of the differentiating character to get the start position of the top level domain.

Generic formula:

=RIGHT (url, LEN(url) - FIND("%", SUBSTITUTE (url,".","%", LEN(url) - LEN ( SUBSTITUTE(url,".","")))))

url : given url or email address

% : differentiating character

. : lookup char


Example :

All of this might be confusing to understand. Let's understand this example via running it on an example. Here we have some urls and we need to extract to last value which will be the top level domain. Below is the formula to get the 

Use the formula :

=RIGHT (C4, LEN(C4) - FIND("%", SUBSTITUTE (C4, "." , "%" , LEN(C4) - LEN ( SUBSTITUTE(C4,".","")))))


  • LEN ( SUBSTITUTE(C4, "." , "") returns the length of text in C4 without . (char).
  • LEN(C4) returns the length of the string.
  • The difference between the two will return the number of . (Char) in the text. Here we have 2 . (char), the formula drops down to.

= RIGHT( C4, 21 - FIND( "%" , SUBSTITUTE ( C4 , "." , "%" , 21-19 ) ) )

  • SUBSTITUTE function replaces the . (char) with "%" (differentiating character) only at the 2nd occurrence. The formula drops down to.

= RIGHT(C4,LEN (C4)-FIND("%",""))

  • FIND function now finds the "%" (char) in string and returns its position.
  • RIGHT function receives the num_char to return which is 3 from the right of the string.

Here all the arguments to the formula given using the cell reference. Press Enter to get the result.

As you can see in the above snapshot, the top level domain for the "" is com. Now Copy the formula to the rest of cells using the shortcut Ctrl + D or dragging down the right bottom corner of the B2 cell.

Here we can see that all the url or email address given to us, the formula extracts top level domain from all the values. Generally, we also receive the path value with url to get the 

Here are all the observational notes regarding using the formula.


  1. The formula only works with numbers.
  2. The differentiating character must be a unique character or else the formula returns error.
  3. Check the parts of the formula, first select the part and use F9. This is used to do if you want to check how your formula is working and clearing out some mistakes.
