This works because when the number of characters ( num_chars) exceeds the remaining string length MID will extract all remaining text. Using LEN to provide num_chars is a simple way to give MID a number that is always large enough. LEN will return 30 in this case, but there are only 20 characters left to extract after the "//". This is actually a hack to keep things simple. Extract all domain names (e.g from URLs present as hyperlinks in a HTML text. The number of characters to extract is provided by the LEN function, which returns the number of characters in cell C5. To remove the protocol in a second step, you can use a formula like this: =MID(C5,FIND("//",C5)+2,LEN(C5))Įssentially, this formula uses the MID function and the FIND function to extract text starting after the "//". One limitation of this formula is that it leaves the protocol (i.e. To get the domain name without a trailing slash, we subtract 1 from the result of FIND like so: =LEFT(B5,FIND("/",B5,9)-1) The result is the domain name with a trailing slash, "". With the text "" in cell B5, the third instance of "/" is the 21st character in the URL, so FIND returns the number 21. The LEFT function then extracts 21 characters from the URL, starting at the left. URLs begin with something called a "protocol" which looks like this:īy starting at the 9th character, the protocol is skipped, and the FIND function will return the location of the third instance of "/", which is the first instance after the double slash in the protocol. This is the "clever" part of the formula. First, FIND locates the "/" character in the URL, starting at the 9th character: FIND("/",B5,9) For a quick solution, you can use a formula like this: =LEFT(B5,FIND("/",B5,9)-1)Īt the core, this formula is extracting characters from the left side of the URL with the LEFT function, and using the FIND function to figure out how many characters to extract. In older versions of Excel without the TEXTBEFORE or TEXTAFTER functions, this is a more challenging problem. TEXTBEFORE locates the single forward slash "/" and returns all previous text. Here, TEXTBEFORE is configured to use a single forward slash "/" for the delimiter. This text is then handed off directly to the TEXTBEFORE function as the text argument for further processing: =TEXTBEFORE("/formulas/","/") With the text "" in cell B5, TEXTAFTER returns "/formulas/". TEXTAFTER locates the double forward slash "//" and returns all text that follows. In this case, the protocol is the text " or " To locate the protocol, we use "//" for the delimiter and provide B5 for text: TEXTAFTER(B5,"//") Working from the inside out, the TEXTAFTER function is first used to strip the "protocol" from the URL. This is an example of nesting one function inside another. In the worksheet shown, the formula in cell C5 uses both functions like this: =TEXTBEFORE(TEXTAFTER(B5,"//"),"/") delimiter - the place at which to split the text How can I fetch a domain name from a URL String Examples: +-+-+ input output +-+-+ google mail.To solve this problem, each function needs just two arguments, text and delimiter: =TEXTAFTER(text,delimiter) As the names imply, the TEXTAFTER function extracts text that occurs after a given delimiter, and the TEXTBEFORE function extracts text that occurs before a given delimiter. The formula in the worksheet shown uses the TEXTAFTER and TEXTBEFORE functions to extract domain names from URLs. In the current version of Excel, the easiest way to do this is to use a formula based on the TEXTAFTER and TEXTBEFORE functions. In older versions of Excel, you can use a more complicated formula based on the LEFT and FIND functions. = Text.Lower(List.RemoveMatchingItems(Text.Split(Text.Replace(,"://","."),".In this example, the goal is to extract the domain name from a list of URLs. Solution - Following formula can be used to extract domain from a given URL Hence, which has subdomain powerbi.microsoft is excluded. Below are some sample cases and the results expected.Įxclusion - Subdomains are excluded from the scope of this. Use Case - Sometimes there will be a need to extract domain names from given URLs.
