Formula to pick out certain words in an url field

[Maria]

Hi I have been looking for ages but just can’t work out what I need to put. I have a url field and want to create a formula to be able to group records from where they came from say ‘airtable.com’ or ‘youtube’ as a ‘live’ way to group. So easy with filters - wish you could use ‘contain’ in formulas i would be laughing!

Thanks, Maria

You could try using this to isolate just the root URL:

LEFT(
   SUBSTITUTE(
      SUBSTITUTE(
         {URL cell},
         "http://",
         ""
         ),
      "https://",
      ""
      ),
   FIND(
      "/",
      SUBSTITUTE(
         SUBSTITUTE(
            {URL cell},
            "http://",
            ""
         ),
      "https://",
      ""
      )
   )
   -1
)

This removes http(s)://, then looks for the first forward slash (ie, the end of the root domain name), and deletes anything after that.

With a URL like:
https://airtable.com/tblgM0vNFik7bg5P1/viwnGc4ETRwTXk68u?blocks=hide
this formula would return airtable.com.

With a URL like:
https://www.youtube.com/watch?v=4VR861BWkiU
this formula would return youtube.com.

With a URL like:
https://community.airtable.com/t/formula-to-pick-out-certain-words-in-an-url-field/27430
this formula would return community.airtable.com.
