    How to edit string

    kieran keene



      I am looking to remove everything to the left of the first '.'


      I have a list of domains:






      Each of the subdomains are different lengths.


      How would I do this?

          Hi Kieran,


          Find my approach as reference below and stored in attached workbook version 9.3

            Hi Kieran,


            What Norbert suggested sounds sufficient for this situation and a good approach.

            Two other options that may be useful in these situations are:


            1) Using regular expressions

            This depends slightly on how your fields are formatted. For the examples you named you could use a calculated field with the following expression:

            REGEXP_EXTRACT([F1], ".*\.(.*\.[Cc]om)")

            This approach is in some ways more flexible. However, this may not match all of your fields (for instance if it is not always '.com' you would have to change the expression.)


            2)  Using SPLIT

            Create a custom split in a calculated field, which uses the period to split the field, then define how you want to put the parts together. In this case you want to add the second and the third part and will have to add in the period between them again.

            SPLIT( [F1], '.', 2) + '.'+ SPLIT( [F1], '.', 3)

              H Naledi,


              Thanks for stepping in. What I like about Tableau you can start "simple" and end up "sophisticated". Thanks for that:)
