How to split Azure resource tags in to separate columns.

Hi All, After much research and trial and error I am trying to figure out a way to parse the Azure resource tags that are exported using the Azure Enterprise connector and use them against other m...

Hi v-ljerr-msft

Sorry for the multiple posts but I think I have had some success. The code below which includes an IF statement at the start does seem to do the trick and doesn't error out when it can not find the key word. It may not be pretty but it seems to do the job, if you could offer any further refinements that would be great but otherwise I think we might have cracked it.

Hostname = 
IF(SEARCH( "Hostname" ,'Table1-Full'[Tags],,BLANK() ) ,(
VAR textLength =
    SEARCH (
        ",",
        'Table1-Full'[Tags],
        SEARCH ( "Hostname", 'Table1-Full'[Tags] ) + LEN ( "Hostname" )
            + 3
    )
        - (
            SEARCH ( "Hostname", 'Table1-Full'[Tags] ) + LEN ( "Hostname" )
                + 3
        )
        - 1
RETURN
    MID (
        'Table1-Full'[Tags],
        SEARCH ( "Hostname", 'Table1-Full'[Tags] ) + LEN ( "Hostname" )
            + 3,
        textLength
    )))

Thanks

Hi v-ljerr-msft

Thank you for your help with developing this solution. I have updated the code slightly to cater for the fact that when a particular Tag I am searching for is at the end of the text string the code would fail because it can't find the last delimitated character ",". So I have changed the delimited character to be ". Now any tag of any length and position within the string can be found and separated out into its own column. e.g. Workload, Location, Hostname. Hopefully this code can be used by others who are trying to report against Azure resource tags.

Hostname = IF(SEARCH( "Hostname" ,'All-Azure-Data'[Data.Tags],,BLANK() ) ,( VAR textLength = SEARCH ( """", 'All-Azure-Data'[Data.Tags], SEARCH ( "Hostname", 'All-Azure-Data'[Data.Tags] ) + LEN ( "Hostname" ) + 3 ) - ( SEARCH ( "Hostname", 'All-Azure-Data'[Data.Tags] ) + LEN ( "Hostname" ) + 3 ) RETURN MID ( 'All-Azure-Data'[Data.Tags], SEARCH ( "Hostname", 'All-Azure-Data'[Data.Tags] ) + LEN ( "Hostname" ) + 3, textLength )))

Hi v-ljerr-msft

Thank you for the code block. When I copy it across and update the table names it doesn't strictly work straight away. For reasons which I am not quite sure about any FIND command I use in Power BI desktop (which is the current April 2017 version) doesn't work unless I include ,,BLANK() on the end otherwise I get the error "The search Text provided to the function 'FIND' could not be found in the given text' so I have amended the code as per below. So it appears that all the FIND commands work now but the MID command does not.

I am presented with the error 'An argument of function 'MID' has the wrong data type or has an invalid value' so I am assuming this is because we are trying to pass it the variable name 'textLength' as the command works when I replace that with a number typed in by myself, my understanding was you couldn't pass a variable to the MID command. I'm sure the code block works when you constructed your example so I am not sure what the difference between the two could be, do you think I changed how the code executed by adding ,, BLANK() to the end of the FIND command.

Hostname = 
VAR textLength =
    FIND (
        ",",
        TestBatch4[Tags],
        FIND ( "Hostname", TestBatch4[Tags],,BLANK()) + LEN ( "Hostname" )
            + 3
    ,BLANK())
        - (
            FIND ( "Hostname", TestBatch4[Tags],,BLANK()) + LEN ( "Hostname" )
                + 3
        )
        - 1
RETURN
    MID (
        TestBatch4[Tags],
        FIND ( "Hostname", TestBatch4[Tags],,BLANK()) + LEN ( "Hostname" )
            + 3,
        textLength
    )

Once again thank you very much for your help and I certainly do like how this solution is being solved.

Regards

Hi v-ljerr-msft

After a bit more trial and error I have discovered the reason why the original code block doesn't work for me. I have noticed in my data set that I have rows which don't contain the key word hostname and thus the code returns the error 'FIND' could not be found in the given text'. As soon as I have a data set which contains 'Hostname' on every row the code works. I certainly appreciate your help so far so is it possible to wrap up the Find/Search commands with an IFERROR command so it skips over the rows that don't contain the key word. A sample dataset is below, apologies once again for not being to up front with the lay out of the entire data I have only just started out with Power BI.

{"WorkOrder":"6743","Hostname":"Srv04","Project":"1234AB","Location":"Sydney","Workload":"TestApp1"}

{"Hostname":"TestMgmt01","Location":"Sydney","Project":"8015JF","Workload":"TestApp2","Workorder":"7732"}

{"Hostname":"TestNPR01","Location":"Sydney","Project":"1234AA","Workload":"TestApp3","Workorder":"3315"}

{"WorkOrder":"6743","Hostname":"TestSvr02","Project":"1234AB","Location":"Sydney","Workload":"TestApp4"}

{"Hostname":"TestMgmt02","Location":"Sydney","Project":"4455CC","Workload":"TestApp2","Workorder":"7735"}

{"Hostname":"TestMgmt01","Location":"Sydney","Project":"8994TT","Workload":"TestApp2","Workorder":"7732"}

{"WorkOrder":"4467"}

{"Location":"Sydney"}

Thanks
