    Hi FJS 

    This error indicates that you are trying to convert a text type value into Number type. This usually happens in the Changed type step. Please check whether the value "FC0001" appears in "PCI" column. If so, change its column type to text instead. 

     

    Change below step from

     

    #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"PCI", Int64.Type}, {"PCI Name", type text}, {"PCI Name_1", type text}, {"SiteIn", type text}, {"SiteIn_2", type text}}),

     

    to

     

    #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"PCI", type text}, {"PCI Name", type text}, {"PCI Name_1", type text}, {"SiteIn", type text}, {"SiteIn_2", type text}}),

    Thanks for the reply.

     

     

     

    If it is possible can you show me in other ways.

     

     

     

    It would be best if you can show in the way which have no coding in it.

     

    As my client might also need to do this in future by himself.

      Hi FJS 

       

      You can paste the code provided by m_dekorte into a blank query's Advanced Editor, click OK. Then you will see the result table. In the Applied Steps pane on the right side, there are detailed steps of this query. Click every step from top to bottom to check how it works step by step. 

       

      For a deep dive on how to incorporate M code from the forums into your code, you can refer to the following resources:

      Utilizing M Code Samples Given as Solutions in Power Query

      Power BI Forum Help: How to integrate M-code into your existing solution

       

      Don't be afraid of the M code. You will find that copying and pasting the M code is easier than replicating all steps one by one manually. And M code can be saved as a backup. 

       

      Feel free to let us know if you're not sure how a step is implemented.

       

      Best Regards,
      Jing

        Hi Anonymous m_dekorte ,

         

        I tried pasting code in my file but it is giving me error. IT looks like i have the number in the name column.

         

        Below is the code and snippet of the error.

        Error snippet

         

         

        Code:

        let

        Source = Excel.CurrentWorkbook(){[Name="Table7"]}[Content],
        #"Removed Columns" = Table.RemoveColumns(Source,{"Column4", "Column5", "Column6", "Column7", "Column10", "Column11", "Column12", "Column13", "Column14"}),
        #"Reordered Columns" = Table.ReorderColumns(#"Removed Columns",{"Column1", "Column2", "Column8", "Column3", "Column9"}),
        #"Removed Top Rows" = Table.Skip(#"Reordered Columns",1),
        #"Promoted Headers" = Table.PromoteHeaders(#"Removed Top Rows", [PromoteAllScalars=true]),

        UnpivotOthers = Table.UnpivotOtherColumns(#"Renamed Columns", {"PCI"}, "Attribute", "Value"),
        SplitByDelimiter = Table.SplitColumn(UnpivotOthers, "Attribute", Splitter.SplitTextByEachDelimiter({" "}, QuoteStyle.Csv, false), {"Attribute.1", "Attribute.2"}),
