Shift Values to the Left for certain rows

Hi All,

 

I pulled out some data from a PDF and as expected not all data are well presented. My issues is that I have sometimes blank columns and all the data moved to the right. I need to get some data shifted to the left, I have tried unpivot but did not work for me

 

Here is the screenshot

 

 

let
    Source = Pdf.Tables(File.Contents("C:\XXXX\XXXX\XXXX\Storage 12.12.22 - 289775.pdf"), [Implementation="1.3"]),
    #"Lignes filtrées" = Table.SelectRows(Source, each ([Kind] = "Page")),
    #"Data développé" = Table.ExpandTableColumn(#"Lignes filtrées", "Data", {"Column1", "Column2", "Column3", "Column4", "Column5", "Column6", "Column7", "Column8", "Column9", "Column10", "Column11"}, {"Data.Column1", "Data.Column2", "Data.Column3", "Data.Column4", "Data.Column5", "Data.Column6", "Data.Column7", "Data.Column8", "Data.Column9", "Data.Column10", "Data.Column11"}),
    #"Colonnes supprimées" = Table.RemoveColumns(#"Data développé",{"Id", "Name", "Kind", "Data.Column1"}),
    #"Lignes filtrées1" = Table.SelectRows(#"Colonnes supprimées", each ([Data.Column2] <> null and [Data.Column2] <> "Card Payments :" and [Data.Column2] <> "M3 7BB" and [Data.Column2] <> "Part No" and [Data.Column2] <> "SALFORD")),
    #"Colonnes supprimées2" = Table.RemoveColumns(#"Lignes filtrées1",{"Data.Column4", "Data.Column5"})
in
    #"Colonnes supprimées2"

Here is my M code

    Hi Einomi ,

     

    Suppose we have:

    You may consider creating three new conditional columns. like this:

    = if [Data.Column6] = null then [Data.Column7] else [Data.Column6]
    = if [Data.Column6] = null then [Data.Column8] else [Data.Column7]
    = if [Data.Column6] = null then null else [Data.Column8]

    Then remove and rename the columns.

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTICYmOlWJ1oJQQnFgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Data.Column6 = _t, Data.Column7 = _t, Data.Column8 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Data.Column6", Int64.Type}, {"Data.Column7", Int64.Type}, {"Data.Column8", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each if [Data.Column6] = null 
then [Data.Column7] else [Data.Column6]),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Custom.1", each if [Data.Column6] = null 
then [Data.Column8] else [Data.Column7]),
    #"Added Custom2" = Table.AddColumn(#"Added Custom1", "Custom.2", each if [Data.Column6] = null 
then null else [Data.Column8]),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom2",{"Data.Column6", "Data.Column7", "Data.Column8"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Custom", "Data.Column6"}, {"Custom.1", "Data.Column7"}, {"Custom.2", "Data.Column8"}})
in
    #"Renamed Columns"

      Thanks Gao 🙂 

      Anonymousit works good. I had to shift 6 or 7 columns but the logic works 🙂
