    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8k1MzsjMS1XSUXJJLAFR/qUlBaUlSrE6cDkFQ6CwgaGegamekYGRKZBjZIApb4Qkb4xF3hhJ3tAUU94MWT8WeXMkeRMs8hZI8mZA+2MB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"(blank)" = _t, #"(blank).1" = _t, #"(blank).2" = _t]),
    #"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]),
    #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"Date", type date}}),
    Date = List.Skip( #"Changed Type"[Date],1),
    Custom1 = Date,
    Custom2 = List.InsertRange( Custom1,List.Count(Custom1),{null}),
    Custom3 = Table.ToColumns(#"Changed Type")&{Custom2},
    #"Converted to Table" = Table.FromList(Custom3, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Extracted Values" = Table.TransformColumns(#"Converted to Table", {"Column1", each Text.Combine(List.Transform(_, Text.From), "|"), type text}),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Extracted Values", "Column1", Splitter.SplitTextByDelimiter("|", QuoteStyle.Csv), {"Column1.1", "Column1.2", "Column1.3", "Column1.4", "Column1.5", "Column1.6"}),
    #"Transposed Table" = Table.Transpose(#"Split Column by Delimiter"),
    #"Added Index" = Table.AddIndexColumn(#"Transposed Table", "Index", 1, 1, Int64.Type),
    #"Inserted Date Subtraction" = Table.AddColumn(#"Added Index", "Subtraction", each if Duration.Days(Date.From([Column4]) - Date.From([Column2]))=1 then null else [Index]),
    #"Filled Up" = Table.FillUp(#"Inserted Date Subtraction",{"Subtraction"}),
    #"Grouped Rows" = Table.Group(#"Filled Up", {"Subtraction"}, {{"Count", each _, type table [Column1=text, Column2=text, Column3=text, Column4=nullable text, Index=number, Subtraction=number]}, {"MinDate", each List.Min([Column2]), type text}, {"MaxDate", each List.Max([Column2]), type text}}),
    #"Expanded Count" = Table.ExpandTableColumn(#"Grouped Rows", "Count", {"Column1", "Column2", "Column3", "Column4", "Index"}, {"Column1", "Column2", "Column3", "Column4", "Index"}),
    #"Removed Columns" = Table.RemoveColumns(#"Expanded Count",{"Subtraction", "Column4", "Index"})
    in
    #"Removed Columns"
