Catatan
Ini adalah salah satu dari rangkaian artikel yang merinci solusi yang dikirim untuk tantangan Podcast 2316.
Dalam video asli saya tentang pembentukan ulang data, saya sampai pada titik di mana saya perlu mendapatkan 2 karakter pertama dari kolom. Metode saya melibatkan Split Column untuk menghasilkan 2 karakter pertama dan yang lainnya. Saya kemudian menghapus yang lainnya.
Mike Girvin dari saluran ExcelisFun, serta Brandon Brimberry, Wyn Hopkins dari Access Analytic, Geert Demulle mencatat bahwa cara yang lebih cepat adalah menggunakan Transformasi, Ekstrak, Karakter Pertama.
Ini hanya menyimpan informasi kuartal tanpa perlu menghapus sisa kolom.
Bohdan Duda menggunakan Ekstrak Teks Sebelum Pembatas untuk mendapatkan semua sebelum karakter _.
Mike Girvin mencatat bahwa solusinya adalah "dengan cepat, cepat sebelum saya keluar." Ini kodenya:
let Source = Excel.CurrentWorkbook()((Name="BadStartData"))(Content), #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(Source, ("Category Description"), "Quarter", "Amount"), #"Added Custom" = Table.AddColumn(#"Unpivoted Other Columns", "Employee", each if not Text.StartsWith((Quarter),"Q") then (Quarter) else null), #"Filled Down" = Table.FillDown(#"Added Custom",("Employee")), #"Extracted First Characters" = Table.TransformColumns(#"Filled Down", (("Quarter", each Text.Start(_, 2), type text))), #"Filtered Rows" = Table.SelectRows(#"Extracted First Characters", each Text.StartsWith((Quarter), "Q")), #"Pivoted Column" = Table.Pivot(#"Filtered Rows", List.Distinct(#"Filtered Rows"(Quarter)), "Quarter", "Amount", List.Sum), #"Filtered Rows1" = Table.SelectRows(#"Pivoted Column", each ((Employee) "Dept. Total")), #"Inserted Sum" = Table.AddColumn(#"Filtered Rows1", "Total", each List.Sum(((Q1), (Q2), (Q3), (Q4))), type number), #"Sorted Rows" = Table.Sort(#"Inserted Sum",(("Employee", Order.Ascending),("Category Description", Order.Ascending))), #"Changed Type" = Table.TransformColumnTypes(#"Sorted Rows",(("Q1", type number), ("Q2", type number), ("Q3", type number), ("Q4", type number), ("Total", type number), ("Employee", type text), ("Category Description", type text))) in #"Changed Type"Inilah solusi Geert DeMulle:
let Source = Excel.CurrentWorkbook()((Name="tblUglyData"))(Content), #"Changed Type" = Table.TransformColumnTypes(Source,(("Category Description", type text), ("Dept. Total", type number), ("Q1", type number), ("Q2", type number), ("Q3", type number), ("Q4", Int64.Type), ("Employee 1", type number), ("Q12", type number), ("Q23", type number), ("Q34", Int64.Type), ("Q45", Int64.Type), ("Employee 2", Int64.Type), ("Q16", Int64.Type), ("Q27", Int64.Type), ("Q38", Int64.Type), ("Q49", Int64.Type), ("Employee 3", Int64.Type), ("Q110", Int64.Type), ("Q211", Int64.Type), ("Q312", Int64.Type), ("Q413", Int64.Type), ("Employee 4", type number), ("Q114", type number), ("Q215", type number), ("Q316", type number), ("Q417", Int64.Type))), #"Removed Columns" = Table.RemoveColumns(#"Changed Type",("Dept. Total", "Q1", "Q2", "Q3", "Q4")), #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Removed Columns", ("Category Description"), "Attribute", "Value"), #"Added Conditional Column" = Table.AddColumn(#"Unpivoted Other Columns", "Employee", each if Text.StartsWith((Attribute), "Employee") then (Attribute) else null), #"Filled Down" = Table.FillDown(#"Added Conditional Column",("Employee")), #"Filtered Rows" = Table.SelectRows(#"Filled Down", each Text.StartsWith((Attribute), "Q")), #"Extracted First Characters" = Table.TransformColumns(#"Filtered Rows", (("Attribute", each Text.Start(_, 2), type text))), #"Renamed Columns" = Table.RenameColumns(#"Extracted First Characters",(("Attribute", "Quarter"))), #"Pivoted Column" = Table.Pivot(#"Renamed Columns", List.Distinct(#"Renamed Columns"(Quarter)), "Quarter", "Value"), #"Changed Type1" = Table.TransformColumnTypes(#"Pivoted Column",(("Employee", type text))), #"Inserted Sum" = Table.AddColumn(#"Changed Type1", "Total", each List.Sum(((Q1), (Q2), (Q3), (Q4))), type number), #"Sorted Rows" = Table.Sort(#"Inserted Sum",(("Employee", Order.Ascending), ("Category Description", Order.Ascending))) in #"Sorted Rows"Kembali ke halaman utama untuk tantangan Podcast 2316.
