Catatan
Ini adalah salah satu rangkaian artikel yang memperincikan penyelesaian yang dihantar untuk cabaran Podcast 2316.
Dalam video asal saya mengenai pembentukan semula data, saya sampai di satu titik di mana saya perlu mendapatkan 2 watak pertama dari lajur. Kaedah saya melibatkan Split Column untuk menghasilkan 2 watak pertama dan semua yang lain. Saya kemudian memadamkan semua yang lain.
Mike Girvin dari saluran ExcelisFun, serta Brandon Brimberry, Wyn Hopkins dari Access Analytic, Geert Demulle menyatakan bahawa cara yang lebih pantas adalah menggunakan Transform, Extract, First Characters.
Ini menyimpan maklumat suku sahaja tanpa perlu menghapus bahagian lajur yang lain.
Bohdan Duda menggunakan Teks Ekstrak Sebelum Pembatas untuk mendapatkan semuanya sebelum watak _.
Mike Girvin menyatakan bahawa penyelesaiannya adalah "dengan cepat, sebelum saya keluar dari pintu." Inilah kodnya:
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 penyelesaian 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 cabaran Podcast 2316.
