Märge
See on üks artiklite seeria, mis kirjeldab üksikasjalikult Podcast 2316 väljakutsele saadetud lahendusi.
Andmete ümberkujundamise algses videos jõudsin punkti, kus mul oli vaja veerust kaks esimest märki hankida. Minu meetod hõlmas jagatud veergu, et genereerida esimesed 2 tähemärki ja kõik muu. Kustutasin siis kõik muu.
Mike Girvin kanalilt ExcelisFun, samuti Brandon Brimberry, Access Analyticust pärit Wyn Hopkins, Geert Demulle märkisid, et kiirem viis oleks kasutada teoseid Transform, Extract, First Characters.
See hoiab ainult veeranditeavet, ilma et oleks vaja ülejäänud veergu kustutada.
Bohdan Duda kasutas eraldatud teksti enne eraldajat, et saada kõik enne tähemärki _.
Mike Girvin märkis, et tema lahendus oli "lennult kiire, enne kui ma uksest väljas olen". Siin on tema kood:
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.
