Simplify this steps

[Anonymous]

Hi, I have to use 6 column to create 3 date column that I can use later. This is done with multiple steps one column t the time.

How can I simplyfy this? Is there any tips?

#"Promoted Headers" = Table.PromoteHeaders(#"Emner - Detaljert oversikt - Em_Sheet", [PromoteAllScalars=true]),
#"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"Undervis. årstall", Int64.Type}}),
#"Replaced Value" = Table.ReplaceValue(#"Changed Type","HØST","8",Replacer.ReplaceText,{"Undervis. termin"}),
#"Replaced Value1" = Table.ReplaceValue(#"Replaced Value","VÅR","1",Replacer.ReplaceText,{"Undervis. termin"}),
#"Changed Type1" = Table.TransformColumnTypes(#"Replaced Value1",{{"Eksamen årstall", Int64.Type}, {"Undervis. termin", Int64.Type}}),
#"Replaced Value2" = Table.ReplaceValue(#"Changed Type1","HØST","8",Replacer.ReplaceText,{"Eksamen termin"}),
#"Replaced Value3" = Table.ReplaceValue(#"Replaced Value2","VÅR","1",Replacer.ReplaceText,{"Eksamen termin"}),
#"Changed Type2" = Table.TransformColumnTypes(#"Replaced Value3",{{"Eksamen termin", Int64.Type}, {"Kull årstall", Int64.Type}}),
#"Replaced Value4" = Table.ReplaceValue(#"Changed Type2","HØST","8",Replacer.ReplaceText,{"Kull termin"}),
#"Replaced Value5" = Table.ReplaceValue(#"Replaced Value4","VÅR","1",Replacer.ReplaceText,{"Kull termin"}),
#"Changed Type3" = Table.TransformColumnTypes(#"Replaced Value5",{{"Kull termin", Int64.Type}}),
#"Added Custom" = Table.AddColumn(#"Changed Type3", "Und_Dato", each Date.ToText(#date([Undervis. årstall], [Undervis. termin], 1))),
#"Changed Type4" = Table.TransformColumnTypes(#"Added Custom",{{"Und_Dato", type date}}),
#"Added Custom1" = Table.AddColumn(#"Changed Type4", "Eksamen_Dato", each Date.ToText(#date([Eksamen årstall], [Eksamen termin],1))),
#"Changed Type5" = Table.TransformColumnTypes(#"Added Custom1",{{"Eksamen_Dato", type date}}),
#"Added Custom2" = Table.AddColumn(#"Changed Type5", "Kull_Dato", each Date.ToText(#date([Eksamen årstall], [Eksamen termin], 1)))
in
#"Added Custom2"

Your Kull_dato formula was wrong.
