Power BI中如何将小时、分钟、秒转换为分钟？

Question

大家好，

我有一个名为 Table1 的 table，其中有一列显示学生完成考试所用的时间（如上面的屏幕截图所示）。我可以知道如何将列转换为分钟吗？基本上需要将 hrs（如果存在）转换为分钟并将 sec 转换为分钟。

为简化输出，如果sec大于或等于30秒，则计为1分钟，否则忽略sec。我还是 PowerBI 的新手，非常感谢任何帮助！

您可以在 table 中执行以下步骤以获得所需的输出-

let
    //... your previous steps,
    // Change the PREVIOUS STEP NAME accordingly in the NEXT line


    #"Replaced Value1" = Table.ReplaceValue(#"PREVIOUS STEP NAME"," hrs","hrs",Replacer.ReplaceText,{"Time Taken"}),
    #"Replaced Value" = Table.ReplaceValue(#"Replaced Value1"," min","min",Replacer.ReplaceText,{"Time Taken"}),
    #"Replaced Value2" = Table.ReplaceValue(#"Replaced Value"," sec","sec",Replacer.ReplaceText,{"Time Taken"}),
    #"Duplicated Column" = Table.DuplicateColumn(#"Replaced Value2", "Time Taken", "Time Taken - Copy"),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Duplicated Column", "Time Taken - Copy", Splitter.SplitTextByDelimiter(" ", QuoteStyle.Csv), {"Time Taken - Copy.1", "Time Taken - Copy.2", "Time Taken - Copy.3"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Time Taken - Copy.1", type text}, {"Time Taken - Copy.2", type text}, {"Time Taken - Copy.3", type text}}),
    #"Replaced Value3" = Table.ReplaceValue(#"Changed Type1",null,"",Replacer.ReplaceValue,{"Time Taken - Copy.1", "Time Taken - Copy.2", "Time Taken - Copy.3"}),
    #"Added Custom" = Table.AddColumn(#"Replaced Value3", "hrs", each if Text.PositionOf([#"Time Taken - Copy.1"],"hrs") > 0 then Text.Replace([#"Time Taken - Copy.1"],"hrs","")
else if Text.PositionOf([#"Time Taken - Copy.2"],"hrs") > 0 then Text.Replace([#"Time Taken - Copy.2"],"hrs","")
