How to convert hours, minutes, second in PowerBI to minutes? - time

Question

Hi everyone,
I have a table named Table1 with a column showing Time Taken for student to finish the exam (as shown in the screenshot above). May I know how should I convert the column to minutes? Basically need to convert hrs (if exist) to minutes and convert sec to minute as well.
To simplify the output, if the sec more than or equal to 30sec, then counted as 1 min, otherwise just ignore the sec. I'm still new to PowerBI, any help will be greatly appreciated!

You can perform these below steps in your table to get your desired output-
Advance Query Editor code
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","")
else if Text.PositionOf([#"Time Taken - Copy.3"],"hrs") > 0 then Text.Replace([#"Time Taken - Copy.3"],"hrs","")
else "0"),
#"Added Custom1" = Table.AddColumn(#"Added Custom", "min", each if Text.PositionOf([#"Time Taken - Copy.1"],"min") > 0 then Text.Replace([#"Time Taken - Copy.1"],"min","")
else if Text.PositionOf([#"Time Taken - Copy.2"],"min") > 0 then Text.Replace([#"Time Taken - Copy.2"],"min","")
else if Text.PositionOf([#"Time Taken - Copy.3"],"min") > 0 then Text.Replace([#"Time Taken - Copy.3"],"min","")
else "0"),
#"Added Custom2" = Table.AddColumn(#"Added Custom1", "sec", each if Text.PositionOf([#"Time Taken - Copy.1"],"sec") > 0 then Text.Replace([#"Time Taken - Copy.1"],"sec","")
else if Text.PositionOf([#"Time Taken - Copy.2"],"sec") > 0 then Text.Replace([#"Time Taken - Copy.2"],"sec","")
else if Text.PositionOf([#"Time Taken - Copy.3"],"sec") > 0 then Text.Replace([#"Time Taken - Copy.3"],"sec","")
else "0"),
#"Removed Columns" = Table.RemoveColumns(#"Added Custom2",{"Time Taken - Copy.1", "Time Taken - Copy.2", "Time Taken - Copy.3"}),
#"Changed Type2" = Table.TransformColumnTypes(#"Removed Columns",{{"hrs", Int64.Type}, {"min", Int64.Type}, {"sec", Int64.Type}}),
#"Added Custom3" = Table.AddColumn(#"Changed Type2", "final_minutes", each ([hrs]*60) + [min] + (if [sec]>=30 then 1 else 0))
in
#"Added Custom3"
