Convert Whole Number to Time in Power Query

Hi tlotfi,

Here I made one sample for your reference.

Firstly, we need to split the column, then we can merge the columns we got as the picture below.

Here is the M code in power query for your reference.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjQ1MlGK1QExDMzADAMLI1Mww8jIyFgpNhYA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", Int64.Type}}),
    #"Split Column by Position" = Table.SplitColumn(Table.TransformColumnTypes(#"Changed Type", {{"Column1", type text}}, "en-US"), "Column1", Splitter.SplitTextByPositions({0, 2}, true), {"Column1.1", "Column1.2"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Position",{{"Column1.1", Int64.Type}, {"Column1.2", Int64.Type}}),
    #"Inserted Merged Column" = Table.AddColumn(#"Changed Type1", "Merged", each Text.Combine({Text.From([Column1.1], "en-US"), Text.From([Column1.2], "en-US")}, ":"), type text),
    #"Changed Type2" = Table.TransformColumnTypes(#"Inserted Merged Column",{{"Merged", type time}})
in
    #"Changed Type2"
