work attendance

Hi giorgionway ,

If you mean extract the total hours based on 'in', 'out' fields, you can try to use the following query:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCknKzMkszlTSUXJPzS9KTwUyDI30DA30DC0VDA2sDAyQBYyMQAKxOsjaXBLLMlNQdBmi6zKE6XJKLCnNBWnyy8xLRFZiia7FANMiFPcZorvPkBj3GaK7z5Cw+wzR3GeI5L5YAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [City = _t, #"Worker Name" = _t, In = _t, Out = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"City", type text}, {"Worker Name", type text}, {"In", type datetime}, {"Out", type datetime}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Worker Name"}, {{"Contents", each Table.AddColumn(Table.AddColumn(_,"Date",each Date.From([Out])),"Hour",each Duration.TotalHours([Out]-[In])), type table}}),
    #"Expanded Contents" = Table.ExpandTableColumn(#"Grouped Rows", "Contents", {"Date", "Hour"}, {"Date", "Hour"}),
    #"Pivoted Column" = Table.Pivot(Table.TransformColumnTypes(#"Expanded Contents", {{"Date", type text}}, "en-US"), List.Distinct(Table.TransformColumnTypes(#"Expanded Contents", {{"Date", type text}}, "en-US")[Date]), "Date", "Hour", List.Sum)
in
    #"Pivoted Column"

If above not meet for your requirement, can you please explain more about the logic about transforming your date fields?
