Altering data into different table layout

[primolee]

Hello everyone,

Currently I have this data source:

I want to alter it into the following:

Is there a way to achieve this in Power Query?  If not, is it possible in BI using DAX?

Thank you.

Hi @primolee ,

We can create a custom column in power query editor and expand it to rows to meet your requiremnet:

List.Dates([WeekStart],Duration.Days([WeekEnd]-[WeekStart])+1,#duration(1,0,0,0))

All the queries are here:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjIwtNQ31TdU0oExTYHMEDOlWB24pBlC0tAIJGuqFBsLAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [WeekStart = _t, WeekEnd = _t, #"week name" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"WeekStart", type date}, {"WeekEnd", type date}, {"week name", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Date", each List.Dates([WeekStart],Duration.Days([WeekEnd]-[WeekStart])+1,#duration(1,0,0,0))),
    #"Expanded Date" = Table.ExpandListColumn(#"Added Custom", "Date")
in
    #"Expanded Date"

Hi @primolee  

please check out the function that I've written for it here: https://www.thebiccountant.com/2017/12/11/date-datesbetween-retrieve-dates-between-2-dates-power-bi-...

Hello both,

Thank you so much, both of you!

Both are the solutions to my question, it is super difficult for me to decide whose answer to accept.

Dong's solution is very simple, whereas ImkeF's solution gives more flexibility of display by different interval.

I will accept ImkeF's reply as solution, but again, both work perfectly.

Thank you both for taking the time to help, greatly appreciated!
