List Month end or end date between date ranges

Hi RK9009,

I think I have a solution for you problem:

 

Here the code in Power Query M that you can paste into the advanced editor (if you do not know, how to exactly do this, please check out this quick walkthrough)

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTIy1TfRNzIwArENTfXNIexYnWglI6CIqb4RTBKo0BQqGQsA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [StudentID = _t, #"Start Date" = _t, #"End Date" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"StudentID", Int64.Type}, {"Start Date", type date}, {"End Date", type date}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each { Number.From([Start Date])..Number.From([End Date]) }),
    #"Expanded Custom" = Table.ExpandListColumn(#"Added Custom", "Custom"),
    #"Changed Type1" = Table.TransformColumnTypes(#"Expanded Custom",{{"Custom", type date}}),
    #"Added Custom1" = Table.AddColumn(#"Changed Type1", "Custom.1", each Date.EndOfMonth([Custom])),
    #"Added Custom2" = Table.AddColumn(#"Added Custom1", "Custom.2", each if [Custom.1] = [Custom] or [End Date] = [Custom] then 1 else 0),
    #"Filtered Rows" = Table.SelectRows(#"Added Custom2", each ([Custom.2] = 1)),
    #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Custom.1", "Custom.2"})
in
    #"Removed Columns"

 

Hope this helps!
