Hi,

This M code works

let
    Source = Excel.CurrentWorkbook(){[Name="Data"]}[Content],
    #"Added Custom" = Table.AddColumn(Source, "Duration", each 1*([endDate]-[StartDate])),
    #"Changed Type" = Table.TransformColumnTypes(#"Added Custom",{{"Duration", Int64.Type}}),
    #"Added Custom1" = Table.AddColumn(#"Changed Type", "Custom", each {1..[Duration]}),
    #"Expanded Custom" = Table.ExpandListColumn(#"Added Custom1", "Custom"),
    #"Removed Columns" = Table.RemoveColumns(#"Expanded Custom",{"Duration"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Removed Columns",{{"StartDate", type date}, {"endDate", type date}})
in
    #"Changed Type1"

Hope this helps.

Ashish_Mathur  Thanks this worked for me with but with an integer range use case. It was a small look up table that eventually results in 20.000 exploded rows, so not a very huge table. Performance is ok.
