Year interval

Hi Leo64 ,

If you want to implement it in Power Query Editor, please refer to the following command.

let
  Source = Table.FromRows(
    Json.Document(
      Binary.Decompress(
        Binary.FromText("i45WMjIwMtAFEiZKsTpgnimIZwnlGYPkjIFysQA=", BinaryEncoding.Base64), 
        Compression.Deflate
      )
    ), 
    let
      _t = ((type nullable text) meta [Serialized.Text = true])
    in
      type table [Year = _t]
  ), 
  #"Changed Type" = Table.TransformColumnTypes(Source, {{"Year", type text}}), 
  #"Inserted Text Before Delimiter" = Table.AddColumn(
    #"Changed Type", 
    "Text Before Delimiter", 
    each Text.BeforeDelimiter([Year], "-"), 
    type text
  ), 
  #"Inserted Text After Delimiter" = Table.AddColumn(
    #"Inserted Text Before Delimiter", 
    "Text After Delimiter", 
    each Text.AfterDelimiter([Year], "-"), 
    type text
  ), 
  #"Renamed Columns" = Table.RenameColumns(
    #"Inserted Text After Delimiter", 
    {{"Text Before Delimiter", "StartYear"}, {"Text After Delimiter", "EndYear"}}
  ), 
  #"Changed Type1" = Table.TransformColumnTypes(
    #"Renamed Columns", 
    {{"StartYear", Int64.Type}, {"EndYear", Int64.Type}}
  ), 
  #"Added Custom" = Table.AddColumn(#"Changed Type1", "Custom", each [EndYear] - [StartYear]), 
  #"Changed Type2" = Table.TransformColumnTypes(#"Added Custom", {{"Custom", Int64.Type}}), 
  #"Added Custom1" = Table.AddColumn(
    #"Changed Type2", 
    "Custom.1", 
    each List.Numbers([StartYear], [Custom] + 1, 1)
  ), 
  #"Expanded Custom.1" = Table.ExpandListColumn(#"Added Custom1", "Custom.1"), 
  #"Removed Columns" = Table.RemoveColumns(
    #"Expanded Custom.1", 
    {"Year", "StartYear", "EndYear", "Custom"}
  )
in
  #"Removed Columns"

Attached PBIX file for reference, you can observe each step in APPLIED STEPS on the right.
