Creating a hierarchy from indented column
I have the following table:
It has a column that contains levels of indentation signifying a hierarchical relationship. I'd like to ask how this could be unwrapped into the following table please?
Perhaps this should be sorted out with the help of Python script? All help and tips are appreciated.
Thank you!

Try this.
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcgQCpVidaCUFJyCAsBScDUEAynE0AgEYxxgEIBxnICBaQywA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Block = _t]), #"Added Index" = Table.AddIndexColumn(Source, "Index", 0, 1), #"Added Custom" = Table.AddColumn(#"Added Index", "Level", each "Block Level " & Number.ToText( List.Count( List.Accumulate( Text.ToList( [Block] ), {" "}, ( s,a ) => if a = List.Last(s) then s & {a} else s ) ) - 1 ) ), #"Trimmed Text" = Table.TransformColumns(#"Added Custom",{{"Block", Text.Trim, type text}}), #"Pivoted Column" = Table.Pivot(#"Trimmed Text", List.Distinct(#"Trimmed Text"[Level]), "Level", "Block"), #"Filled Down" = Table.FillDown(#"Pivoted Column",{"Block Level 0", "Block Level 1"}), #"Filtered Rows" = Table.SelectRows(#"Filled Down", each ([Block Level 2] <> null)) in #"Filtered Rows"Best Regards,

Apologies Mariusz , perhaps my example problem was too generic. I have updated my question to reflect the true scenario which i have where I believe your specific solution might not work.
