How do you split a table of IDs and Concatenated Strings into a normalized table?

[jzy5282]

 Each concatString shows (Value, Year, Status, RowID)  with a pipe separator.  How to split and transpose so it shows 4 columns: RowID, Value, Year, Status?

Table Values [ID], [concatString]

839	0.00|2021|false|839|35,000.00|2022|true|839|35,000.00|2023|true|839|35,000.00|2024|true|839|35,000.00|2025|true|839|35,000.00|2026|true|839|0.00|2027|false|839|

Hi @jzy5282 ,

Split [concatString] column into list by the separator "|".
Split this list into smaller lists every 4.
Expand the list into rows and columns.

Please try the query.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("ddItE8IwDAbg/1K949Iu6TaJAIXiQ+0mEKBQfLj8eArXXrMsk+/TijdtxtH17eAaBxsADhA836+P142TcksNQDkI/H5+DG9XHFecVjxWL9SJLm5qUlWEX9V05pHPx8uOk/A/k8pR5U7lXuVhngPU7AOVt1laMKzl/fZwUogWkoVRYB7bL8b27NP1+ejComGdYb1hQ7X5U+TsVQ4q1/EzoAbSEAXkkUksJZRFQFIViBFA/YSwWkUgWkgWRoGLpUzmpukL", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ID = _t, concatString = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"concatString", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "SplitToLists", each List.Split( Splitter.SplitTextByDelimiter("|")([concatString]),4)),
    #"Expanded SplitToLists" = Table.ExpandListColumn(#"Added Custom", "SplitToLists"),
    #"Extracted Values" = Table.TransformColumns(#"Expanded SplitToLists", {"SplitToLists", each Text.Combine(List.Transform(_, Text.From), ";"), type text}),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Extracted Values", "SplitToLists", Splitter.SplitTextByDelimiter(";", QuoteStyle.Csv), {"Value", "Year", "Status", "RowID"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Value", Int64.Type}, {"Year", Int64.Type}, {"Status", type logical}, {"RowID", Int64.Type}})
in
    #"Changed Type1"

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.
