Hi, community,
I'm facing a problem to unstack this copied & pasted info in a column and make it into a table.
I found the rows of info sets are not consistent (some have 4 rows, some 5 rows) and not able to use Mordulo function. So I tried to add another column and identify the "null" row with index "0" and would like to fill the consequence number then Pivot table, then everything should be fine. But do not know how to fill down the numbers. 😥
Please let me know whether my toughts are correct and could work. If so, how to finish the rest steps. If not, please suggest if any other good solutions.
Thank you.
PS: Sorry that I can not enclose this data file as with confidentiality problem.

Hi @lcy0328
Place the following M code in a blank query to see the steps:
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WUorViVbyMYRQRhDKGEKZQChTMAVVB1MIpY2htIkhiiK4KrgyuDo0hQiVCKUItVCWKZgVCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Col1 = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Col1", type text}}),
#"Replaced Value" = Table.ReplaceValue(#"Changed Type","",null,Replacer.ReplaceValue,{"Col1"}),
list0_ = #"Replaced Value"[Col1],
list1_ = if List.Last(list0_)<>null then list0_&{null} else list0_ = null, //Make sure list finishes with a null to make things easier in the next step
list2_ = if List.First(list1_)=null then List.LastN(list1_,List.Count(list1_)-1) else list1_,
list3_ = List.Accumulate(list2_,[total={}, partial={}],(s,c)=> if c<>null then [total=s[total], partial=s[partial]&{c}] else [total=s[total]&{s[partial]}, partial={}]),
total = list3_[total],
#"Converted to Table" = Table.FromList(total, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
#"Added Custom" = Table.AddColumn(#"Converted to Table", "Custom", each Text.Combine([Column1],"|")),
#"Split Column by Delimiter" = Table.SplitColumn(#"Added Custom", "Custom", Splitter.SplitTextByDelimiter("|", QuoteStyle.Csv), {"Line1", "Line2", "Line3", "Line4", "Line5"}),
#"Removed Columns" = Table.RemoveColumns(#"Split Column by Delimiter",{"Column1"})
in
#"Removed Columns"

Hello @lcy0328
try this approach. Uses Table.Group to split your tables on every "null", then skip and transpose every single column.
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WUorViVbyMYRQRhDKGEKZQChTMAVVB1MIpY2htIkhiiK4KrgyuDo0hQiVCKUItVCWKZgVCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Col1 = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Col1", type text}}),
#"Replaced Value" = Table.ReplaceValue(#"Changed Type","",null,Replacer.ReplaceValue,{"Col1"}),
#"Grouped Rows" = Table.Group(#"Replaced Value", {"Col1"}, {{"AllRows", each Table.Transpose(Table.Skip(_,1)), type table [Col1=text]}}, GroupKind.Local, (g,c)=> if c[Col1]=null then 1 else 0),
#"Removed Other Columns" = Table.SelectColumns(#"Grouped Rows",{"AllRows"}),
#"Expanded AllRows" = Table.ExpandTableColumn(#"Removed Other Columns", "AllRows", {"Column1","Column2","Column3","Column4","Column5"})
in
#"Expanded AllRows"

@lcy0328 try put this code in the step next to the Source.
=Table.Comine(Table.Group(Source,"Column1",{"n",each Table.FromRows({List.Skip([Column1])})},0,(x,y)=>Byte.From(y=null))[n])
