split columns with null result
Hi yokaso ,
Thanks for Omid_Motamedise reply.
Based on the code you provided, it seems that you want to split the TRANSACT columns to get to the point where all the data has dates and values, if so, you can try the following code
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjTQByIjAyNjJR2l/LxUIAlkxupEK0H4SUAKzDU01AciqMKS8nyQQhOYQiAfodBIH4hgCjOKUsFmmsKVgkQgimMB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, Transact = _t, Value = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Transact", type text}, {"Value", Int64.Type}}),
FillDown = Table.FillDown(Table.AddIndexColumn(#"Changed Type", "Index", 1, 1, Int64.Type), {"Date"}),
FilteredRows = Table.SelectRows(FillDown, each ([Date] <> null)),
GroupedRows = Table.Group(FilteredRows, {"Date"}, {{"AllData", each _, type table [Date=nullable date, Transact=nullable text, Value=nullable number, Index=Int64.Type]}}),
AddCustom = Table.AddColumn(GroupedRows, "Custom", each let
TransactList = [AllData][Transact],
Transact1 = if List.Count(TransactList) > 0 then TransactList{0} else null,
Transact2 = if List.Count(TransactList) > 1 then TransactList{1} else null
in
[Transact1=Transact1, Transact2=Transact2]),
ExpandCustom = Table.ExpandRecordColumn(Table.ExpandTableColumn(AddCustom, "AllData", {"Value"}, {"Value"}), "Custom", {"Transact1", "Transact2"}),
RemoveNulls = Table.SelectRows(ExpandCustom, each [Value] <> null),
#"Renamed Columns" = Table.RenameColumns(RemoveNulls,{{"Transact1", "Transact"}, {"Transact2", "Transactb"}})
in
#"Renamed Columns"Final output

thank you, but to clarify what i am looking for.
- i would like to move the second line of transact column, up to line who contain the date. like that , i will get 2 value for the same date.
That's very different from splitting the column.
One solution: (Paste code into Advanced Editor)
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjTQByIjAyNjJR2l/LxUIAlkxupEK0H4SUAKzDU01AciqMKS8nyQQhOYQiAfodBIH4hgCjOKUsFmmsKVgkQgimMB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [date = _t, transaction = _t, value = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"date", type date}, {"transaction", type text}, {"value", Int64.Type}}), #"Add Shifted Transactions" = Table.FromColumns( {#"Changed Type"[date]} & {#"Changed Type"[transaction]} & {List.Skip(#"Changed Type"[transaction])} & {#"Changed Type"[value]}, type table[date=date, transaction.1=text, transaction.2=text, value=number]), #"Filtered Rows" = Table.SelectRows(#"Add Shifted Transactions", each ([date] <> null)) in #"Filtered Rows"Data
Results
thank you, could you explain me what wrong with my code?
i try to learn from my mistake and your code look very sophisticated for me.
Your code is not appropriate for your problem. Your problem isn't to split the column (which your code would do, if each cell had a string which included a linefeed character). Splitting the column means taking each cell and splitting it into two columns. But that's not what you really want to do. What you want to do is much better stated in your follow-up post to which I responded: "move the second line of transact column, up to line who contain the date."
is the solution work for this case :
You need to figure out what you want and express it clearly. You also need to provide data examples that encompass the variability you might have, and what you really expect for results. In a previous post, you wrote: " would like to move the second line of transact column, up to line who contain the date. like that , i will get 2 value for the same date." How do you expect ot get 2 value for the same date in this new example? What do you really want for results?
