Hello @lbendlin I will try explaining with clear data:

Data 1	Data 2	Data 3	Data Results
1	00		00-25
1		25	00-25

Data 1- In this cell must contain the information of device identification of my analysis;

Data 2 - In this cell must contain an information of others that I need;

Data 3 - In this cell must contain an information of others that I need;

Data Result - This cell I need make a form that should merge the information of column Data 3 with Data 2;

My problem is that in the line that Data 3 have information, Data 2 haven’t, or if Data 2 have information, Data 3 haven’t, how I need merge information of distinct lines I don’t know make this.

You can help me? 

Thanks for attention

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTIwABIKYIaukalSrA5EGCQC5MKFYwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Data 1" = _t, #"Data 2 " = _t, #"Data 3 " = _t, #"Data Results" = _t]),
    #"Replaced Value" = Table.ReplaceValue(Source," ",null,Replacer.ReplaceValue,{"Data 2 ","Data 3 "}),
    #"Added Custom" = Table.AddColumn(#"Replaced Value", "Results", each List.First(List.RemoveNulls(#"Replaced Value"[#"Data 2 "])) & "-" & List.First(List.RemoveNulls(#"Replaced Value"[#"Data 3 "])))
in
    #"Added Custom"

this part

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTIwABIKYIaukalSrA5EGCQC5MKFYwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Data 1" = _t, #"Data 2 " = _t, #"Data 3 " = _t, #"Data Results" = _t]),

[diegolima]

Ok @lbendlin  after step, I see this error:

Expression.Error: O nome 'Source' não foi reconhecido. Certifique-se de que ele foi soletrado corretamente.

At the Power Query = Table.ReplaceValue(Source," ",null,Replacer.ReplaceValue,{"Data 2 ","Data 3 "})

I do not know what to do.

Each step in Power Query can reference some other step.  In this case the step is referencing a step called "Source"  which is not present in your code (likely because you use the portuguese word for it).

You may want to invest some time in learning Power Query basics.
