    Hi, rangeet1 ;

    Try it;

    let  
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8vAzMDBX0lFSUTA1UIrVQRYwQxcwRxewQBfQxTBEF2qKc6iBgQVYxAhdwBhdwARdwNAAXUQXLBQLAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Customer ID" = _t, Amount = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Customer ID", type text}, {"Amount", type text}}),
    #"Replaced Value" = Table.ReplaceValue(#"Changed Type","$ ","",Replacer.ReplaceText,{"Amount"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Replaced Value",{{"Amount", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type1", "Original", each [Customer ID]&" "&Text.From([Amount])),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Opposite", each [Customer ID]&" "&Text.From([Amount]*-1)),
    #"Added Custom2" = Table.AddColumn(#"Added Custom1", "Custom.2", each if List.Contains(#"Added Custom"[Original],[Opposite]) then "" else 1),
    #"Filtered Rows" = Table.SelectRows(#"Added Custom2", each ([Custom.2] = 1)),
    #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Original", "Opposite", "Custom.2"})
in
    #"Removed Columns"

    The final output is shown below:

Hi, rangeet1;

You could complete it in power query .

1.add custom column.

= Table.AddColumn(#"Changed Type", "Original", each Number.ToText([Customer ID]) &" "& Number.ToText( [Amount]))

2.add another custom column.

= Table.AddColumn(#"Added Custom1", "Opposite", each Number.ToText([Customer ID]) &" "& Number.ToText( [Amount]*-1))

3.add 3rd custom column.

= Table.AddColumn(#"Added Custom", "Flag", each if List.Contains(#"Added Custom"[Original],[Opposite]) then "" else 1)

4.filter rows.(1)

5.remove columns.

The final output is shown below:

let  
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjQwUNJRMjVQitWBccyQOebIHAtkji6KJl24LkMgzwiZY4zMMUHmgLQieLpgbiwA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Customer ID" = _t, Amount = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Customer ID", Int64.Type}, {"Amount", Int64.Type}}),
#"Added Custom1" = Table.AddColumn(#"Changed Type", "Original", each Number.ToText([Customer ID]) &" "& Number.ToText( [Amount])),
#"Added Custom" = Table.AddColumn(#"Added Custom1", "Opposite", each Number.ToText([Customer ID]) &" "& Number.ToText( [Amount]*-1)),
#"Added Custom2" = Table.AddColumn(#"Added Custom", "Flag", each if List.Contains(#"Added Custom"[Original],[Opposite]) then "" else 1),
#"Filtered Rows" = Table.SelectRows(#"Added Custom2", each [Flag] <> null and [Flag] <> ""),
#"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Original", "Opposite", "Flag"})
in
#"Removed Columns"

I have tried to follow these steps. However, the last step is taking a lot

of time to load.
Thanks
