    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,

This M code works

let
    Source = Excel.CurrentWorkbook(){[Name="Data"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Customer ID", type text}, {"Amount", Int64.Type}}),
    #"Inserted Absolute Value" = Table.AddColumn(#"Changed Type", "Absolute Value", each Number.Abs([Amount]), Int64.Type),
    #"Merged Columns" = Table.CombineColumns(Table.TransformColumnTypes(#"Inserted Absolute Value", {{"Absolute Value", type text}}, "en-IN"),{"Customer ID", "Absolute Value"},Combiner.CombineTextByDelimiter(";", QuoteStyle.None),"Merged"),
    #"Grouped Rows" = Table.Group(#"Merged Columns", {"Merged"}, {{"GroupTables", each _, type table [Amount=nullable number, Merged=text]}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "CountRows", each Table.RowCount([GroupTables])),
    #"Filtered Rows" = Table.SelectRows(#"Added Custom", each ([CountRows] = 1)),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Filtered Rows", "Merged", Splitter.SplitTextByDelimiter(";", QuoteStyle.Csv), {"Merged.1", "Merged.2"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Merged.1", Int64.Type}, {"Merged.2", Int64.Type}}),
    #"Removed Columns" = Table.RemoveColumns(#"Changed Type1",{"GroupTables", "CountRows"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Merged.1", "Customer ID"}, {"Merged.2", "Amount"}}),
    #"Changed Type2" = Table.TransformColumnTypes(#"Renamed Columns",{{"Customer ID", type text}})
in
    #"Changed Type2"

Hope this helps.
