how can i replace numeric value by string value

Hi Gaddam ,

You can create a custom column that is "N/A" if the value of the base column is equal to -1, otherwise it is the current value of the base column. You can then delete the base column and rename the new column.

You can click "Advanced Editor" to copy and paste the following code and check the steps in the right step bar.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WctZ1NlDSUdI1BBJGSrE6YBFDmAiQgAoZwYRMzWBCxkCeoYEBQlmgbiBIBUjEEiYA0mcKEjE1VYqNBQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Name = _t, Min = _t, Max = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Name", type text}, {"Min", Int64.Type}, {"Max", Int64.Type}}),
    #"Added Conditional Column" = Table.AddColumn(#"Changed Type", "_Min", each if [Min] = -1 then "N/A" else [Min]),
    #"Added Conditional Column1" = Table.AddColumn(#"Added Conditional Column", "_Max", each if [Max] = -1 then "N/A" else [Max]),
    #"Removed Columns" = Table.RemoveColumns(#"Added Conditional Column1",{"Min", "Max"})
in
    #"Removed Columns"

Hi,

You should avoid doing that because that will give rise to multiple data types in those columns.  If you really do not want to see the -1, then replace them with null in the Query Editor.
