Hi, Hamidrezaei

Based on your descirption, I created data to reproduce your scenario. The pbix file is attached in the end.

Test(row 4 and row 6 both have spaces):

You may add steps in Power Query as below.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlRwVHBWitWJVjJScFFwA7OMFVwV3MEsBTBpquCh4AnhAwViAQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
    Custom1 = Table.ReplaceValue(#"Changed Type"," ","",Replacer.ReplaceText,{"Column1"}),
    Custom2 = Table.AddColumn(Custom1,"Custom2",each if Text.Length([Column1])=0 then null else [Column1]),
    #"Removed Columns" = Table.RemoveColumns(Custom2,{"Column1"})
in
    #"Removed Columns"

Result:

Hi, Hamidrezaei

You may try the following codes in 'Advanced Editor'. The pbix file is attached in the end.

    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
    Custom1 = Table.AddColumn(#"Changed Type","New Column",each if Text.Length(Text.Replace([Column1]," ",""))=0 then null else [Column1]),
    #"Removed Columns" = Table.RemoveColumns(Custom1,{"Column1"})
in
