Based on text in string lookup value from another table

Hello Anonymous 

you can add a new column to your data-table with this formula. KeyWords has to reference your data where your stored your keywords. If you have big data then there might some enhances needed

let
            CheckKeyWordColumn =Text.Combine( List.Transform(KeyWords[Keyword], (item)=> if Text.Contains(Text.Lower([URL]), Text.Lower(item)) then item else null),", "),
            GetCode = try Table.SelectRows(KeyWords, each [Keyword]= CheckKeyWordColumn)[Code]{0} otherwise null
        in 
            GetCode

Here a complete example

let
    Data = 
    let
        Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WyigpKSi20tcvLy/Xy60sT00qSExP1UvOz9XPrdQFsXWzUyvL84tSDHUz8nNT9YtLEotKlHSUfCsVwEwFkBqlWB1Uk/JLMlKL4CZ5Q0wwgmjWB5mjl1GSmwMxBsRFmJJakgwUVoqNBQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [URL = _t, Description = _t]),
        #"Changed Type" = Table.TransformColumnTypes(Source,{{"URL", type text}, {"Description", type text}})
    in
        #"Changed Type",
    KeyWords = 
    let
        Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjQwMDBU0lHyTq0szy9KMVSK1YEIGiEEjZRiYwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Code = _t, Keyword = _t]),
        #"Changed Type" = Table.TransformColumnTypes(Source,{{"Code", type text}, {"Keyword", type text}})
    in
        #"Changed Type",
    
    AddCode = Table.AddColumn(Data, "Code", each let
            CheckKeyWordColumn =Text.Combine( List.Transform(KeyWords[Keyword], (item)=> if Text.Contains(Text.Lower([URL]), Text.Lower(item)) then item else null),", "),
            GetCode = try Table.SelectRows(KeyWords, each [Keyword]= CheckKeyWordColumn)[Code]{0} otherwise null
        in 
            GetCode)
in
    AddCode

Hi Anonymous 

It depends on how you extract your Keyword from URL (how the URL constructs), this code is based on your sample, paste in Advanced Editor:

let
  Source = Table.FromRows(
    Json.Document(
      Binary.Decompress(
        Binary.FromText(
          "VcxBCoAgEAXQq4TrdKhlV4hOEC6shoQaFBsYvH2YEbT7H/5/86w8c7wGABExlAWX6HY0ayCgrEvWB2YJaeu0D4RwsUusWjXl5olN2Sjb/qXAHtMnjVXo6xmKYzzTWZlSX8Xe",
          BinaryEncoding.Base64
        ),
        Compression.Deflate
      )
    ),
    let
      _t = ((type nullable text) meta [Serialized.Text = true])
    in
      type table [URL = _t, Description = _t]
  ),
  LookupTable = Table.FromRows(
    Json.Document(
      Binary.Decompress(
        Binary.FromText("i45WMjQwMDBU0lHyTq0szy9KMVSK1YEIGiEEjZRiYwE=", BinaryEncoding.Base64),
        Compression.Deflate
      )
    ),
    let
      _t = ((type nullable text) meta [Serialized.Text = true])
    in
      type table [Code = _t, Keyword = _t]
  ),
  #"Changed Type" = Table.TransformColumnTypes(
    Source,
    {{"URL", type text}, {"Description", type text}}
  ),
  #"Added Custom" = Table.AddColumn(
    #"Changed Type",
    "Keyword",
    each Text.Proper(
      if Text.Contains([URL], "mywebpage") then
        Text.BetweenDelimiters([URL], "my-page-", "-")
      else
        Text.BetweenDelimiters([URL], ".com/", "/")
    )
  ),
  #"Added Custom1" = Table.AddColumn(
    #"Added Custom",
    "Code",
    each LookupTable[Code]{List.PositionOf(LookupTable[Keyword], [Keyword])}
  )
in
  #"Added Custom1"
