    Hi ,

    Please try:

    List.Select(Json.Document([ratings_and_unit_endorsements]),(record) => record[unit] = [unit]){0}[expiry_date]


    All steps:

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45Wiq6OUUqtKMgsqoxPSSxJjVGyilEyMjAy1jU01DWyjFHSiVEqSizJzEsHyzi6eIKFSvMyS8ACrhGRkTFKtTp4TDE2wDAlIBjVFH/fiAi8phjpGhgSNMUnxN8faEqskg6YqRQbCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ratings_and_unit_endorsements = _t, unit = _t]),
    AddExpiryDate = Table.AddColumn(Source, "Expiry Date", each List.Select(Json.Document([ratings_and_unit_endorsements]),(record) => record[unit] = [unit]){0}[expiry_date])in
    AddExpiryDate

I had to change it slightly so it takes into account both "unit" and "rating" and now it works.

Table.AddColumn(#"Renamed columns", "Expiry Date", each List.Select(Json.Document([ratings_and_unit_endorsements]),(record) => record[unit] = [unit] and record[rating] = [rating]){0}[expiry_date])


Thank you!
