Just shooting without knowing your real needs - take this with a grain of salt. Store some parsed representation that makes it easier for you to work with (probably normalized). Keep an archive of raw data somewhere. That may be another column, table or even S3 bucket. Don't worry about schema changes but you need to not lose the original data. There are some pitfalls to schema migrations. But the schema should be the representation that works for you _at the moment_, otherwise it'll slow you down.
