I’ve had good luck storing JSON strings in long text fields. Sure, attachments seem easier at first, but they’re a pain when you need to search or reference the data later. I keep the raw JSON in a long text field, then pull out the important key-value pairs into separate fields for stuff I query often. This way you get the best of both worlds - easy access plus searchable data. Just make sure your JSON is clean because messy formatting will bite you later.
