JSON columns allow you to store complex, structured data that contains multiple related pieces of information. They display a preview of your data in the sheet view and offer a detailed side panel view when clicked, making it easy to work with complex information.Unlike simple text or number columns, JSON columns keep all related information together in a structured format. This is especially useful for storing information from external systems, API responses, or any data that has multiple parts that should be kept together (like contact details with addresses, phone numbers, and social profiles all in one column).
