it is possible to retrieve data from your bases in JSON per SeaTable API. The request you need is called “List Rows”.
I would recommend you to read the SeaTable API Reference carefully to get well usage of the SeaTable API. If you are using Postman it would be benificial for you, as you can directly import the hundreds of SeaTable APIs with one click “Run in Postman” (on the top right corner of the webpage above).
Notice that if you are using SeaTable Cloud, we have a limitation of 100 API calls per minute for the rows request. If you are using self-hosted, you can elevate this limit by changing the server settings according to the manual at dtable_server_config - SeaTable Admin Manual.
Another possibility would be, to export your tables to Excel. To do this, go to a table and click on “Export table to Excel” from the table’s menu.
Do it like thousands of other people who have used SeaTable to develop powerful processes and get their ideas and tasks done more efficiently.
