SpreadJS supports the WEBSERVICE and FILTERJSON functions.

The WEBSERVICE function returns string data from a web service on the Internet or Intranet that supports CORS (Cross-origin resource sharing).

The FILTERJSON function parses a valid json string into a value, an object or an array of objects. This result also supports vertical spill.

WEBSERVICE If the request doesn' t follow the Same origin policy and the target website doesn' t support CORS(Cross-Origin Resource Sharing) from source origin, will return #VALUE! error. The function result is a string. FILTERJSON FILTERJSON function can parse a JSON string into a scalar value, an object or an array of objects(can spill vertically). You can both use FILTERJSON function and WEBSERVICE function to get the json object from server and use in SpreadJS.
