Note: If garbled characters appear when a local Json file is used, save the file in the UTF-8 encoding and upload it again..
Also, if a column with the same name is detected, only the column that appears first is retained, whereas the data from the column with the same name is discarded.

Web-based JSON Data Source

When the Source Type of the JSON data source is Web, you may need to setup an HTTP service on your own to return JSON data. You can use any programming language or platform for this HTTP service to return the JSON data content, for example.


The content returned by the above URL is as follows. Web-based JSON Data Source

Note: Pay attention to the structure of JSON data. The root node should be a collective entity name, such as users. Its content is an array, and each array element is an instance of another entity class (such as user), expressed in the form of attribute key-value pairs.
