Processing Twitter JSON Data

Article #: Product: Version:

Summary

JSON data format is widely used in modern client/server applications such as Twitter due to its compactness over XML and its data-centric design.

Resolution

The DMExpress JSON Reader task enables JSON data to be treated as a DMExpress source. Specifically, the JSON Reader converts a UTF-8 JSON source into a UTF-8 CSV (comma-separated values) output, which can then be read by other DMExpress tasks.

The attached example contains the following:
