jFiles adds JSON support to Clarion. It contains classes that let you create, and consume data files formatted as JSON.

JSON (JavaScript Object Notation) is a semi-formatted structure used for moving data between programs. It is more structured (and easier to deal with) than CSV but less verbose then XML. Thus it is especially popular as a format used to interchange data over the internet - either between a browser and a server, between a WebService and a client, or between a mobile device and a web server.

jFiles makes it really easy to move data between common Clarion structures (Table, Queue, View, Group) and JSON "strings". These strings could be in memory (suitable for being sent out over the internet) or stored as files on the disk.

Online Code Generator

jFiles makes possible an online Clarion Code generator for JSON loading and saving. This tool inspects some JSON that you provide, and then generates appropriate Clarion structures, and jFiles code, for creating or consuming that JSON. This greatly reduces the time it takes to use JSON in your program.

Requirements & Recommendations

jFiles requires StringTheory 3

If you are creating NetTalk Web Services, and you want to use jFiles to create and consume the JSON in those web services, then you need NetTalk build 8.42 or later.


jFiles is derived from code written by Dries Driessen. It is used here under license.
