Hi Charles,
Not directly in the current version. However, you can download the CodeSiteJsonLogging unit from the Downloads section of my Delphi By Design blog (https://delphibydesign.com/downloads/). At the bottom of the page, in the CodeSite section, you will find the entry for the CodeSite JSON Logging download.
By the way, the next major release of CodeSite will have integrated support for JSON.
