Can Standard edition load JSON or not?

According to the editions page ( … ions.shtml) both the Standard and Pro editions of the grid can load data from JSON. Yet, to load JSON, you need the file dhtmlxgrid_json.js that is only included in the Pro download.

What is DHTMLX’s policy? Is the editions page correct, and the file should come with the Standard download? Or is the editions page wrong, and the download correct?

I have the file in question after buying a license for another project, but I need to know if I can use that file in a project which uses the Standard license.

the dhtmlxgrid_json is included only in PRO version of dhtmlxGrid.
