In D a file with the extension *.json is used to describe packets that are included in your project, the dependency manager DUB.

For example, you can install Eclipse with DDT and create a project with DUB. The file dub.json write the following:
-----
{
    "name" : "myDupApp",
    "description" : "Carbon - Test.",
    "dependencies" : {
        "carbon": "~>1.4.1"
    }
}
-----

Save the file (Ctrl + S). Then in your project with DUB downloaded package `carbon`:
http://code.dlang.org/packages/carbon

After that you can safely use the package `carbon`:
-----
import std.stdio, carbon.linear;;

void main() {
    auto m = matrix!(2, 3, (i, j) => i * 3 + j);
    writeln(m); // [[0, 1, 2], [3, 4, 5]]
}

Thank you for answering me so fast , where do I get the DUB for windows ?

There is also the .json file that is produced by dmd's -X command line switch:

    dmd -X foo.d

That outputs the members of the source code to foo.json in a way that may be useful for a tool.
