Hello,

you can try to use:

window.open("data:text/csv;charset=utf-8," + data);

as data you can stringify any json data

or you can use filesystem api to save data to file:

var newDir, newFile;
    tizen.filesystem.resolve("documents", function(dir) 
            {
               newDir = dir.createDirectory("newDir");
               newFile = newDir.createFile("newFilePath.txt");
               newFile.openStream(
                         "w",
                         function(fs) {
            	           fs.write("test test test");
            	           fs.close();
            	         }, function(e) {
            	           console.log("Error " + e.message);
            	         }, "UTF-8");
            });
