View -> JSON -> Excel report

Usually I (probably as all) used agent approach in web applications for making excel's reports. In my case I was asked to make some reports exporting all data from current view (reports should look like in view).

So I decided to use another approach (in my case it was JSON because I like it more). Here you could download the demo version how to receive data from LN database.
to receive all documents from view I used:
?ReadViewEntries&count=1000&Start=1&outputformat=json&ExpandView
to receive the name/title of columns I used:
?ReadDesign&Outputformat=json

and in the end of the story I used next code to create excel report

function appExcel(){
if (window.ActiveXObject){
var xlApp = new ActiveXObject("Excel.Application");
xlBook = xlApp.Workbooks.Add();

xlBook.worksheets("Sheet1").activate;
var XlSheet = xlBook.activeSheet;

XlSheet.cells(1,1).value = "value";
xlApp.visible = true;
}
}

This function works only in IE as far as I know.
