Large data set export into excel sheet

[megastream]

I have an issue with the large data set export into an excel sheet.  I am export 13k product into excel sheet using  blob = this.exportData({}); but it's not working properly it's working only for small data set. 

So please provide necessary solution regarding this

 blob = this.exportData({
                    url: "ajaxurl",
                    filename: JSON.stringify({
                        'filename': filename,
                        'ids': ids,
                        'groupIds': groupIds
                    }),
                    // render: true
                });
 if(typeof blob === "string"){ blob = new Blob([blob]);}
saveAs(filePath, exportedFileName);

it's not passing $_POST['pq_data'] value into API method so, it's not generating Xls file. but when I am trying with some of the selected row ex  1-100 records then it's working fine.

Thank you for your reply.

I am using the $_POST['pq_data']  variable under the API method for getting the selected row HTML which is using for generating an excel-sheet.
