Export Google Chart in Excel using Javascript ASP.NetC#

I have resolved it. For Image URI Data base64, saved in a file and then called the file as usual to export in excel.


To Save File:

public string CreateImage(string data)
{
string fname = Server.MapPath("data-image") + "//chart.png";
var base64Data = Regex.Match(data, @"data:image/(?<type>.+?),(?<data>.+)").Groups["data"].Value;
var binData = Convert.FromBase64String(base64Data);
using (var stream = new MemoryStream(binData))
{
System.Drawing.Bitmap img = new Bitmap(stream);
img.Save(fname, System.Drawing.Imaging.ImageFormat.Png);
}
return fname;
}
