How can I export images from ASPxGridView to excel in .net?

You can convert the image data to Excel format using the Document conversion services from LEADTOOLS. You can create your own web-service that receives the image data from the client side, convert it to Excel using the DocumentConverter class from LEADTOOLS, and then you can either save the Excel locally on server, or pass it back to the client.
You can find an online demo that uses the document conversion service here:
https://demo.leadtools.com/JavaScript/DocumentViewer/
When you open the online demo, open your image and then select the menu "File\Export" to save the image as Excel (xls) format.

More details about the class can be found here:

Also, the following code shows how to convert image (JPEG, PNG, BMP, etc.) to Excel (xls) using the document converter class:

using (DocumentConverter documentConverter = new DocumentConverter())
{
string OcrAdvantageRuntimeDir = @"c:\LEADTOOLS 19\Bin\Common\OcrAdvantageRuntime";
documentConverter.Options.EnableSvgConversion = true;
documentConverter.Options.JobErrorMode = DocumentConverterJobErrorMode.Abort;
using (var ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Advantage, false))
{
var rasterCodecs = new RasterCodecs();
var documentWriter = new DocumentWriter();
ocrEngine.Startup(rasterCodecs, documentWriter, null, OcrAdvantageRuntimeDir);
documentConverter.SetOcrEngineInstance(ocrEngine, true);
documentConverter.Diagnostics.EnableTrace = true;
var inFile = @"C:\Users\Public\Pictures\Master.JPG";
var outFile = @"C:\Users\Public\Pictures\Master.xls";
var format = DocumentFormat.Xls;
var jobData = DocumentConverterJobs.CreateJobData(inFile, outFile, format);
jobData.JobName = "conversion job";
var job = documentConverter.Jobs.CreateJob(jobData);
documentConverter.Jobs.RunJob(job);
if (job.Status == DocumentConverterJobStatus.Success)
{
Console.WriteLine("Success");
}
else
{
Console.WriteLine("{0} Errors", job.Status);
foreach (var error in job.Errors)
{
Console.WriteLine(" {0} at {1}: {2}", error.Operation, error.InputDocumentPageNumber, error.Error.Message);
}
}
}
}
