Is it possible to split an Excel sheet when converting from PDF to Excel?

ExecutionContext executionContext = ExecutionContext.Create(credentials);
ExportPDFOperation exportPdfOperation = ExportPDFOperation.CreateNew(ExportPDFTargetFormat.XLSX);

// Set operation input from a local PDF file
FileRef sourceFileRef = FileRef.CreateFromLocalFile(@"Sample.pdf");
exportPdfOperation.SetInput(sourceFileRef);

// Execute the operation.
FileRef result = exportPdfOperation.Execute(executionContext);

// Save the result to the specified location.
result.SaveAs(Directory.GetCurrentDirectory()
+ "/output/Sample.XLSX");
