You can use the BarcodeEngine class in the LEADTOOLS SDK to allow you to create QR codes in bulk. You can then export the changes into an Excel file using the RasterCodecs Save method. You can try building on the following code: static BarcodeEngine barcodeEngine = new BarcodeEngine(); static void Main( string [] args) { using (RasterImage image = RasterImage.Create(800, 800, 24, 300, RasterColor.White)) { WriteQRBarcode(image); SaveImage(image, @ "C:	emp\WriteQRCodes.xlsx" ); } } static void WriteQRBarcode(RasterImage image) { QRBarcodeData data = new QRBarcodeData { SymbolModel = QRBarcodeSymbolModel.Model1AutoSize, Symbology = BarcodeSymbology.QR, Value = "QR Data Value" , Bounds = new LeadRect(10, 250, image.ImageWidth, image.ImageHeight) }; QRBarcodeWriteOptions options = new QRBarcodeWriteOptions { GroupNumber = 0, GroupTotal = 0, XModule = 30, ECCLevel = QRBarcodeECCLevel.LevelL, HorizontalAlignment = BarcodeAlignment.Near, VerticalAlignment = BarcodeAlignment.Near }; barcodeEngine.Writer.WriteBarcode(image, data, options); } static void SaveImage(RasterImage image, string outputFilename) { using (RasterCodecs codecs = new RasterCodecs()) codecs.Save(image, outputFilename, RasterImageFormat.Xlsx, 0); Console.WriteLine( string .Format( "The barcodes have been written and saved to {0}" , outputFilename)); } https://www.leadtools.com/help/sdk/v21/tutorials/barcode/cross-platform/dotnet-core/write-1d-and-2d-barcodes-to-an-image.html https://www.leadtools.com/help/sdk/v21/dh/co/rastercodecs-save.html
