This sample uses VBA to take values in the column A to generate QR Code barcodes using Bytescout BarCode SDK library.

Important: This demo uses VBA so if you have it disabled please temporary enable by going to Tools – Macro – Security.. and changing the security mode to “Medium” to Ask if you want enable macro or not. Then close and reopen this Excel document.

Barcodes generated in Excel using BarCode Generator SDK

You should have evaluation version of the ByteScout BarCode SDK installed to get it working. 

If you are getting error message like “File or assembly name Bytescout BarCode, or one of its dependencies, was not found” please try the following:

You may find this XLS file demo in the evaluation version of the SDK in ByteScout SamplesBarCode SDKMS Excel sub-folder    

Here is the VBA Code:

ces used
Bytescout Barcode SDK

‘ ==============================================================
‘1) Add the ActiveX reference in Tools -> References
‘2) Loop through the values from the Column A for which barcode has to be generated
‘3) Parse the value to Bytescout Barcode Object to generate the barcode using QR Code barcode type.
‘4) Save the generated Barcode Image
‘5) Insert the Barcode Image in the Column B
‘6) Repeat the steps 3 to 5 till the last Value in Column A
