2HAC Studio just had a breakthrough. You can generate 10000, 100000 QR Codes and Barcodes or even more with Bulk Barcode QR Code Generator for Google Sheet and Bulk Barcode QR Code Generator & Mail Merge. You just set up the Google Sheet data and form, and then click Save to PDF or Save to Sheet button and wait. It is very fast when generating PDF. For saving to sheet, it takes more time. We don't charge more for this feature. You just buy addon with an affordable price and enjoy.
