One code per line, label after a comma

The simplest input is a plain list of URLs or text values:

https://example.com/asset/0001
https://example.com/asset/0002
https://example.com/asset/0003

Add a label after a comma and it is printed under the code on the sheet, which is what makes a batch usable when you come to stick them on things:

https://example.com/asset/0001, Compressor A
https://example.com/asset/0002, Compressor B
https://example.com/asset/0003, Pump 4 — plant room

Values containing a comma should be wrapped in double quotes. Blank lines are ignored.

Where a list of codes beats one code

• Asset registers. One code per item, each linking to that item's maintenance record.
• Event tickets. One unique code per attendee, validated against a list at the door.
• Table numbers. Each table's code carrying its own identifier so orders route correctly.
• Product serials. Codes matching a serial range for warranty registration.
• Classroom and library labels. One per book, box or locker.
• Sample tracking. Lab or field samples where the label must survive without a network.

For a genuinely large job — tens of thousands of codes, or codes generated on demand as records are created — you want this in your own pipeline rather than a browser tab, using one of the open-source QR libraries available for every major language.
