## Summary
A bulk QR code generator turns a list into many codes in one pass. Paste one entry per line — optionally with a label after a comma — and every code is generated in your browser. Download them individually or as a single labelled contact sheet for printing.

## 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.

## Frequently asked questions
### How many codes can I generate at once?
Up to 500 per batch here, which covers most practical print jobs. Split larger lists into batches, or generate them in your own pipeline.

### Can I upload a CSV file?
Paste the column contents directly — one value per line, with an optional label after a comma. That covers the same ground without an upload.

### Are the codes unique?
Each code encodes exactly the line you provide, so uniqueness comes from your list. For tickets, generate unique identifiers before pasting them in.

### Can I print them on label sheets?
Yes. The contact sheet is laid out in a regular grid you can scale to standard label stock, and each code can also be exported individually.
