Sometimes you need one QR. Sometimes you need 500: one per asset, one per seat, one per package. Here's how teams handle batch QR generation today, and where the Zen QR generator fits.
One row per QR. Required columns: a stable unique identifier (asset ID, seat number, SKU), the QR payload (URL, text, etc.), and a human-readable label that gets printed next to the code. Bad spreadsheets are the source of 90% of batch-QR pain — sort by identifier early, dedupe early.
Encode the unique identifier in a stable URL: example.com/asset/{id}. The destination page can change behavior without reprinting any QR. Don't encode raw asset metadata in the QR — your asset metadata changes; your QR pattern can't.
Avery sheet templates (5160, 5263, etc.) work for ~30-200 codes per sheet. For 500+, switch to roll-printable labels and a label printer. Always include the human-readable identifier under the QR — it's invaluable when someone's phone fails to scan and they have to type the ID manually.
The on-page generator is one-at-a-time today. The /api/qr/generate endpoint takes a single text + style and returns a PNG — script around it with curl or Node.js to batch through your spreadsheet rows. A native batch UI (CSV upload → ZIP of PNGs) is on the roadmap; reach out if you'd find it useful.
One row per QR. Required columns: a stable identifier (asset ID, SKU, seat number), the QR payload (URL, text, etc.), and a human-readable label printed next to the code.
Use example.com/asset/{id}. The destination page can change behavior without reprinting any QR. Don't bake metadata into the QR — it changes; the QR can't.
Loop your CSV rows, POST each row's text to /api/qr/generate, save the returned dataUrl as a PNG. A bash + curl script fits in ~20 lines.

Print the identifier under each QR — invaluable when a phone fails to scan and the user has to type it manually.
