Scanning the code offers to add the event, with its time and place, to the phone’s calendar.
One code per row. Columns: value (what the code contains), description (optional), type (optional: qr, code128, ean13, ean8, upc, code39, itf14, codabar). Comma, semicolon or tab separated, as Excel and Google Sheets save it.
Keep the details short: every extra word makes the code denser. Put long information on a web page and use a normal link QR code instead.
Most Android phones and current iPhones offer to add the event when scanning with the camera. Some older phones need a QR scanner app. Test with the phones your audience uses.
The time is saved as local time, so the event appears at the same clock time in the calendar of whoever scans it. That suits events people attend in person.
Yes. Batch from CSV with the columns title, start, end, location, details; write times as 2026-06-20 18:00.
