Bulk QR Generator

The CSV workflow, step by step

Step 1 — build the spreadsheet. Put a short label in the first column (it becomes the file name) and the content to encode in the second, then export as CSV from Excel, Numbers or Google Sheets. Keep labels free of slashes and other characters that file systems dislike.

Step 2 — upload the file above and pick the content type so the generator interprets the values correctly, whether they are URLs, phone numbers, WhatsApp links or WiFi credentials.

Step 3 — choose PNG, SVG or PDF, then start the run. A progress bar shows how far along the batch is, and a cancel button stops it cleanly if you spot a mistake in the data.

Step 4 — download the ZIP, or grab individual codes from the results list. Spot-check two or three files with the QR code decoder before handing the set to a printer or uploading it to a catalogue.

Where bulk generation saves real time

Product catalogues are the clearest case: one code per SKU pointing at its product page, generated in a single pass instead of one at a time, then dropped into label artwork by file name.

Events use it for per-ticket or per-session codes — a code for each workshop's feedback form, or a code per exhibitor stand pointing at their profile.

Property and rental portfolios generate a code per listing for signage, and asset registers generate a code per item for maintenance records or serial-number labels.

Multi-location businesses build one code per branch — separate review links, WiFi credentials or contact numbers — with file names that match each site, so the right code reaches the right store.

Working with large batches without locking up the page

Generation runs on your device, so the practical limit is memory rather than a server quota. The tool renders codes one at a time and yields back to the browser between them, which keeps the interface responsive and lets you cancel mid-run without leaving a half-written download.

For very large sets, split the CSV into chunks of a few hundred rows. Smaller ZIPs are quicker to download, easier to check, and far less painful to regenerate if you spot a data error after the fact.

Before a print order, decode a sample from the middle of the batch as well as the first row — errors in spreadsheets tend to appear where a formula was dragged, not at the top.
