Guides
Everything here is written from the actual behaviour of the bulk QR code generator on this site — real settings, real CSV examples, and the failure modes that actually come up when you print a few hundred codes.
Getting codes out of the generator
- How to generate QR codes in bulk from a CSV file The complete walkthrough: preparing the spreadsheet, choosing columns, and getting a usable ZIP back.
- How to paste a list of URLs and get QR codes back No CSV needed. Paste two spreadsheet columns straight across, and the comma rule that catches people out.
- How to print a sheet of identical QR codes When you need forty copies of one code for table tents, shelf edges or handouts.
- How to put multiple different QR codes on one sheet Labelled contact sheets, how the grid gets chosen, and when individual files are the better answer.
Getting the output right
- What size should a QR code be for printing? From scanning distance to centimetres to pixels, and what 300, 600 and 1000 px actually measure on paper.
- QR code error correction levels explained What L, M, Q and H actually trade away, and which to pick for labels versus screens.
- How to generate bulk QR codes as SVG files Vector output for print: why it matters, and when PNG is the better choice.
- How to name QR code files from a spreadsheet column The difference between a usable batch and 400 files called qr_code_N.png.
When something goes wrong
- Why your QR code will not scan The causes in the order they actually happen: size against distance, quiet zone, contrast, surface and URL length.
- Fixing CSV upload problems Every error message and what it means — plus the silent failures that generate the wrong codes without warning.
- How to format a CSV for bulk QR code generation Headers, encoding, commas inside URLs, and the Excel export settings that cause trouble.
Planning a project
- Static vs dynamic QR codes What you are actually paying for, and how a redirect on your own domain gives you editable destinations without a subscription.
- QR codes for asset tags and inventory labels What to encode on an asset label, what size to print, and how to survive a warehouse.
- QR codes for event badges and name tags One code per attendee, named so your badge mail merge finds the right image.
- QR codes for restaurant menus and table tents Sizing for a seated diner, matte lamination, and keeping the destination editable when the menu changes.
- QR codes for product packaging and labels Per-SKU codes, vector output for the print shop, and surfaces that fight back.
