Bulk QR code generator

When you need ten, a hundred or a thousand codes instead of one, each with different content:

• Restaurants: a menu or ordering link per table (…/order?table=12).
• Warehouses and inventory: SKU, bin-location and asset labels in QR or Code 128.
• Events: named tickets and registration IDs.
• Online shops and packaging: a product-page link or EAN-13/UPC barcode for every product.
• Real estate and listings: each property's own listing link.
• Schools and clubs: contact cards, membership cards, equipment tags.

Every code is static: the content lives inside it, with no provider in between, no expiry, and no per-code fee or subscription. Elsewhere, bulk generation is usually locked behind a pricier plan.

When you paste a table, the generator detects the delimiter (comma, semicolon or tab) and reads the first row as headers if it looks like one.

Content from a column: every row of, say, the “link” column becomes one code.

Content from a template: if each code needs a fixed part plus a variable one, write a template, and the column name in curly braces is replaced with that row's value:

https://myrestaurant.com/order?table={table}

You can also refer to columns by number: {1}, {2}. Pick separate columns for the file name (an SKU, for instance) and the caption under the code (“Table 12”).

Empty or invalid rows (an EAN with a wrong check digit, say) are skipped, and at the end we list each one and why.

Output	Best for
ZIP (PNG, SVG, PDF or EPS)	one file per code, named your way, for designers and print shops
Multi-page PDF	one code per page with its caption, for review or one-by-one printing
Label sheets	printing on self-adhesive sheets, with cut marks

Label presets are built for A4 sheets: 21 (63.5 × 38.1 mm), 24 (70 × 37 mm), 40, 65 (38.1 × 21.2 mm), 10 and 8 per sheet. For US Letter or any other stock, enter a custom layout (columns, rows, label size, margins). Skipped rows don't leave gaps on the sheet.

Printing tip: print the PDF at 100% (“actual size”), not “fit to page”, or the codes will drift off the labels. Do a test print on plain paper first and hold it against the label sheet toward a window.

QR codes get the same designer as the QR code generator: 12 templates, module shapes, eyes, colors, gradients, a logo and a frame with a call to action. Set the design once, and every one of your hundreds of codes matches.

Or switch to barcodes: EAN-13, EAN-8, UPC-A, Code 128, Code 39, ITF-14. For EAN and UPC we calculate a missing check digit and flag a wrong one.

We read the first finished code back with two independent decoders and compare it with the row's content. If that fails (say, the design is too adventurous), you hear about it before the full run. Before printing, scan a few random codes from the finished sheet too.

Your spreadsheet never reaches a server: reading it, making the codes and building the ZIP or PDF all happen in your browser. Names, ticket IDs and internal SKUs are safe to use.

• Up to 2,000 rows per run; do the rest in another run.
• You see progress as it runs and can stop at any time.
• On an average laptop, a few hundred codes take seconds; high-resolution PNGs and logos take longer.
• We don't open XLSX files directly: select and copy the rows in Excel, or save as CSV.

No sign-up, no watermark and no per-code limit within the 2,000 rows.
