Bulk QR code generator from a CSV or a pasted list

How to use the bulk QR code generator

1. Export your sheet from Excel or Google Sheets as CSV with a header row, then click Upload CSV. If you only have a list of links, paste them into Or paste one entry per line instead.
2. Map the columns: Content column for the link or text, and optionally Label column for captions and Filename column for file names.
3. Choose the Content type: URL, Text, Wi-Fi (columns ssid, password, encryption) or Contact (mapped columns).
4. Pick a Style preset and the Output: PNG, SVG or PNG + SVG. Tick Include CSV manifest and choose a Label sheet PDF layout, A4 3×8 or Letter 2×5, if you want one.
5. Check the first five previews and the validation report, then click Generate ZIP. Use Cancel if you need to stop.

Bulk QR code generator details

The bulk tool runs the same encoder and styling engine as the single-code pages once per row in a background worker, then packs the results into a ZIP, all on your device.

Preparing the CSV

Export from Excel or Google Sheets as CSV with a header row. The parser handles quoted fields, Windows line endings and the byte-order mark Excel writes at the start of the file. One column holds the content; others can hold a label and a file name. If you only have a list of links, skip the file and paste them into the text box, one per line.

Content types

URL rows are normalised like the single generator: https:// is added when missing and spaces are flagged. Text rows are encoded as they are. Wi-Fi batches need columns named ssid, password and encryption, one network per row. Contact batches map columns to vCard fields such as name, organisation, phone and email, one person per row.

Limits, validation and speed

The limit is 1,000 rows per batch, with a warning above 300 because the ZIP and the label sheet grow accordingly. Rows that fail validation are listed with the reason and skipped; the rest of the batch continues. The first five codes are previewed before you generate anything. A 500-row batch of plain URL codes finishes well under a minute on a laptop, with a progress bar and Cancel while it runs.

Verification

By default the first, the last and every 25th code are decoded with the ZXing engine and compared byte for byte with their source rows; decoding every code would roughly double the time and is available as an option. Because all rows share one style, a passing sample means the style is safe, and a failing one, typically an oversized logo or a pale colour, stops you before you print a thousand bad labels.

The ZIP, names and label sheets

Files are named qr-{type}-{label}.png or .svg, taking the label from the Filename column when mapped, otherwise the Label column, otherwise a slug of the content. Include CSV manifest adds a CSV listing each row’s content, label, file name and result. Label sheet PDF lays the codes out with captions on A4 (3 by 8, 24 per page) or Letter (2 by 5, 10 per page) for sticker sheets and shelf labels. Check any file afterwards with the QR code reader, and read the size guide before choosing a label size.

This code never expires

Each file in the ZIP holds its own row's content as a plain static code, so a batch of a thousand labels keeps working without any service behind it. This is a static QR code: the data is written into the pattern, so scanning it needs no server, no account and no subscription. There is nothing to renew and no redirect that can be switched off, which is why a code made here keeps working for as long as the printed copy exists. The trade-off is honest: a static code cannot be edited after printing and does not count scans. If you need either, encode a link to a page you control. Read how static and dynamic codes differ, and if a code you already have has stopped working, see why QR codes expire.

Styling, formats and print size

Every code can be styled in the Style panel: six dot shapes, corner shapes, solid or gradient colours, a transparent background, a quiet zone of 0–8 modules, and your own logo up to 30 percent of the width. A contrast checker warns below 3:1 and blocks downloads below 1.5:1, and after each change the preview is decoded again so the badge tells you whether the styled code still scans.

Print size: as a rule of thumb the code should be at least one tenth of the scanning distance wide, with the quiet zone included.

Label sheets place each code with its caption on A4 (3×8) or Letter (2×5) at a size suited to stickers and shelf labels; for larger prints use the SVG files from the ZIP.

The QR code size guide has a calculator for module size, DPI and distance.
