Bulk 2D Barcode Generator from CSV

How to use the Bulk 2D Codes generator

1
Download the 2D template
The template has Matrix Data, Symbology, Label / Filename and Notes columns. Fill it in Excel, Google Sheets or your own tool and save it as CSV or XLSX.
2
Upload and check the preview
Every row renders a symbol in the preview. Fix the rows that report an error before exporting, since a bad value usually means a character the symbology cannot carry.
3
Export the batch
Take the ZIP of vector SVG files for artwork, PNG for label software, or the PDF sheet when someone needs to print and cut.

Features

Per-row symbology column: datamatrix, aztec, pdf417, dotcode or microqrcode
Your own label column decides every filename in the download
ZIP of PNG or SVG files, a results sheet, or a printable PDF
Rows that fail validation are reported instead of silently skipped
The spreadsheet is parsed in your browser and never uploaded

How the 2D template works

Column	What it does
Matrix Data	The payload for that row: a GTIN and serial, a URL, a part number
Symbology	datamatrix, aztec, pdf417, dotcode or microqrcode, set per row
Label / Filename	The name of the exported file, so the symbol matches your record
Notes	Free text carried into the results sheet for the person doing the printing

Flow diagram from a spreadsheet of 2D code values through row validation to a ZIP of generated symbols — Each row is validated, rendered and named independently, so one bad value cannot spoil the batch.

Choosing a symbology per row

Mixing families in one run is the point of the 2D template. A parts list might need Data Matrix for direct part marking, PDF417 for the paperwork that travels with the pallet, and DotCode for the carton printed on the line. Each row is rendered by its own symbology, so you download one folder that matches the job.

Where a customer specification names the symbol, follow it. The families differ in capacity, minimum print size and which readers handle them, and those differences are decided by the scanner already installed, not by preference.

Getting a clean batch

Keep one value per row and no stray spaces; padding characters change the payload.
Use a label column that is unique, or files overwrite each other in the ZIP.
Set the module size for the smallest symbol in the run, then check the longest payload separately.
Spot-check the first, middle and last rows against the source sheet after exporting.

Limits worth knowing

Rendering happens in your browser tab, so a very large run is bounded by the memory of the machine rather than by a quota on our side. Splitting a few thousand rows into separate files is usually faster than pushing one enormous sheet through and waiting.

The tool produces symbols from the values you supply. It does not assign identifiers, check that a GTIN belongs to you, or validate a serialization scheme against a regulatory database.

Frequently Asked Questions

Can I generate QR codes in bulk too?

Yes, the same studio has a QR category with its own template. This page is for the industrial 2D families that QR readers do not always handle.

Which symbology names does the template accept?

datamatrix, aztec, pdf417, dotcode and microqrcode, in lower case or upper case. Anything the renderer does not recognise is reported as a failed row rather than guessed at.

Is my data uploaded?

No. The file is parsed and every symbol is drawn locally, so part numbers and serial values stay on your machine.

Can I print directly from the export?

The PDF sheet is printable as it is. For label printers, use the PNG files at the size your software expects, or the SVG files when the artwork will be resized.
