How to Bulk Generate QR Codes
Never made a QR code in bulk before? You're in the right place. This tutorial walks through the whole process in plain language, from writing your first list to downloading a folder full of ready-to-print codes.
No coding, no design skills, and no software to install — if you can type into a spreadsheet, you can do this.
Before you start
What you'll need.
- A spreadsheet app — Google Sheets, Excel, or Numbers all work — whatever you already have open is fine.
- A list of what to encode — Website links, phone numbers, Wi-Fi logins — anything you'd normally put in one QR code, just several of them.
- About five minutes — That's really it. No account, no download, no watermark on what you make.
Step by step
From spreadsheet to ZIP, in four easy steps.
01
Write down what you want to encode
A CSV is just a spreadsheet saved in the simplest possible format — think of it as a plain list, one row per QR code you want to make. Here's how to build one:
- Open a new spreadsheet in Google Sheets, Excel, or Numbers.
- In the very first cell (A1), type data — this header row is skipped automatically, so it's just a label.
- Below it, type one thing you want turned into a QR code per row.
- Optional: in the second column, give each row a name. That becomes the downloaded file's name.
| data | filename |
|---|---|
| https://mystore.com | homepage |
| https://mystore.com/menu | menu |
| https://mystore.com/contact | contact |
Once your list is ready, save it as a CSV:
Google Sheets
- File
- Download
- Comma Separated Values (.csv)
Excel
- File
- Save As
- CSV (Comma delimited) (*.csv)
In a hurry? Skip straight to the ready-made starter file below and come back to this later.
02
Choose how your codes should look
On the Bulk generator page, set the style for the whole batch — every code you generate will share it, so it's worth doing before you upload anything.
- Size — how big each code prints. Medium works for most uses; go larger for posters.
- QR color & Background — pick any colors you like. If they're too close to each other, a warning appears — that's your cue that a scanner might struggle to read it.
- Center image / logo — optional. Adds your logo to the middle of every code in the batch.
- Error correction (under Advanced options) — controls how much of the code can be damaged, smudged, or covered by a logo and still scan correctly. Higher settings are more forgiving but look slightly busier. If you're adding a logo, leave this on High — the tool actually does this for you automatically.
- Border style — rounded or sharp corners around the logo.
03
Upload your CSV file
Scroll to the CSV file field and choose the file you just saved. It's read instantly — you'll see a line like “3 rows ready to generate” appear right away.
That number is worth a glance before you continue: if it's higher or lower than you expected, open your CSV back up and look for a stray blank row or an extra comma before generating anything.
04
Generate and download your codes
Click Generate ZIP. Every row is rendered with the style you picked and packed into one file called qr-codes.zip, which downloads straight to your browser's usual downloads folder.
A ZIP is just a folder squeezed into a single file. To open it, double-click it on Mac or Windows — it unpacks into a regular folder full of PNG images, one per row, named however you set them up in step 1. From there, print them, drop them into a document, or upload them anywhere images go.
Try it yourself
Not ready to make your own list yet?
Copy this starter file into a spreadsheet, save it as a CSV, and upload it — you'll have three ready-to-scan QR codes in under a minute.

CSV format reference
What to put in the data column, per type.
Bulk rows are encoded exactly as written — there's no type picker to format them for you. Copy the pattern that matches what you're generating.
Tip: Website and Text rows are plain values, so they need no special formatting. Every other type below has a specific string format the code expects — copy the example, then swap in your own values.
Text
Whatever you want the scanner to read — no formatting needed.

Troubleshooting
Common mistakes, and how to fix them.
- Uploaded an Excel or Numbers file and nothing happenedThe tool only reads .csv files. In Excel, use File → Save As and choose “CSV (Comma delimited)”. In Google Sheets, use File → Download → “Comma Separated Values (.csv)”.
- The row count looks wrongUsually a blank row or a stray comma snuck in. Open the CSV and check that every row you expect has something in the first column.
- A Wi-Fi, vCard, or Event code doesn't scan rightDouble-check the format against the reference table below — a missing semicolon or colon in these types will break the code, since scanners read them as strict fields, not free text.
- Multi-line values (vCard, Event) got mixed into the wrong rowMake sure the cell's line breaks were added with Alt/Option+Enter inside the spreadsheet, not by pasting raw text with actual line breaks — the app needs to know it's all one cell so it quotes it correctly when saving as CSV.
- “That CSV has 501 rows” errorBatches are capped at 500 rows to keep things fast. Split your list into two files and upload them one at a time.
FAQ
Frequently asked questions.
Do I need to know how to code?
No. If you can type into a spreadsheet, you can bulk-generate QR codes — there's no code, formulas, or special software involved.
Can I mix different QR types in one batch — like some links and some Wi-Fi codes?
Yes. Each row is used exactly as written, so one CSV can freely mix a website link, a Wi-Fi code, and a phone number, as long as each row is already written in the format that type needs (see the reference table below).
Is there a limit to how many I can make at once?
Up to 500 rows per CSV file. Need more? Just split your list into a few files and upload them one after another.
Does this cost anything?
No — it's free, with no sign-up and no watermark on your codes.
What if I don't want custom filenames?
Leave the second column out entirely. Each file is automatically named after its own content instead.
My CSV won't upload — what's wrong?
Make sure it's saved as a .csv file (not .xlsx or .numbers) and has at least one row of data below the header row.
