A bulk QR code generator turns a spreadsheet of rows, one per product, location, or contact, into a matching set of QR code images in one pass, instead of filling out the single-code form over and over. You upload a CSV file, tell the tool which column holds what, and it generates a code for every row.
Every code in the batch gets the same size, colors and error correction, so fifty store codes come out as one matching set rather than fifty separate jobs. Each image is named from the name column, which makes it easy to match files to rows afterwards.
A good rule of thumb: if you can already picture the spreadsheet, one row per store, per product, per attendee, you have a bulk QR code job, not a one-off. Export that data as a CSV first, since cleaning it up in a spreadsheet is far easier than fixing a column mapping after the file has already been uploaded.
A type column decides what each row becomes, so one file can hold a mix. Leave it out and every row is treated as a link. These are the eight types and the columns each one needs; any column can be named whatever you like, because you map them after upload.
| Type column says | Columns it needs |
|---|---|
url | A link. Rows without http:// or https:// get one added. |
text | Any text to encode as-is. |
wifi | One column of SSID|password|security, optionally a fourth true for a hidden network. |
vcard | A first or last name at minimum; phone, email and company are optional. |
email | An email address. |
sms or phone | A phone number. Include the country code. |
event | A title and a start date. End date and location are optional. |
Rows are validated as they are parsed, so a row missing something required comes back flagged with the reason rather than producing a code that does not work. Fix that row and re-upload.
Making QR codes one at a time in the standard generator works fine for a handful of codes, but the process does not scale: each code means re-entering the type, the content, and re-downloading the image by hand. A CSV-driven batch turns that same work into a single upload and one export step, which is the only practical approach once you are past roughly a dozen codes with a shared format.
Keep column headers short and predictable: name, url, and type are recognized automatically, which saves a manual mapping step. Wrap any field containing a comma in quotes, since a stray comma inside an unquoted value will split it into two columns. Save the spreadsheet as CSV UTF-8 so accented characters in names survive; the plain CSV option in older versions of Excel can garble them. Includehttps:// in every URL so no row fails validation.
For WiFi entries, use the pipe-separated format SSID|password|security in a single column, where security is WPA, WEP, or nopass. Mixing WiFi and URL rows in the same file is fine as long as each row has a type value telling the generator which format to expect.
Test with a small file first, five or ten rows, before uploading a spreadsheet with hundreds of entries. It is much faster to fix a column-mapping mistake on ten rows than to discover it after generating five hundred codes.
If you only need a handful of codes with heavy customization (logos, colors, specific shapes), the custom QR code design studio gives more control per code than a bulk run does. For single WiFi or contact codes outside of a spreadsheet workflow, see the WiFi QR code generator or the vCard QR code generator.
No. Each code from your CSV is a static image, the same as one made individually. If a link in your spreadsheet changes later, re-run that row and replace that one image.
No. Upload your CSV, map the columns, and download the results. There is no sign up and no row limit tied to an account.
At minimum, a name column to label each code and a data column with the content to encode, such as a URL. The generator auto-detects column headers and lets you map them, so columns can be named however you like as long as the first row has headers.
There is no fixed limit. Start with a file of a few hundred rows to check that your column mapping is right; files with thousands of rows take longer to generate and produce a large ZIP. If a big file stalls, split it into batches of about 500 rows.
Yes. Use a column with pipe-separated values in the format "SSID|password|security", mapped to the WiFi type during the mapping step. Security is WPA, WEP, or nopass for an open network, and case does not matter. A fourth field takes "true" for a network that does not broadcast its name, so "Office|s3cret|WPA|true" covers a hidden one; leave it off otherwise.
After generation finishes, use the export option to download every code as a single ZIP file, or download individual images one at a time if you only need a few.
