Label / Business-Card Batch Generator

Turn a CSV of names and addresses into a print-ready Avery label or business-card sheet — right in your browser, nothing uploaded.

What it does

What it does. You paste or upload a CSV — names, street addresses, whatever columns your spreadsheet already has — and the tool maps each column onto a line of a label or business card. Pick Avery 5160 (address labels, 30 per sheet) or Avery 8371/8871 (business cards, 10 per sheet), watch a live preview build itself in the exact real-world grid, and print. Rows that don't fit on one sheet continue automatically onto more sheets — there's no per-batch limit built into the tool. Who it's for. A small business owner who has a spreadsheet of client addresses and needs 60 holiday cards mailed by Friday, and doesn't want to fight Word's mail-merge wizard or hand a customer list to a hosted web app to get there. Example scenario. A cafe owner exports her loyalty-club sign-up list from her point-of-sale system as a CSV — name, street, city, state, zip. She opens this tool, drags the file in, confirms the auto-guessed column mapping (it correctly spotted "street" and "city_state_zip" without being told), picks Avery 5160, and gets a print preview showing exactly how the 30-label sheet will come out of her printer. She prints two sheets for 47 customers and is done in under two minutes. What it explicitly does not do:

• It does not verify that an address is real or deliverable — it only lays

out whatever text you give it onto the label grid (same honest scope as

the sibling Address/Phone Formatter tool).

• It does not support A4 label sheets — only US Letter (8.5″×11″)

Avery-compatible SKUs, since that's what the two supported presets are

actually spec'd for.

• It does not read an existing Word mail-merge template — it has its own

simple column→line mapping instead (see the FAQ for why).

• It does not do barcodes, QR codes, or general-purpose label design (shelf

labels, shipping labels, product labels) — just names/addresses onto

address-label or business-card sheets.

Features

• Real, sourced Avery dimensions — Avery 5160 (1″×2⅝″, 30/sheet, 3×10 grid)

and Avery 8371/8871 (2″×3½″, 10/sheet, 2×5 grid), grid pitch verified to

the inch against the published spec using a generated PDF, not eyeballed

• Auto-guesses which CSV column is the name vs. street vs. city/state/zip

from the header text, with a mapping table you confirm or change before

anything renders

• Live preview is the exact same DOM and CSS that prints — not a separate

mockup — so what you see on screen is what comes out of the printer

• Automatically shrinks text to fit a label, and only truncates (with a

visible "…" and an on-screen flagged-rows list) when content genuinely

can't fit even at the smallest readable size

• Handles CSVs larger than one sheet by paginating automatically across as

many sheets as needed — tested with 220 rows across 8 sheets in under

half a second

• Zero network requests: no upload, no account, no server — the CSV never

leaves your browser tab

Browser support

Verified by generating real print output and reading it back programmatically (via `pypdf`/`pymupdf`), not by inspection, and by loading the tool in each engine and checking for console errors: Known cross-engine subtlety, found and handled: in real testing, Chromium's print/PDF rasterizer measured text a hair wider than the on-screen layout pass measured the same font at the same size. Left alone, that gap could make a label that measured "fits" on screen come out ellipsis-truncated in the actual printed PDF. The text-fit logic now shrinks to a font size with a small deliberate safety margin below the true fit point specifically to absorb this — confirmed fixed by generating an actual PDF and reading its text back with `pymupdf` (zero unexpected truncations across a 28-row and a 220-row test run).

FAQ

Does this upload my recipient list anywhere?
No. The tool makes zero network requests — everything is parsed and laid
out in your browser tab. Reload the page and everything you loaded is gone
from memory. This was checked directly (no `fetch`/`XHR`/`` calls
anywhere in the file) and is the main reason this exists instead of using
a hosted "free" label-maker web app.

Which label sheets are supported?
Avery 5160 address labels (1″×2⅝″, 30 per sheet) and Avery 8371/8871
business cards (2″×3½″, 10 per sheet) — both US Letter (8.5″×11″). A4 label
sheets use different dimensions entirely and aren't supported in this
version.

What happens to my file if I lose the download?
There's no license key or activation to lose — the tool is a single HTML
file. Re-download it from your original purchase/order confirmation at any
time; there's nothing else to track.

Does this work with a Word mail-merge template I already have?
No — this doesn't read `.docx` mail-merge templates. It has its own simple
column-to-line mapping instead. If you already have a working Word mail
merge set up and it isn't causing you problems, there's no reason to
switch; this tool is for people who'd rather not deal with the Mail Merge
Wizard in the first place, or who don't want their spreadsheet touching a
hosted "free" web tool.

Does this work on my iPhone/iPad?
Not tested. No iOS device was available to verify this on, so no claim is
made either way — assume desktop only until that's checked.

Can I use this for client or commercial work?
Yes — see the license below.

Is there a subscription?
No. One-time purchase, use it as long as you like.
