LabelPeel

LabelPeel is a browser tool for printing labels straight from a spreadsheet. Copy your rows from Excel, Google Sheets or Numbers, or drop in an .xlsx or CSV file, and every row becomes a label. Pick your sheet by typing the code on the pack: Avery-compatible 5160, L7160 and more than 80 others, in US Letter and A4, plus custom sizes.

You can restyle labels in plain English. Type "make Room A orange" and only the matching labels change. Click any label to fix a typo, turn a column into a barcode or QR code, add a logo, or start on a half-used sheet. A plain-paper test page helps line up your printer.

When you're done, print at actual size or download a PDF. There's no Word mail merge and nothing to install, and it's free while in beta, no card needed. Run from Malta.
