LabelCSV

LabelCSV turns a spreadsheet into a print-ready Avery label PDF. Paste a CSV, drop an Excel file, or use a Google Sheets publish-to-web link, then map the name and address columns (or write a template with {column} tokens), preview the sheet and download the PDF. It covers 10 US Letter templates including Avery 5160, 5161, 5163, 5167 and 22805, with a start-at-label option and a printer nudge. Everything runs in your browser, so your address list is never uploaded and there is no Google permission prompt. Free PDFs include one sheet, then it's $19 for 50 credits or $9/mo unlimited.
