Sheetwise Label Maker

Use this when the user wants to check or clean a mailing list or contact list before printing labels ("turn my contact list into mailing labels", "address labels from excel spreadsheet", "clean up my address list"): reads an uploaded CSV/XLSX file or a typed list, shows which columns were used for name, street, city, state and ZIP, formats each address the USPS way, and reports missing streets, cities, states, ZIP codes, unknown state codes and duplicates, with a cleaned CSV download. Does not verify that an address exists, does not look up ZIP+4, and does not print the labels (use generate_label_sheet).

Use this when the user asks which label sheet to use or what the measurements of a sheet are ("avery 5160 size", "avery 5160 label size", "30 labels per sheet template", "1 x 2-5/8 labels", "name badge label size", "which labels for return address"). Searches the supported US Letter label sheets by product number, label size, labels per sheet or use, and returns the layout: label size, columns and rows, top/side margins, pitch and products with the same layout. Does not print labels (use generate_label_sheet) and does not cover A4 sheets or label-maker tape.

Use this when the user wants to print address labels, mailing labels, return address labels, shipping labels, name badges or name tags, place cards, or file folder labels from a list or a spreadsheet ("avery 5160 template", "print address labels from excel", "mailing labels from excel", "make return address labels", "print christmas card addresses on labels", "start printing at label 7 on a used sheet"). Builds a vector PDF on US Letter that lines up with the chosen label sheet (5160/8160 30 per sheet, 5161, 5162, 5163, 5164, 5168, 5126, 5167, 5195, 5366, 5395, 5390, 22805, 5302 place cards), with USPS address lines, font shrink-to-fit, a start position for partly used sheets, copies per label, return-address fill mode, an optional alignment test page and outlines. Accepts typed labels or an uploaded CSV/XLSX file. Returns a preview, the PDF and a cleaned CSV. Does not buy postage, print USPS shipping labels with postage, make barcodes, or design nutrition labels.
