- What CSV format does this tool accept?
- Any CSV with at least three columns: product name, price, and SKU or barcode number. The first row should be a header row. Delimiters are auto-detected — commas, semicolons, and tabs all work. UTF-8 encoding is recommended for special characters (e.g. accented letters, currency symbols). If your spreadsheet software exports with a BOM, that is handled automatically.
- What is the difference between Code 128 and QR code for price tags?
- Code 128 is a 1D linear barcode that most retail POS scanners (laser and CCD) can read quickly. It encodes alphanumeric SKUs up to about 48 characters efficiently. QR code is a 2D matrix barcode readable by smartphones and some modern scanners — it can encode longer values and is useful for direct consumer scanning (e.g. linking to a product page via a URL SKU). For traditional retail checkout, Code 128 is the standard choice.
- How many price tags can I generate at once?
- There is no hard limit enforced by the tool. In practice, PDFs with up to a few thousand labels generate within a few seconds on modern hardware. Very large batches (10,000+ rows) may take 15–30 seconds; the progress bar keeps you informed. If you need to print more than ~5,000 labels, consider splitting your CSV into batches of 1,000–2,000 rows.
- Is my product data safe? Is anything uploaded to a server?
- Nothing is uploaded. The entire pipeline — CSV parsing, barcode rendering, and PDF assembly — runs inside your browser using JavaScript. Your product names, prices, and SKUs never leave your device. This makes the tool safe for confidential pricing data and inventory files.
- What print settings should I use?
- Open the downloaded PDF in your PDF viewer and print at 100% / Actual Size — do not use "Fit to Page" or "Shrink to Printable Area," as that will change label dimensions and make the barcodes mismatch standard label sheets. For best barcode scannability use a laser printer at 300 dpi or higher.
- Can I use this with Avery label sheets?
- Yes. The 2×4 layout (8 labels) matches Avery 8163 and similar half-sheet label formats. The 5×6 layout (30 labels) matches Avery 5160 / 8160 address-label sheets which are commonly repurposed for price tags. Print on plain paper first to verify alignment before committing to label stock.
