The easiest way to generate sheets of custom stickers and labels

Tired of struggling with Microsoft Word Mail Merge? Our visual generator lets you auto-fill hundreds of sequential labels instantly.

Perfect for Schools and E-Commerce

Whether you are printing out Exam Seat Numbers for 500 students, creating sequential barcode numbers for your warehouse, or making custom mailing labels, doing it manually takes hours. GASO Studio solves this with a Smart Auto-Fill system built directly into the browser.

Excel-Style Drag to Fill

We built our canvas to feel just like Microsoft Excel. Simply type your starting text (e.g. Row A - Seat 001) into a box, grab the small blue handle in the corner, and drag it across the page. The app's smart engine will automatically extract the numbers and fill the rest of the boxes with Row A - Seat 002, 003, etc.

The Bulk Auto-Fill Wizard

If dragging a mouse across 15 pages sounds tedious, just use our Bulk Generation wizard. Type your prefix, your starting number, and how many labels you need. The generator will instantly create multiple A4 pages mathematically divided perfectly for sticker printing.

Invisible Print Grids

When you use the tool, you will see dashed borders indicating exactly where each sticker is. But when you click "Download PDF", those borders are completely removed. The final PDF only contains your crisp text, perfectly centered, ready to be printed directly onto your physical Avery or custom sticker sheets!
