FREE — Stable Line Deduplicator

Try a complete utility free: remove repeated lines while keeping their first-occurrence order.

WORKED EXAMPLE

Input, one item per line: apple / pear / apple. With exact matching and trimming off, the retained lines are apple / pear. Try the included synthetic example, then paste your own list and download the JSON result.

Unzip text-01.zip and open text-01.html in your browser. Includes the HTML utility, instructions, privacy notes and a single-user license for personal and commercial work. No subscription or telemetry in the utility. Payhip handles checkout and delivery separately.

Limits: 80,000 UTF-16 text units and 1,000 lines/items; 200,000-character interface input limit. Exact matching by default; optional trimming changes comparison and output. Downloads include your input and results.

Release candidate: automated logic and simulated-interface checks passed; graphical browser compatibility remains unverified.
