Duplicate Line Remover guide
Strip repeated lines from pasted text with optional sorting and trim — no upload, developer-friendly defaults.
Open toolPrivacy
For supported workflows, files are processed locally in your browser and are not uploaded to SnapTools servers.
Overview
Collapse repeated lines from logs, CSV dumps, and checklists while keeping order (or sort alphabetically) — processing stays on-device.
Pair with JSON Formatter when you are tightening machine-readable payloads.
How it works
Lines split on newline boundaries, optional trimming and sorting run, then a Set removes duplicates while optionally preserving first-seen order.
Benefits
Shrink noisy logs, dedupe customer exports, and prep CSV snippets before diffing or ticketing.
Security & privacy
Because everything stays client-side, you can paste regulated lists when policy allows — still clear the textarea afterward.
