Clean text instantly with Centrigon’s duplicate line remover.
Invisible spaces, mixed case, or blank lines often break deduplication. Trim whitespace and case‑sensitive toggles let you catch what the eye misses.
Keep first occurrence preserves the original sequence — ideal for logs or historical lists. Sorting gives you alphabetical clarity when order doesn't matter.
Combine both: uncheck "keep first occurrence" and pick A→Z to generate clean sorted lists from messy data.
