Preguntas Frecuentes

¿Tienes Preguntas? Tenemos Respuestas

How does the Duplicate Line and Word Remover work?

The tool splits your input by line breaks or words, evaluates unique values according to your casing and whitespace settings, and returns a clean, deduplicated list while optionally preserving original chronological order or sorting alphabetically.

Can I remove duplicate words instead of duplicate lines?

Yes! Toggle the mode from "Duplicate Lines" to "Duplicate Words" to clean word lists, keyword research databases, or tag collections.

What does "Case-Sensitive" mean in deduplication?

When case sensitivity is enabled, "Apple" and "apple" are treated as two distinct items. When disabled, "apple" is recognized as a duplicate of "Apple" and deduplicated.

Can I sort the deduplicated output alphabetically?

Yes. Choose between "Keep Original Order", "Sort A → Z", or "Sort Z → A".

Is my data private when cleaning lists?

Yes, 100%. The deduplication script executes entirely inside your browser memory. No email lists, keywords, or documents are ever uploaded to a server.
