DEDICATED TOOL PAGE

Remove duplicate lines while keeping original order.

Paste one item per line and keep the first non-empty occurrence of each line. This is useful for copied tags, names, inventory entries, keyword lists and exported rows that repeat.

LIST TOOLS

Run the tool

This page is best when the source list is already roughly one item per line and you want a fast cleanup pass before export or review.

PRACTICAL WORKFLOW

Deduplicate after normalizing the input.

Trim formatting noise first

Extra spaces and inconsistent case can hide true duplicates. Clean those issues first when you know they are accidental.

Preserve order when it matters

This tool keeps the first occurrence so the original sequence remains intact, which helps when order carries meaning.

Review edge cases manually

Near-duplicate rows with dates, IDs or punctuation differences may still describe different records. Treat the result as a strong first pass, not a substitute for judgment.

Common questions

Does it keep empty lines?

No. Empty lines are removed as noise so the output is a clean list of real items.

What if I want case-insensitive duplicate removal?

Normalize case before deduplication if uppercase and lowercase versions should count as the same item.
