DUPE NUKEM

Welcome to Dupe Nukem

Dupe Nukem is your no-nonsense tool for removing duplicate lines from any list — fast. Whether you're scrubbing data, cleaning up content, or prepping files for upload, this tool strips out the clutter so you can focus on what matters.

How It Works

Just paste your list into the input box above, hit NUKE 'EM, and boom — you've got a clean, deduplicated list in seconds. Want to export your results or keep a copy? Use the built-in copy and download options. It's that simple.

• Case-sensitive filtering: Lowercase and normalize entries to nuke case-based dupes like "Apple" vs. "apple".
• Sorting (coming soon): Automatically sort your deduplicated list alphabetically for cleaner organization.
• Trim formatting: Remove extra spaces or preserve line indentation if needed.

Why Use Dupe Nukem?

Managing lists shouldn't be a pain. Dupe Nukem is built for speed and simplicity — no signup, no server processing, no distractions. It's ideal for:

• Data cleanup: Clean CSV entries, email lists, tags, or URLs before import.
• Content prep: Deduplicate to-do items, keyword lists, or scraped data.
• Efficiency: Stop wasting time manually scanning for duplicates.

Tips for Better Results

• Break massive lists into smaller chunks if your browser starts choking.
• Use copy or download to save a backup before closing the tab.
• Case-insensitive and sort tools are coming soon — stay tuned.
