Text Line Tools
Clean up any list — email addresses, file names, IDs, product codes — by deduping, sorting, and counting lines.

Result
Everything runs in your browser — nothing is uploaded.
When to use this
You exported a list from a spreadsheet or tool and it has duplicates, or you need a sorted inventory before batch-renaming files. Paste, clean, copy — no spreadsheet formulas needed. The same output feeds the Batch Rename Fixer when your list becomes a rename plan.
Worked example
Your download folder export has IMG_2024.jpg listed twice (once as .jpg, once as .JPG). With “ignore case” on, dedupe keeps one line; sorting A→Z groups all IMG_ entries together so you can review before a batch rename.
Boundaries
Numeric sort works on leading numbers of each line; for mixed text it falls back to 0. Dedupe is exact-match (or case-insensitive exact-match) — lines that differ by a space or punctuation are treated as different.
FAQ
Is my text uploaded? No — all processing happens in your browser.
Can I process very large lists? Thousands of lines work fine; for huge exports your browser’s textarea is the practical limit.
