What this tool does

A single place for every quick text-cleaning operation you'd otherwise use Excel, Notepad++, or a scripting language for — removing duplicates, stripping blank lines, sorting, shuffling, wrapping lines in quotes, adding bullets, joining as CSV, find-and-replace with regex, and more. All 20+ operations run instantly in your browser.

Common workflows

  • Deduplicate a mailing list — paste email addresses, click "Duplicate lines", then copy the cleaned output.
  • Clean up a list pasted from a PDF — "Trim each line" + "Remove empty lines" + "Remove extra spaces" fixes most formatting damage.
  • Wrap items for SQL / JS arrays — "Wrap each in quotes" + "Join as CSV" turns a list into "apple", "banana", "cherry".
  • Remove line breaks from copied text — essential when pasting body text copied from a PDF that's line-wrapped.
  • Turn a list into HTML — prefix <li> and suffix </li>, then wrap manually.
  • Find common entries — "Count duplicates" sorts by frequency, handy for log analysis.

Regex tips for find-and-replace

  • \d+ — any run of digits. \s+ — any run of whitespace.
  • ^ — start of a line, $ — end of a line (with m flag behaviour in most engines).
  • Backreferences: find (\w+)\s(\w+), replace with $2 $1 to swap word pairs.
  • Use \b for word boundaries: \bcat\b matches "cat" but not "category".

Tips

  • Use "Use as new input" to chain operations — e.g. dedupe, then sort, then add bullets.
  • Everything runs locally. Nothing is uploaded or logged.
  • The input/output stats show line and character counts so you can verify what changed.
