Text Cleaner

Clean text — collapse whitespace, trim lines, remove invisible characters, fix line endings, normalize quotes. Free, runs in your browser.

Reference

How does the text cleaner work?

This tool runs your text through a configurable pipeline of normalization steps using JavaScript string and regex methods. Each option toggles a discrete transformation: whitespace collapsing uses /\s+/g; invisible character removal uses Unicode property classes; smart-quote replacement uses a Map of curly-to-straight pairs; diacritic stripping uses .normalize('NFD') followed by combining-mark removal.

Common uses

  • Copy-paste cleanup — fix text pulled from PDFs, Word, or web pages.
  • CSV/TSV imports — strip stray whitespace before parsing.
  • Diff prep — normalize files before comparing.
  • Anti-spam — strip invisible Unicode characters that hide phishing payloads.
