Find and replace text online (with optional regex)

Find and replace is the fastest way to clean a messy paste: swap smart quotes, rename a product across a draft, or strip a repeated phrase. This page supports plain text matching and optional regular expressions, all in your browser. Use it before you publish documentation, before you import CSV into another tool, or when AI output leaves the same filler sentence everywhere.

Plain text vs regular expressions

Plain find/replace is safest for product names and fixed phrases. Regex is powerful for patterns—extra spaces, phone formats, or HTML tags—but a small typo can wipe more than you intended. Test on a short sample first. Escape special characters like `.` `*` `(` when you mean them literally in regex mode.

Common cleanup jobs

Replace curly quotes with straight quotes for code samples. Collapse double spaces after a paste from PDF. Swap an old brand name for a new one across a help center article. Remove tracking parameters from a list of URLs. For line-level deduplication, use Duplicate Line Remover. For overused vocabulary, use Duplicate Word Finder or Word Frequency.
