Find and Replace

A find and replace tool that makes bulk edits to any pasted text, with case-sensitive, whole-word and regex modes — including capture-group replacements like $1 — all running entirely in the browser.

This tool gives you full find-and-replace in the browser: paste any text, say what to find and what to put in its place, and take the result away — with three switches that separate a clean edit from a mangled one. Every editor has find-and-replace, but it's often locked inside a document, limited to one file format, or missing those options that make bulk edits safe.

Whole-word matching is the guard rail most built-in tools lack: replacing "cat" with "dog" naively also turns "category" into "dogegory", while whole-word mode touches only the standalone word. Case sensitivity lets you decide whether "Invoice" and "invoice" are the same target — off by default, since they usually are. And regular-expression mode unlocks pattern-based edits for power users: dates, phone numbers, repeated whitespace, anything describable as a pattern, with capture-group references like $1 available in the replacement so you can reorder rather than merely substitute.

Everyday jobs it handles: updating a company or product name across a long document, normalising phone-number or date formats in an exported list, stripping tracking parameters from a page of URLs, fixing a repeated typo in bulk, or converting delimiters in data too irregular for the CSV tools. In plain-text mode the replacement is inserted literally — no surprise interpretation of special characters. Your text never leaves the browser, making it safe for contracts and customer data. Replace, review the output, copy it back.
