Find and Replace Text

Bulk Find and Replace, Applied in Order

Paste a block of text, stack as many find-and-replace rules as you need, and watch the result update live. Rules run top to bottom — rule two operates on the output of rule one — so you can build a small cleanup pipeline instead of running a dozen replacements by hand. Each rule shows its own match count, so you always know exactly what changed.

Every rule carries four flags: case-insensitive, whole-word, regex, and replace-all. In regex mode you get full JavaScript regular expressions with $1/$2 backreferences in the replacement; in plain mode your find text and replacement are treated literally, so a "." only matches a period and a "$5.00" replacement inserts verbatim. An invalid regex is caught on its own rule and skipped, with the error shown inline — it never blocks the rest of the pipeline.

Because it runs entirely in your browser, there is no upload, no sign-up, and no limit on how much text you push through it. The honest caveat: this transforms plain text, not formatting — paste from a Word doc and you get the words, not the bold and italics. Regex here is JavaScript-flavored, so a pattern copied from a Perl or PCRE tool may need small tweaks.

• Terminology sweeps: Normalize a document to a style guide — swap "e-mail" for "email", "web site" for "website", and a product's old name for its new one, all in one pass.
• Data cleanup: Strip stray characters, collapse whitespace, or fix delimiters in exported CSV/log text before you paste it somewhere that matters.
• Code refactors: Rename a variable or string across a pasted snippet with whole-word matching so "id" doesn't clobber "width" or "video".
• Regex reformatting: Reorder "First Last" to "Last, First" or restructure dates with capture groups like $2/$1.
• Templating: Fill placeholders such as {{name}} or [DATE] with real values to turn a boilerplate into a finished message.
• Chained transforms: Layer several rules — decode, then trim, then relabel — and reorder them until the output is exactly right.
