How does online find and replace work?

Enter the text to find and its replacement; every occurrence in your pasted text is replaced at once, with a count of replacements made. Options control case sensitivity and whole-word matching.

What does whole-word matching do?

It prevents partial hits: replacing 'cat' with 'dog' in whole-word mode leaves 'category' untouched. Without it, you'd get 'dogegory' — the classic find-replace disaster.

Can I use regular expressions?

Yes — regex mode enables pattern replacements like normalizing all dates from MM/DD/YYYY to YYYY-MM-DD using capture groups ($1, $2) in the replacement.

Can I do multiple different replacements at once?

Yes — add several find→replace pairs and run them in sequence in a single pass, useful for cleanup recipes you apply repeatedly.

Completely — all replacement happens in your browser. Documents are never uploaded.

Find and Replace Text — Bulk Edits Without Opening an Editor

Renaming a product across a document, fixing a repeated typo, normalizing date formats, cleaning exported data — find-and-replace is the workhorse of text editing, and doing it in a browser beats pasting into a word processor. This free tool replaces every occurrence instantly with case control, whole-word safety, regex power, and multi-pair batch mode. Local processing, no signup.

The Whole-Word Safety Net

Naive replacement is dangerous: swap "man" → "person" and you get "personage" from "manage" and "Gerpersony" from "Germany". Whole-word mode bounds matches at word edges, making bulk renames safe. It's the option to enable by default whenever your find-term could live inside longer words.

Regex Mode: Replacement Superpowers

Reformat dates:   find (\d{2})/(\d{2})/(\d{4})  →  replace $3-$1-$2
Strip prices:     find \$[\d,]+\.\d{2}          →  replace [PRICE]
Collapse spaces:  find  +                        →  replace (one space)
Kill trailing ws: find \s+$ (multiline)          →  replace (nothing)

Capture groups let you reorder and reuse matched parts — the technique that turns an hour of manual edits into one operation.

Batch Recipes

Chain multiple pairs for repeatable cleanups: smart quotes → straight quotes, double spaces → single, em-dash variants → one style, old brand name → new. Run the same recipe on every document that crosses your desk — consistency without memory effort.

Free and Private

Unlimited text and replacements, all in-browser — client documents and code never leave your device.
