Find and Replace Tool

What is a Find and Replace Tool?

A find and replace tool searches your text for a word, phrase, or pattern and replaces every match with something new. It is the fastest way to make consistent edits across a large block of text without changing each occurrence by hand — turning a tedious, error-prone task into a single click. Whether you need to swap one product name for another across a document or reformat hundreds of lines at once, find and replace does the work instantly.

Our online Find and Replace Tool supports simple plain-text search as well as advanced options: toggle case sensitivity, restrict matches to whole words, or enable full regular expression (regex) support for powerful pattern-based replacements. A live counter shows exactly how many matches were found, so you always know the scope of a change before and after you make it. Everything runs in your browser with no signup required.

How to Find and Replace Text

• Paste or type your text into the input box
• Enter the word, phrase, or pattern you want to find
• Enter the replacement text (leave it empty to simply delete the matches)
• Optionally enable case-sensitive matching, whole-word matching, or regular expressions
• Watch the live match count, then copy the updated text in one click

Key Features

• Case-sensitive or case-insensitive matching for precise control
• Whole-word matching to avoid replacing parts of longer words
• Full regular expression support for advanced search-and-replace patterns
• Live match count so you can see how many replacements will be made
• Replace-all in a single action across the entire text
• 100% browser-based — your text never leaves your device, ensuring complete privacy

Using Regular Expressions

Regular expressions (regex) unlock pattern-based replacements that plain text search cannot handle. With regex enabled you can match variable patterns — such as all numbers, all email addresses, repeated whitespace, or text between specific characters — and replace them in one pass. Capture groups let you reuse parts of each match in the replacement, which is ideal for reformatting dates, phone numbers, or names.

For example, you can collapse multiple spaces into one, strip trailing punctuation, reorder 'First Last' into 'Last, First', or wrap every matched term in brackets. If you are new to regex, start with simple patterns and use the live match count to confirm you are matching exactly what you intend before replacing.

Why Choose Our Find and Replace Tool?

This tool is completely free, needs no account, and processes everything locally in your browser. Because your text is never uploaded to a server, you can safely run find and replace on confidential documents, source code, exported data, and private notes — nothing is logged or stored anywhere. That makes it a trustworthy choice for sensitive work that you would never want to paste into an unknown online service.

Find and Replace is one of more than 200 free tools on ToopTools. If you clean up or reformat text regularly, you can pin it to your personalized My Workspace workspace so it stays right next to your other favourite utilities, ready in a single click. The tool works on any modern browser, on desktop and mobile alike.

Common Use Cases

Writers and editors use find and replace to update terminology consistently across a long document — changing a character's name, swapping British spellings for American, or correcting a repeated mistake everywhere at once. Developers use it to rename variables, update import paths, and reformat data without opening an editor.

Data workers use it to clean exported spreadsheets and logs — removing unwanted characters, normalizing delimiters, or stripping prefixes from thousands of rows. Marketers and SEO professionals use it to bulk-edit lists of keywords, URLs, and tags. Anyone who works with text regularly will save significant time by replacing dozens or hundreds of occurrences in one action.

Plain Text vs Regex: Which to Use

For most everyday edits, plain-text find and replace is all you need: you type the exact word or phrase to find, type what should take its place, and every match is swapped. Turning on case-sensitive matching lets you distinguish 'Apple' from 'apple', and whole-word matching prevents a search for 'art' from accidentally changing 'start' or 'smart'. These two options alone make plain-text replacement precise enough for the vast majority of tasks.

Regular expressions come into play when what you want to match follows a pattern rather than a fixed string. Instead of one literal phrase, regex lets you target 'any sequence of digits', 'any email address', 'two or more spaces in a row', or 'text between brackets'. With capture groups you can even reuse parts of each match in the replacement, which is how you reformat dates, swap name order, or wrap matched terms in new text — all in a single pass.

A good rule of thumb is to start with plain text and only reach for regex when the pattern varies. When you do use regex, the live match count is your safety net: adjust your pattern and watch the number of matches until it reflects exactly what you intend to change, then perform the replacement with confidence. This keeps powerful pattern editing safe and predictable, even on large blocks of text.

Is the Find and Replace Tool free?

Yes. It is 100% free with no limits and no signup. You can find and replace text in as many documents as you like, as often as you like, without creating an account.

Does it support regular expressions?

Yes. You can enable full regular expression support to match complex patterns, use capture groups, and perform advanced replacements that plain-text search cannot achieve.

Is my text kept private?

Completely. All searching and replacing happens in your browser, so your text is never uploaded, logged, or stored on any server. It is safe to use with confidential or sensitive content.

Can I delete text instead of replacing it?

Yes. Leave the replacement field empty and every match will be removed from your text, which is a quick way to strip out unwanted words, characters, or patterns in bulk.

What is whole-word matching?

Whole-word matching ensures that only complete words are replaced. For example, searching for 'cat' with whole-word matching on will not change 'category' or 'concatenate', so you avoid accidental replacements inside longer words.

Can I find and replace text in bulk across a whole document?

Yes. The tool replaces every match in one action, so you can update a word or phrase across an entire document or list at once. With case-sensitive, whole-word, and regex options, you can make precise bulk edits to thousands of lines instantly.

Does the find and replace tool work offline?

Yes. All searching and replacing happens in your browser, so once the page has loaded it works without an internet connection. Your text is never uploaded, which makes it safe to run bulk replacements on confidential documents, code, and exported data.
