How to use Replace Words in Text
- 1. Paste the text you want to update. Enter the passage containing the word you need to change everywhere it appears, such as a document mentioning an old term throughout.
- 2. Enter Find and Replace with. Type the word to search for in Find and the word it should become in Replace with, such as swapping an old brand name for its current one.
- 3. Set Whole words only and Match case. Turn on Whole words only to avoid replacing the search term inside longer words, like matching 'cat' but not 'category', and turn on Match case to respect capitalization exactly.
- 4. Copy the updated text. Copy the result with every matching occurrence swapped, ready for your document, message, or codebase update.
When to use Replace Words in Text
Replace Words in Text substitutes one word for another everywhere it appears, with options to respect whole-word boundaries and capitalization so the swap doesn't catch unintended matches. Use Replace Words in Text whenever a term across a document needs a consistent, one-time update.
- Updating a rebranded product name throughout copy. A company renamed a product and every mention of the old name across marketing copy needs to become the new one. Whole words only prevents accidentally matching the old name inside unrelated compound words.
- Correcting a consistently misspelled term in a draft. A writer kept misspelling a specific technical term the same way throughout a long document. Replacing that exact misspelling everywhere fixes it in one pass instead of manual find-and-fix.
- Swapping a placeholder variable name in sample code. A code example uses a generic placeholder like 'foo' that needs to become a meaningful variable name before publishing as documentation. Whole words only avoids touching 'foobar' if it also appears.
- Standardizing terminology across a style guide update. A style guide changed the preferred term for a concept, and existing documentation still uses the old wording. Replacing it with case matching preserves any sentence-starting capitalization correctly.
Examples
Replace cats with dogs
Input
I like cats. Cats are great.
Output
I like dogs. dogs are great.

Frequently asked questions
Is Replace Words in Text free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
