Replacing a word everywhere without touching the same letters inside other words needs exact boundaries.
Word Replacer swaps a word only where it stands alone, leaving longer words that contain it untouched.
How to use Word Replacer
- Paste or type the text with the word to replace into the input box.
- Enter the word to replace and keep Whole word on so only standalone words are changed.
- Copy the result with each exact word match replaced.
Use cases
- Replacing a term without affecting longer words that contain it.
- Swapping a standalone word consistently across text.
- Changing a word while leaving compounds and substrings alone.
Good to know
Word Replacer uses word boundaries so it changes a word only when it appears on its own, not as part of a larger word. Case sensitivity is optional, and inputs above about 200,000 characters wait for a Run replacement click so the page stays responsive.
Frequently asked questions
How is this different from a plain replace?
It matches whole words only, so replacing in leaves inside and within untouched, which a plain replace would change.
Can I make the match case-sensitive?
Yes. Turn on case sensitivity to change only exact-case words, or leave it off to match every capitalisation.
Does a large paste still run instantly?
Above roughly 200,000 characters the result waits for a Run replacement click, which keeps the page responsive.
