Find and Replace Text Online
Enter a search term and a replacement, then apply it to your entire text at once. Supports case-sensitive matching and whole-word boundaries so you can replace exactly what you intend without touching similar words. Useful for renaming variables in drafts, fixing repeated typos, updating placeholders in templates, and bulk editing any plain-text content.
How to Use Find and Replace
- 1Enter the word or phrase you want to find in the Find field
- 2Enter the replacement text (leave empty to simply delete the matched text)
- 3Toggle case sensitivity or whole-word matching if needed
- 4Paste your text in the input area and click Replace All
Key Benefits
- Replaces all occurrences in one action
- Case-sensitive and whole-word options prevent unintended matches
- Shows match count before and after replacement
- Leave replacement field empty to delete all occurrences
Frequently Asked Questions
What does 'whole word only' mean?
With whole-word matching enabled, the tool only replaces the search term when it appears as a standalone word — surrounded by spaces, punctuation, or the start/end of a line. For example, searching for 'cat' would match the word 'cat' in 'my cat sat' but not the substring 'cat' in 'concatenate'. This prevents unintended replacements inside longer words.
Can I delete all occurrences of a word?
Yes. Leave the Replace with field completely empty and click Replace All. Every instance of the search term will be removed from the text. This is useful for stripping repeated filler words, placeholder tokens, or unwanted tags from a document.
Does this support regular expressions?
The current version uses plain-text matching with optional case sensitivity and whole-word boundaries — it does not support custom regular expressions in the find field. The search term is automatically escaped so special characters like a period or asterisk are treated as literal characters, not regex operators. For regex-based replacements, a code editor or terminal is more appropriate.
How does case-sensitive matching work?
When case sensitivity is off (the default), 'Hello', 'hello', and 'HELLO' all match and get replaced. When case sensitivity is on, only exact-case matches are replaced — searching for 'Hello' will not touch 'hello' or 'HELLO'. Use case-sensitive mode when you need to distinguish between proper nouns and common words, or when replacing identifiers in code drafts.
What happens if the find field is empty?
The Replace All button is disabled when the find field is empty. An empty search pattern would match every position in the text, producing unpredictable results. Enter at least one character before replacing.
Can I use this for template placeholder substitution?
Yes. A common workflow is to write a template with placeholder tokens — for example, using something like FIRSTNAME or NAME_HERE — and then use this tool to replace each placeholder with actual content. Each placeholder replacement is one find-and-replace pass. For multiple different placeholders, run the tool once per placeholder, copying the output back to the input each time.
