Find & Replace
Multi-rule find and replace with regex support, case control and whole-word matching.
What is Find & Replace?
Find & Replace is a powerful text editing utility that lets you search for specific words, phrases, or patterns within a block of text and replace them with something else. Unlike a simple single-rule editor, this tool supports multiple replacement rules applied in sequence, giving you full control over batch text transformations.
You can choose to match text exactly as typed, or enable case-insensitive mode to catch all variations regardless of capitalization. The whole-word option ensures you only replace standalone words, preventing partial matches inside longer words. For advanced users, regular expression (regex) mode unlocks pattern-based matching, letting you replace anything from simple strings to complex structured patterns.
This tool is ideal for preparing content for publication, cleaning up exported data, normalizing inconsistent formatting, or doing bulk renaming tasks on text-based content. Developers use it to sanitize data, writers use it to fix repeated errors, and content managers use it to update terminology across entire documents. Because everything runs in your browser, your text stays completely private with no server uploads required.
How to Use Find & Replace
- Paste your source text
Enter or paste the text you want to modify into the input area. Any length of text is supported.
- Add replacement rules
Define one or more find-and-replace pairs. Enable regex, case sensitivity, or whole-word matching per rule.
- Apply rules
Click Apply to run all rules in order against your text. Preview the result before committing changes.
- Copy the result
Copy the transformed text to your clipboard or download it as a plain text file.
Key Benefits
Stack several find-and-replace pairs and apply them all in a single pass for efficient batch editing.
Switch between exact, case-insensitive, whole-word, or full regex matching to suit your specific needs.
See results update instantly so you can confirm your rules are working before copying the output.
All replacements happen entirely in your browser — your text is never sent to any external server.
Frequently Asked Questions
This tool uses standard JavaScript regular expression syntax. For example, use '\d+' to match numbers, '\s+' for whitespace, and flags like 'i' for case-insensitive matching.
Yes, rules are applied top to bottom in the order you add them. The output of one rule becomes the input for the next, so rule order matters for overlapping patterns.
Yes. In regex mode, use '\n' for newlines and '\t' for tabs. You can replace them with spaces or any other character to normalize whitespace.
There is no hard limit. You can add as many rules as needed. For very long texts with many rules, processing may take a moment but remains fully in-browser.
