How to Use

Follow these simple steps to master text replacement and unlock the full potential of our advanced features.

1
Enter Your Text
Paste or type your text into the input textarea. The tool can handle large amounts of text efficiently. Character count is displayed in real-time.
2
Set Find & Replace Values
Enter the text you want to find in the "Text to Find" field, and the replacement text in the "Replacement Text" field. Leave replacement empty to delete matches.
3
Configure Options
Choose your search options: Case Sensitive for exact case matching, Whole Words Only to match complete words, Use Regular Expressions for pattern matching, and Replace All to replace every occurrence.
4
Process Your Text
Click "Replace Text" to perform the replacement, or "Count Matches" to see how many matches exist without making changes. Results appear instantly in the output area.
5
Copy or Continue
Use "Copy Result" to copy the processed text to your clipboard. Use "Swap Input/Output" to use the result as input for further processing. "Clear All" resets everything.
💡 Pro Tips for Advanced Usage
Regular Expressions: Use patterns like \d+ to find numbers, \w+@\w+\.\w+ for emails, or ^\s*$ for empty lines.

Whole Word Matching: When enabled, "cat" won't match "catalog" or "scattered" - only standalone "cat".

Case Sensitivity: Disable for flexible matching where "Hello", "HELLO", and "hello" are treated the same.

Batch Processing: Use "Swap Input/Output" to chain multiple replacements for complex text transformations.

Frequently Asked Questions

What makes this text replacement tool “advanced”?

It supports regex patterns, case/whole-word matching, real-time stats, match counting, and input/output swapping — perfect for developers, writers, and data cleaners who need precision and power.

Is my text sent to a server?

No. All find/replace operations happen 100% in your browser. Your text never leaves your device — no tracking, no storage, no third-party access. Fully private and secure.

Do I need to install or register?

Nothing to install or register. Just open the page in any browser — desktop or mobile — and start replacing instantly. No login, no ads, no paywalls.

How do I use Regular Expressions?

Check “Use Regular Expressions” and enter patterns like \d+ (numbers), ^\s*$ (empty lines), or [A-Z]{3} (3 uppercase letters). Enables powerful, flexible text processing.

What’s the difference between “Whole Words Only” and “Case Sensitive”?

Whole Words Only: “cat” won’t match “category”. Case Sensitive: “Apple” ≠ “apple”. Use together for surgical precision — or disable both for broad, flexible matching.

Can I delete text instead of replacing it?

Yes. Leave the “Replacement Text” field empty — all matches will be removed. Great for cleaning up unwanted words, tags, or placeholders.

What does “Swap Input/Output” do?

Instantly moves your output back to input — perfect for chaining multiple replacements (e.g., clean → format → finalize) without copy-pasting. Enables complex text transformation workflows.

Can I process very large text (1M+ characters)?

Yes — optimized for speed and memory. Handles novels, logs, codebases, or datasets with ease. Stats update in real-time so you always know what’s happening.

Does it work offline?

Yes. Once loaded, all features work without internet. Ideal for secure environments or when editing sensitive documents locally.

Who should use this tool?

Developers (code refactoring), writers (editing), analysts (data cleaning), admins (log processing), students — anyone who needs precise, powerful text manipulation. Personal or commercial use.

Can I use this commercially?

Yes. Free for any use — no license or attribution required. Many teams use it for content migration, data sanitization, report generation, or automated text processing.

How do I report bugs or request features?
