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

Get answers to common questions about using our text replacement tool and troubleshooting tips.

Is my text data secure and private? +
Absolutely! All text processing happens entirely in your browser. Your data never leaves your device or gets sent to any servers. This ensures complete privacy and security for sensitive documents.
What's the maximum text size I can process? +
The tool can handle very large texts (1M+ characters) efficiently. The actual limit depends on your device's memory, but most documents and even large datasets process without issues.
How do I use regular expressions? +
Check the "Use Regular Expressions" option and enter regex patterns in the find field. Common examples: \d+ (numbers), \w+ (words), ^.* (lines starting with anything), \s+ (whitespace). Remember to escape special characters if you want to match them literally.
Can I undo a replacement operation? +
The original text remains in the input field, so you can always refer back to it. For complex operations, consider using "Count Matches" first to preview results before replacing. You can also use "Swap Input/Output" to move results back to input for further processing.
What does "Whole Words Only" do? +
This option ensures matches occur only at word boundaries. For example, searching for "cat" with this option won't match "catalog" or "scattered" - only standalone "cat" surrounded by spaces, punctuation, or line breaks.
Does the tool work offline? +
Yes! Once the page loads, all functionality works offline. The tool runs entirely in your browser using JavaScript, so you don't need an internet connection to process text.
Can I replace with empty text to delete matches? +
Absolutely! Leave the "Replacement Text" field empty to delete all matches. This is useful for removing unwanted characters, extra spaces, or entire words/phrases from your text.
Why use this over simple Ctrl+H find and replace? +
Our tool offers advanced features like regex support, real-time statistics, match counting before replacement, and the ability to process large texts that might slow down text editors. Plus, it works in any browser without installing software.
Are there keyboard shortcuts available? +
Standard browser shortcuts work: Ctrl+A to select all text, Ctrl+C to copy, Ctrl+V to paste. For the tool buttons, you can use Tab to navigate and Enter to activate. The interface is fully keyboard accessible.
Can I suggest new features or report bugs? +
