About Word Replacer Tool
Find and replace words or phrases in your text with this powerful tool. Perfect for editing documents, cleaning data, correcting errors, or performing bulk text transformations.
Supports case-sensitive matching, whole word matching, and regular expressions for advanced pattern matching. Bulk mode allows multiple find/replace operations at once. All processing happens in your browser for complete privacy.
How does the Word Replacer work?
Enter your text, specify what to find and what to replace it with, then click 'Replace'. The tool will search for all occurrences and replace them according to your settings.
What is 'Whole Word Only'?
When enabled, the tool only matches complete words. For example, finding 'cat' with whole word enabled won't match 'category' or 'concatenate', only the standalone word 'cat'.
How do I use Regular Expressions?
Enable 'Use Regular Expression' to use regex patterns. Examples:
- \d+ (matches numbers)
- \w+ (matches words)
- (cat|dog) (matches 'cat' or 'dog')
- ^Start (matches 'Start' at line beginning)
- End$ (matches 'End' at line end)
What is Bulk Replace?
Bulk Replace allows you to perform multiple find/replace operations at once. Enter pairs in format: 'find → replace', one per line. The tool will process all pairs sequentially.
Can I undo replacements?
The tool doesn't have built-in undo. To be safe, copy your original text before replacing, or use the tool multiple times to test your replacements before committing.
