Quick Examples
What is Find and Replace?
Find and Replace is a powerful text manipulation function that allows you to search for specific text patterns and replace them with different content. This tool is essential for editing documents, cleaning data, updating code, and performing bulk text transformations efficiently.
Our online Find and Replace tool provides advanced features including case-sensitive matching, whole word search, and regular expression support, making it suitable for both simple text replacements and complex pattern matching tasks.
Common Use Cases
Document Editing
Update names, terms, or phrases throughout large documents without manual editing
Code Refactoring
Rename variables, update function names, or modify code patterns across files
Data Cleaning
Remove unwanted characters, fix formatting, or standardize data entries
Content Updates
Update URLs, email addresses, phone numbers, or any repeated content in bulk
Features Explained
Case Sensitive
When enabled, the search distinguishes between uppercase and lowercase letters. For example, searching for "Apple" will not match "apple" or "APPLE". This is useful when you need precise matching of proper nouns or specific formatting.
Whole Word
Matches only complete words, not partial matches within larger words. For example, searching for "cat" will match "cat" but not "category" or "concatenate". This prevents unwanted replacements in compound words.
Regular Expression (Regex)
Enables pattern matching using regular expressions for advanced search capabilities.
You can match multiple patterns, specific character types, or complex text structures.
For example, \d3-\d4 matches phone numbers
like "555-1234".
