What is Find and Replace?
Find and replace is an essential text editing feature that searches for specific text patterns and replaces them with new text. Our advanced tool supports regular expressions (regex) for complex pattern matching, case-sensitive searches, whole word matching, and both single and global replacements. Perfect for bulk editing, data processing, and text transformation tasks.
Key Features:
- Regular Expressions: Use powerful regex patterns for complex searches
- Case Sensitive Search: Toggle case-sensitive matching on or off
- Whole Word Matching: Match complete words only, avoiding partial matches
- Global Replace: Replace all occurrences or just the first match
- Match Details: See line and column numbers for each match
- Real-time Validation: Instant regex pattern validation with error messages
Common Use Cases:
- Code Refactoring: Rename variables, functions, or update API endpoints across files
- Data Cleaning: Standardize formats, remove unwanted characters, or correct repeated text
- Content Editing: Update links, fix typos, or correct repeated phrases in documents
- Log Processing: Extract specific information or filter log entries using regex
- Text Transformation: Convert between formats or restructure data patterns
- Bulk Editing: Make consistent changes across large amounts of text efficiently
