What is the Find and Replace Tool?
The Find and Replace tool allows you to search for specific text patterns and replace them with new content. Whether you need to fix typos, update terminology, or make bulk text changes, this tool makes it quick and easy.
Advanced features include case-sensitive matching, whole word search, regular expression support, and preserve case replacement. Regular expressions enable powerful pattern matching for complex find-and-replace operations.
All processing happens directly in your browser, ensuring your data remains private and secure. The tool shows match counts in real-time and processes replacements instantly as you type.
Common Uses for Find and Replace
Fixing Typos
Quickly correct misspelled words throughout your document. Replace all instances of a typo with the correct spelling in one operation.
Updating Terminology
Change product names, brand names, or technical terms throughout your content. The preserve case option keeps your capitalization consistent.
Data Transformation
Use regex patterns to transform data formats, clean up imports, or restructure content. Perfect for converting dates, phone numbers, or URLs.
Code Refactoring
Rename variables, functions, or classes across your codebase. Whole word matching ensures you only replace exact matches.
Frequently Asked Questions
What does case-sensitive search mean?
When case-sensitive is enabled, Hello and hello are treated as different text. The search will only match text with the exact same capitalization as your search term.
What does whole word matching do?
Whole word matching only finds complete words, not partial matches. For example, searching for "the" will not match "there" or "them". This prevents unintended replacements.
How do I use regular expressions?
Enable the "Use Regular Expression" option to use regex patterns. Common patterns include \d for digits, \w for word characters, and . for any character. Use $1, $2 in the replacement to reference captured groups.
What does preserve case do?
Preserve case maintains the capitalization pattern of the original text. If replacing "cat" with "dog", then "Cat" becomes "Dog", "CAT" becomes "DOG", and "cat" stays "dog".
Is my data secure?
Yes, all find and replace processing happens directly in your browser. Your text is never sent to any server or stored anywhere. This ensures complete privacy for sensitive documents or code.
