Find and Replace Text
The find-and-replace you wish every text box had. Swap words, fix typos across a whole document, or run regex patterns — right in your browser with no setup required.
How Find and Replace Works
This tool scans your text for matches and replaces them with your specified text. All processing happens in your browser — no data is sent to any server.
Enter the text you want to find and the replacement text. The tool shows how many matches exist before you replace. Options include case-sensitive matching, whole word matching, and regular expression support.
Regular expressions enable powerful pattern matching. Replace all email addresses, phone numbers, or specific text patterns with a single operation.
Common Use Cases
Fix typos across documents: Replace a misspelled word throughout an entire manuscript, report, or article in one click.
Update product names: When a product gets renamed, bulk replace all instances in documentation or marketing materials.
Code refactoring: Rename variables, functions, or classes across code files. Use regex for more complex patterns.
Format data: Add or remove formatting from lists, CSV files, or structured data.
Remove unwanted text: Strip out boilerplate text, watermarks, or repeated phrases from copied content.
Standardize terminology: Replace multiple variations of a term with a single consistent version.
Regular Expression Examples
Remove extra spaces: Find \s+ and replace with a single space to normalize whitespace.
Swap first and last names: Find (\w+)\s+(\w+) and replace with $2 $1 to reverse name order.
Add commas to numbers: Use regex to format large numbers with thousand separators.
Extract or replace emails: Find \b[\w.-]+@[\w.-]+\.\w+\b to match email addresses.
Replace dates: Convert date formats like MM/DD/YYYY to YYYY-MM-DD using capture groups.
What to Know Before Using This Tool
Review before replacing: Always check the match count before replacing. Unexpected matches can occur, especially with common substrings.
Regex requires escaping: Special characters like ., *, and ? have special meaning in regex. Escape them with \ to match literally.
Whole word prevents partial matches: Without whole word matching, replacing "he" would affect "the", "here", and "help".
Large texts work fine: The tool handles documents of any size, but very large replacements may take a moment.
