What is Find Replace?
Find and Replace searches your text for specific words, phrases, or regex patterns and replaces them with new text. It supports case-sensitive and case-insensitive matching, whole-word matching, and full regular expression syntax for advanced replacements.
How to use Find Replace
- Paste your text into the input area.
- Enter the search term or regex pattern in the 'Find' field and the replacement text in the 'Replace' field.
- Toggle options like case sensitivity, whole-word match, or regex mode.
- Click 'Replace All' to apply changes and copy the updated text.
Why use this tool?
Batch-replacing text across a large document — like updating an old domain name, correcting a misspelled term, or reformatting dates with regex — is much faster with a dedicated find-and-replace tool than doing it line by line in a text editor.
FAQ
- Does it support regular expressions?
- Yes, you can enable regex mode to use full regular expression syntax including capture groups, lookaheads, and quantifiers.
- Can I use capture groups in the replacement string?
- Yes, when regex mode is enabled you can reference capture groups with $1, $2, etc. in the replacement field.
- What does 'whole word' matching do?
- It matches the search term only when it appears as a complete word, not as part of a larger word — for example, searching for 'cat' won't match 'category'.
- Is there a preview before replacing?
- Yes, matches are highlighted in the text before you apply replacements, so you can verify what will change.
- Is my text data kept private?
- Yes, all find-and-replace processing happens in your browser. No text is sent to any server.
Find Replace — In-Depth Guide
Find and replace is one of the most fundamental text editing operations, and this tool handles it without requiring a text editor or IDE. Paste your text, specify the search term and replacement, and process the entire document instantly. It is perfect for bulk text modifications, data cleanup, and standardizing terminology across large documents quickly.
Content managers use find and replace to update outdated terms, correct repeated spelling errors, or change product names across documentation. When a company rebrands or a product is renamed, this tool processes the change across large text blocks in seconds. It handles case-sensitive and case-insensitive matching to suit different replacement needs.
Developers use find and replace for refactoring tasks like renaming variables, updating API endpoints, or changing configuration values across multiple files. While IDEs offer built-in find and replace, this browser-based tool is useful for quick changes in text that is not in a project file, such as log outputs, database exports, or copied documentation.
Tip: always preview your replacements before applying them to catch unintended matches. The word address contains dress, so replacing dress with skirt would produce asskirt. Use whole-word matching when available to prevent partial word replacements. For complex pattern matching, use our Regex Tester tool which supports capturing groups and backreferences.
