What is a Find and Replace Tool?
A find and replace tool searches text for a string or pattern and substitutes it with new content. Plain-text mode matches exact characters (with optional case sensitivity), while regex mode uses patterns to target flexible structures such as dates, IDs, or repeated whitespace.
Our free online find and replace tool is built for writers, developers, and analysts who need quick bulk edits without opening a desktop editor or writing a one-off script. Paste your source text, set find and replace values, toggle options, and copy the updated result instantly.
Find & Replace Options
- Plain text mode:Match exact find strings with optional case-sensitive matching.
- Regex mode:Use JavaScript-style patterns for flexible search and capture-based replacements.
- Replace all:Update every match in one pass or limit changes to the first occurrence.
- Case sensitivity:Toggle whether uppercase and lowercase letters must match exactly.
- Replacement count:See how many substitutions were applied before you copy the output.
- Privacy:All processing happens in your browser — nothing is sent to a server.

No install, no account, and no wait for a server to process your text.
Find and Replace Tips
- •Test regex on a sample: Paste a small excerpt first to confirm your pattern matches only what you intend.
- •Escape special characters: In regex mode, dots, brackets, and backslashes often need escaping unless you mean them as operators.
- •Use replace-first for trials: Turn off replace-all to preview a single substitution before updating the entire document.
- •Watch case sensitivity: Product names and acronyms may need case-sensitive matching to avoid unintended swaps.
- •Count before you commit: Check the replacement count — zero matches or thousands both signal something to investigate.
- •Keep an original copy: Save the before text so you can re-run edits or diff against the source if needed.

Frequently Asked Questions
Does this tool support regular expressions?
Yes. Enable the regex toggle to use JavaScript-style patterns such as \d+ for digits or \s+ for whitespace. Invalid patterns are handled safely in your browser.
Can I replace only the first match?
Yes. Turn off the Replace all toggle to change only the first occurrence. When enabled, every match in your text is updated.
Does the tool show how many replacements were made?
Yes. A live replacement count tells you how many substitutions were applied so you can verify bulk edits before copying the output.
Is my text uploaded to a server?
No. All find-and-replace processing happens locally in your browser. Your text never leaves your device.
What is the difference between case-sensitive and case-insensitive search?
Case-sensitive matching requires exact letter casing ("API" won't match "api"). Case-insensitive mode treats uppercase and lowercase as equivalent.
Can I use capture groups in regex replacements?
Yes. JavaScript replacement syntax supports $1, $2, and similar references when regex mode is enabled and your pattern includes capturing groups.
What happens if my regex pattern is invalid?
Invalid patterns are caught in the browser. The tool avoids crashing and lets you fix the pattern before applying replacements.
Is the find and replace tool free?
Yes. Free unlimited use with no registration or downloads required.
