Accelerate your workflow and increase the consistency of your texts with precise, bulk edits. Our Find and Replace tool is the definitive solution for editors, programmers, data analysts, and any professional who needs speed and reliability when working with large volumes of text. With advanced options like case-sensitivity, whole word matching, and the power of Regular Expressions (RegEx), you can perform everything from simple corrections to the most complex code refactoring in seconds.
Ensure consistency and correct errors in manuscripts, articles, and documents with maximum efficiency.
Refactor code, update dependencies, and keep your codebase clean and functional.
Clean, standardize, and optimize data and web content for maximum performance.
This is your primary defense against errors. Enabling "Whole Words" ensures that when searching for "art", you don't accidentally change "party" or "start". For professional edits, this option should almost always be active.
When capitalization matters (proper nouns, acronyms like "CEO," or variables in code), enable this option. When you want to normalize a term (ensure "brand," "Brand," and "BRAND" all become "Brand Name"), disable it.
RegEx is your superpower. Use `\s+` to find multiple spaces and replace them with a single one. Use `^` to find the start of a line or `$` for the end. It's the most powerful tool for complex data cleaning and code refactoring.
Made a mistake? No panic. The "Undo" button reverts the last replacement operation. Use "Replace" a few times to test the result before clicking "Replace All". This two-step approach offers speed with safety.
For critical documents or entire codebases, the golden rule is: copy the original text to a safe place before making bulk replacements. Our tool is precise, but a backup provides total peace of mind and allows for an easy before/after comparison.
The occurrence counter is your guide. Before replacing, see how many times the term appears. If the number is much higher than expected, it might be a sign that your search is too broad. Refine your search before acting to avoid unwanted results.

Replace: Changes only the next found occurrence (or the selected one), giving you full, step-by-step control. Ideal for careful reviews.
Replace All: Changes all occurrences at once. It's the option for maximum efficiency when you are confident in your search.
RegEx is a "language" for finding patterns in text. Instead of searching for fixed text, you search for "rules." Use it for advanced tasks like finding all email addresses, removing all HTML tags from a text, or finding lines that start with a number. It's a tool for advanced users.
You can use "capture groups." Wrap part of your RegEx in parentheses `()`. Then, in the replacement field, you can refer to that group with `$1` (for the first group), `$2` (for the second), and so on. For example, to swap "Smith, John", find `(\w+), (\w+)` and replace with `$2 $1` to get "John Smith".
Not directly. The "Whole Words" option is a shortcut for non-RegEx users. If you need this functionality with RegEx, you must add it manually to your pattern using `\b` (word boundary). Example: `\bword\b`.
Our tool is optimized to handle very large texts. However, performance may vary depending on your browser and the complexity of your search. For files of several hundred megabytes, it might be faster to process in chunks, which also gives you more control.
When checked, the search is case-sensitive, meaning "House" is different from "house." When unchecked, the search ignores case, and searching for "house" will find "house," "House," "HOUSE," etc.
Yes! This is one of our most important features. If you use "Replace All" and the result isn't what you expected, a single click on "Undo" reverts the entire operation, restoring your original text. This gives you the confidence to work quickly.
Once the page is loaded, the tool works entirely in your browser without needing an internet connection. All computation is done locally on your device.
Your data is 100% secure. Like all our tools, this one operates exclusively in your browser. No text you paste or type is ever sent to our servers. Your privacy and the confidentiality of your work are total.
Use Regular Expressions. To find line breaks (from either Windows or Unix), the safest pattern is `\r?\n`. You could, for example, find all double line breaks `(\r?\n){2,}` and replace them with a single line break `\n` to clean up a document's spacing.
Goal: Correct "teh" to "the" throughout a document.
Find: `teh`
Replace with: `the`
Options: Check "Whole Words".
Strategy Applied: Using "Whole Words" is crucial here to avoid accidentally changing words that contain "teh", like "whatever". The bulk replacement fixes a common error quickly and accurately.
Goal: Rename the variable `temp` to `temporaryData` in a script.
Find: `temp`
Replace with: `temporaryData`
Options: Check "Whole Words" and "Case-Sensitive".
Strategy Applied: In code, precision is everything. "Whole Words" avoids changing `template` or `attempt`. "Case-Sensitive" ensures only the exact variable is changed in case-sensitive languages like JavaScript.
Goal: Change all links from `http://` to `https://`.
Find: `http://`
Replace with: `https://`
Options: None extra needed.
Strategy Applied: A fundamental SEO and security task. Bulk replacement is the only feasible way to do this on a site with hundreds of pages, ensuring all links are secure with a single click.
Goal: Remove all quotation marks from a CSV file.
Find: `"`
Replace with: (leave blank)
Options: None.
Strategy Applied: A very common data cleaning task. Leaving the replacement field empty effectively deletes the found term. This prepares the data to be imported correctly by another system.
Goal: Change "Lastname, Firstname" to "Firstname Lastname".
Find: `(\w+), (\w+)`
Replace with: `$2 $1`
Options: Check "Use Regular Expressions".
Strategy Applied: This is a prime example of the power of RegEx capture groups. `(\w+)` captures a word. `$2 $1` reverses the order of the captured words. This automates a complex formatting task that would be impossible with a normal search.
Goal: Remove all excess spacing between paragraphs.
Find: `(\r?\n){2,}`
Replace with: `\n`
Options: Check "Use Regular Expressions".
Strategy Applied: The RegEx pattern finds two or more consecutive line breaks and replaces them with a single one. This instantly cleans up and standardizes the formatting of an entire document, a task that would be extremely tedious manually.
