Online Text Replacement
About Online Text Replacement Tool
Tool Introduction
This is an efficient online batch text replacement tool. Simply enter the find and replace content at the top to complete text replacement in one click. The tool supports multiple matching modes and meets the needs of daily text processing, code refactoring, document editing, and more.
Matching Mode Description
The tool provides three matching modes: 1. Case sensitive—when enabled, "Apple" and "apple" are treated as different content; 2. Whole word matching—only replaces complete words, avoiding partial matches (for example, searching for "cat" will not replace "cat" in "category"); 3. Regular expression—supports advanced find and replace using regex syntax (such as \d+ to match all numbers).
Privacy and Security
This tool runs entirely locally in your browser. All find and replace logic is handled by front-end JavaScript, and none of your text content is uploaded to a server. You can safely process sensitive data, code files, or business documents.
Tips
Recommended workflow: 1. Paste the original text on the left; 2. Enter the find and replace content; 3. Adjust matching options and view the result on the right in real time; 4. If you want to keep the result, click "Overwrite original with result" to continue secondary processing, or click "Copy result" to export.
