About Regex Tester
A Regular Expression (Regex) is a sequence of characters that specifies a search pattern. This powerful tool allows you to test your regex patterns against any text, highlight matches, and perform complex search-and-replace operations. It's an indispensable resource for developers, data scientists, and anyone working with text manipulation.
Features:
- Real-time regex pattern validation
- Interactive testing of regex against sample text
- Support for various regex flags (Global, Case-Insensitive, Multiline, Dotall, Unicode, Sticky)
- Detailed display of all matches and capturing groups
- Perform find and replace operations with ease
- Clear and concise interface
How to use:
- Enter your regular expression in the "Regular Expression" field.
- Select any desired flags (e.g., 'g' for global match, 'i' for case-insensitive).
- Paste or type your test string into the "Test String" area.
- Click "Test Regex" to see all matches and their details in the "Matches Found" section.
- (Optional) Enter a "Replacement String" and click "Replace All" to see the modified text in the "Replaced Text" area.
- Use the "Copy" button to save the replaced text to your clipboard.
