Regex Generator

The Regex Generator is an interactive tool that helps you create regular expressions by analyzing your sample text. Instead of writing regex patterns from scratch, you paste an example of the text you want to match, and the tool identifies patterns such as IPs, Emails, URLs, dates, numbers, and words. Click the highlighted suggestions to select which parts to include in your regex, and the tool builds the pattern for you.

Whether you’re parsing log files, extracting data from strings, or validating input formats, this generator makes regex creation intuitive and visual. It runs entirely in your browser with no server round-trips.

Why Use This Regex Generator?

• Visual Pattern Selection: Click on detected patterns in your sample text instead of memorizing regex syntax. Complex structures like Emails, URLs, and IPs are highlighted for easy selection.
• Instant Feedback: See the generated regex update as you select or deselect patterns. Toggle options like “Generate Only Patterns” or “Match Whole Line” to refine the output.
• Shareable URLs: The tool supports URL parameters (sampleText and flags), so you can share your configuration with colleagues or bookmark common setups.
• TipTinker Aesthetic: A clean, high-contrast interface with yellow accents and bold typography makes pattern selection fast and enjoyable.
• No Backend Required: Everything runs client-side. Your sample text never leaves your device.

Key Features

• Smart Pattern Detection: Automatically identifies Email addresses, URLs, IP addresses, ISO 8601 dates, integers, floats, words, and whitespace in your sample text.
• Generate Only Patterns: Output only the selected pattern tokens, or include literal text between them for a full match.
• Match Whole Line: Wrap the generated regex with ^ and $ anchors for whole-line matching.
• Generate Lower Case: Use [a-z] instead of [A-Za-z] for case-sensitive, lowercase-only character classes.
• Regex Flags: Toggle Case Insensitive (i), Global (g), Multiline (m), and Dot All (s) flags.
• Copy to Clipboard: One-click copy of the generated regex for use in your code or tools.

How It Works

The tool tokenizes your sample text using a set of predefined pattern matchers. It tries to match, in order: URLs, Email Addresses, ISO Dates (e.g., 2020-03-12T13:34:56.123Z), IP Addresses (e.g., 192.168.1.1), floats, integers, words, and whitespace. Any character that doesn’t match these patterns is treated as a literal and safely escaped for regex. When you click a suggestion, that token’s pattern is added to or removed from the output.
