Pre-Built Regex Patterns for Developers

Writing regular expressions from scratch is error-prone and time-consuming. Our Regex Generator provides patterns for the most common validation scenarios, complete with code snippets for JavaScript and Python.

How to use Regex Pattern Generator

  1. Paste or type your input into the editor on the left.
  2. Leave the defaults, or tweak them if the tool exposes options.
  3. The result appears on the right as you type.
  4. Copy the output or download it.

This tool runs in your browser. Your input is not uploaded or stored.

Use it from the API

Everything this page does is also available as a REST endpoint, so you can call Regex Pattern Generator from your own code, a script or a CI pipeline.

Bash
curl "https://api.toolsxpo.com/v1/regex-generator" \
  -H "Authorization: Bearer txp_live_YOUR_KEY"

The endpoint returns a JSON envelope ({ ok, data, meta }) and costs 1 credit per successful call. Try it in the playground or browse the full API reference.
