Regex to String Generator
Generate random strings that match a given regular expression pattern
## Regex to String Generator
Generate random test strings that match a given regular expression pattern. Useful for generating test data, validating regex patterns, and creating sample data that matches specific patterns.
**Instructions:**
1. Enter a regular expression pattern (without including slashes)
2. Optional: Add flags (such as g, i, m, s, u, y)
3. Set the number of strings to generate (1-50)
4. Set the maximum length for each string (1-100)
5. Click generate to view the matching strings
**Supported Regex Features:**
- Character classes: `[a-z]`, `[0-9]`, `[abc]`
- Quantifiers: `*`, `+`, `?`, `{n}`, `{n,m}`
- Groups: `(...)`
- OR operator: `|`
- Escape characters: `\d`, `\w`, `\s`, etc.
- Predefined character sets: `.` (any character except newline)
**Notes:**
- Anchors `^` and `$` are ignored
- Some complex regex patterns may not generate valid strings
- Generated strings are validated to ensure they match the pattern
