โ“ FAQ

How does text to regex work?

The tool analyzes pattern features in input text (digits, letters, special characters, length, delimiters), auto-detects common formats (email, phone, date, URL), and generates corresponding regex expressions.

What common formats are supported?

Supports auto-detection of email, phone number, date, URL, IP address, zip code, hex color, file path and other common formats, plus custom pattern analysis.

Is the generated regex accurate?

The generated regex is based on pattern analysis and provides approximate matching. For complex scenarios, manual adjustment and testing are recommended.

Can I input multiple lines?

Yes. When multiple lines are input, the tool analyzes common patterns across all lines and generates a universal regex that matches all of them.

How to test the generated regex?

The tool has built-in live testing. Enter test text to see match results and highlighting. Supports global match, case-insensitive, and multiline mode flags.

Can I export the generated regex?

Yes. Copy regex to clipboard with one click, or download as a text file. Also supports exporting as code snippets in multiple programming languages.
