Common Patterns

How to Use This Tool

Enter Your Pattern

Type your regular expression pattern in the pattern field. Add flags like g (global) or i (case-insensitive) as needed.

Add Test Text

Paste or type the text you want to test against your regex pattern in the test string area.

View Matches

Matches are highlighted in real-time. Capture groups and match details are displayed below the test area.

Input

Pattern: \d+ | Test: "abc 123 def 456"

Output

Match 1: "123" | Match 2: "456"

Use the global flag (g) to find all matches, not just the first one.
Capture groups are shown separately so you can verify your pattern extracts the right data.
Common patterns: \d+ for numbers, \w+ for words, .+? for non-greedy match.
