Data Extraction tips

⛏️

Extract all email addresses, phone numbers, prices, or dates from a block of text by building a global-flag pattern and testing it here first.

💡

Capture groups let you extract specific parts of a match. ([\w.-]+)@([\w.-]+) captures username and domain separately in groups 1 and 2.

🔍

The match details panel shows every match with its position and captured groups — exactly what you'd get from JavaScript's match() or Python's findall().

🌟

Enable the "s" (dotall) flag to make . match newlines too — essential when extracting content that spans multiple lines.
