Regex Tester & Validator

This regex matches euro amounts with a comma as decimal separator, where the number has up to three digits before the comma and exactly two digits after, such as 123,45 or 42,00. It uses a lookahead to ensure the amount is immediately followed by <span>EUR</span>, making it ideal for extracting prices from HTML snippets or web pages. Common use cases include web scraping, parsing financial data, and identifying euro-denominated values in structured documents.
