About this pattern
Number patterns appear constantly in form validation, log parsing, and data extraction. Regex is great for matching the shape but limited for semantic checks (range validation, mathematical constraints).
Quick usage in different languages
This exact pattern — with the correct escaping and idioms for each language:
- JavaScript:
/^€?\s?-?(\d{1,3}([.,]\d{3})+|\d+)([.,]\d{2})?\s?€?$/.test(value) - Python:
re.match(r"^€?\s?-?(\d{1,3}([.,]\d{3})+|\d+)([.,]\d{2})?\s?€?$", value) - Java:
Pattern.compile("^€?\\s?-?(\\d{1,3}([.,]\\d{3})+|\\d+)([.,]\\d{2})?\\s?€?$").matcher(value).matches() - C# / .NET:
Regex.IsMatch(value, @"^€?\s?-?(\d{1,3}([.,]\d{3})+|\d+)([.,]\d{2})?\s?€?$") - Go:
regexp.MustCompile(`^€?\s?-?(\d{1,3}([.,]\d{3})+|\d+)([.,]\d{2})?\s?€?$`).MatchString(value) - Ruby:
/^€?\s?-?(\d{1,3}([.,]\d{3})+|\d+)([.,]\d{2})?\s?€?$/.match?(value) - PHP:
preg_match('~^€?\s?-?(\d{1,3}([.,]\d{3})+|\d+)([.,]\d{2})?\s?€?$~', $value)
The explainer’s Code tab regenerates these for any pattern you paste, and the downloadable cheat sheet bundles the breakdown, all seven snippets, and the pitfalls below onto one printable page.
Common pitfalls
- Anchored to the whole string. This pattern uses ^ and $, so it requires the entire input to match. To find it inside a longer text, drop the anchors and use the global (g) flag.
- Escape it correctly per language. In Java and JavaScript strings each backslash must be doubled (\\d); in Python, Go, and C# use raw/verbatim strings so the backslashes survive.
- Validate beyond format. Matching the format doesn't guarantee the value is real. Confirm the euro amount against a source of truth (database, API, or checksum) where it matters.
Standards & sources
This pattern is based on the following authoritative specification(s) and issuing authorities. Formats can change — always confirm against the primary source.
