Test, validate and match regular expressions
This regex matches arrays containing exactly three VK identifiers formatted as strings within single quotes, like ['VK-123', 'VK-456', 'VK-789']. It captures each VK-XXXX pattern separately, making it useful for extracting specific VK identifiers from CSV data or converting array-like string representations into structured data. The pattern specifically expects the VK prefix followed by a hyphen and one or more digits.
