Regex Tester & Validator

This regex pattern captures alphanumeric sequences or punctuation marks adjacent to text, useful for normalizing spacing in text. It can identify both sequences of letters, numbers, and spaces, as well as punctuation marks (like commas, periods, quotes, etc.) that are followed by alphanumeric characters or end of string. Common applications include text processing, cleaning up user-generated content, or ensuring consistent spacing between words and punctuation in natural language text.
