Regex Tester & Validator

This regex matches lines starting with 'WS' followed by whitespace, then captures four groups: two arbitrary text fields separated by whitespace, a date in YYYY-MM format, and a trailing text field. It is useful for parsing structured log entries or tabular data where each record begins with 'WS' and includes a month-year date. Common use cases include extracting account details, transaction records, or system activity logs with a consistent delimiter.
