Regex Editor & Tester

Parses itemized lines from a sales slip/receipt, likely Brazilian fiscal data (comma decimal separators, 'Desconto' discount lines, non-breaking space padding). Captures quantity, product code, description, unit code, price, a tax indicator in parentheses, and optionally a trailing discount amount shown as a negative value. Useful for extracting structured purchase line items from POS receipts or cupom fiscal documents.
