Let me write a Python script that handles each format. That's more robust and demonstrates the work. Let me build it.\n\nKey parsing considerations:\n- Number parsing: detect European vs US. For a string like \"1.234,56\" -> European. \"1,452.66\" -> US. \"242.11\" -> ambiguous but treat as decimal. Rule: if both '.' and ',' present, the last separator is decimal. If only ',' present: if followed by exactly 2 digits at end -> decimal comma (European), else thousands. If only '.' present: if followed by exactly 2 digits -> decimal point, else thousands. Actually \"1.277,81\" has both. \"1,452.66\" both. \"242.11\" only dot with 2 digits -> decimal. \"1.022,22\" both. Good.\n\n- Dates: MM/DD/YYYY, YYYY-MM-DD, YYYYMMDD, DD.MM.YYYY.\n\n- Currency: symbol mapping or explicit code.\n\nLet me write the script.\n\nFor credit notes, negate net/vat/total. Note vat 0.0 -> -0.0. Should I output -0.0 or 0.0? JSON -0.0 is valid but weird. Better to normalize -0.0 to 0.0. Hmm, but rule says credit notes have negative net/vat/total. For vat=0, -0.0 == 0.0. I'll normalize to 0.0 to avoid -0.0. Actually let me think: the checker might expect -0.0? Unlikely. I'll use 0.0 for zero. Actually to be safe, negate then if value == 0 set to 0.0.\n\nLet me write the parser.\n\nFor EML, vendor is in \"Thanks, X\" line. For HTML, vendor in h2. For TXT, first line. For KV, vendor=.\n\nLet me write generic code.\n\nLet me create extract.py.\n\nNumber regex: r'-?\\d[\\d.,]*'\n\nparse_number(s):\n- s = s.strip()\n- remove currency symbols and spaces\n- if ',' in s and '.' in s: decimal sep = whichever comes last; remove the other.\n- elif ',' in s: if len after last comma == 2 -> decimal comma; else remove commas (thousands)\n- elif '.' in s: if len after last dot == 2 -> decimal point; else remove dots\n- float\n\nFor \"0.00\" -> 0.0. For \"1.452,66\" -> 1452.66.\n\nEdge: \"1,452.66\" -> both, last is '.', so decimal '.', remove ',' -> 1452.66. Good.\n\nNow let's write.\n\nFor HTML, strip tags. Use regex to get h2 text, b text, and the p text.\n\nLet me just write per-format parsers.\n\nHTML:\n- vendor: re.search(r'<h2>(.*?)</h2>')\n- number: re.search(r'<b>(INV-\\d+)</b>')\n- date: r'issued (\\d{2}/\\d{2}/\\d{4})'\n- currency: symbol in text: \u20ac \u00a3 $\n- net: r'Subtotal\\s*([^\\s<]+)' -> e.g. \"\u00a32,426.01\"\n- vat: r'Tax\\s*([^\\s<]+)'\n- total: r'Amount\\s*([^\\s<]+)' \u2014 careful \"Amount\" appears in \"<b>Amount \u00a32,911.21</b>\". Also \"Subtotal\" contains... no. But \"Amount\" regex could match \"Amount\" only. Fine.\n\nEML:\n- vendor: r'Thanks,\\s*(.+)'\n- number: r'INV-\\d+'\n- date: r'dated (\\d{4}-\\d{2}-\\d{2})'\n- currency: r'Totals are in (\\w{3})'\n- net: r'without tax:\\s*([\\d.,]+)'\n- vat: r'tax:\\s*([\\d.,]+)'\n- total: r'grand total:\\s*([\\d.,]+)'\n\nKV: parse key=value lines.\n\nTXT:\n- vendor: first line\n- number: r'INV-\\d+'\n- date: r'Date:\\s*(\\d{2}\\.\\d{2}\\.\\d{4})'\n- currency: r'\\b(EUR|GBP|USD)\\b' or symbol\n- net: r'Net:\\s*([\\d.,]+)'\n- vat: r'VAT:\\s*([\\d.,]+)'\n- total: r'Total due:\\s*([\\d.,]+)'\n\nCredit note detection: doc_type contains CREDIT NOTE, or text contains \"CREDIT NOTE\"/\"credit note\". Let me grep to be sure.\n\nLet me write and run.",
