{"success":true,"data":{"ext":"wb3","name":"Quatro Pro for Windows 7","description":"Quattro Pro for Windows 7 Notebook (WB3) is a spreadsheet file format developed by Borland and later maintained by Corel for the Quattro Pro application. It was used to store worksheets, formulas, charts, and related spreadsheet data in Quattro Pro for Windows 7 and compatible later versions. The format is now largely legacy and may require compatibility software to open, but it is generally considered safe when handled with standard office-document precautions.","mime":["application/x-quattro-pro"],"risk_level":"Safe","signatures":[{"hex":"3E 00 03 00 FE FF 09 00 06","offset":24,"sources":[{"name":"Gary Kessler","url":"https://www.garykessler.net/library/file_sigs_GCK_latest.html"}]}],"related":[],"usage":{"python":"def is_wb3(file_path: str) -> bool:\n    \"\"\"Check if file is a valid WB3 by magic bytes at offset 24.\"\"\"\n    signature = bytes([0x3E, 0x00, 0x03, 0x00, 0xFE, 0xFF, 0x09, 0x00, 0x06])\n    with open(file_path, \"rb\") as f:\n        f.seek(24)\n        return f.read(9) == signature","node":"function isWB3(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x3E, 0x00, 0x03, 0x00, 0xFE, 0xFF, 0x09, 0x00, 0x06]);\n  if (buffer.length < 33) return false;\n  return buffer.subarray(24, 33).equals(signature);\n}","go":"func IsWB3(data []byte) bool {\n    signature := []byte{0x3E, 0x00, 0x03, 0x00, 0xFE, 0xFF, 0x09, 0x00, 0x06}\n    if len(data) < 33 {\n        return false\n    }\n    return bytes.Equal(data[24:33], signature)\n}"}}}
