It was used to store worksheets, formulas, and related spreadsheet data in business and personal computing environments. The format is legacy and largely obsolete, but older files may still be opened by modern office suites; as with other documents, untrusted files should be handled carefully.","mime":["application/x-quattro-pro;version=1+5"],"risk_level":"Safe","signatures":[{"hex":"00 00 02 00 01 10","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]}],"related":["wb2","wk1","wk2","wkq","wq1","wq2"],"usage":{"python":"def is_wb1(file_path: str) -> bool:\n    \"\"\"Check if file is a valid WB1 by magic bytes.\"\"\"\n    signature = bytes([0x00, 0x00, 0x02, 0x00, 0x01, 0x10])\n    with open(file_path, \"rb\") as f:\n        return f.read(6) == signature","node":"function isWB1(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x00, 0x00, 0x02, 0x00, 0x01, 0x10]);\n  return buffer.subarray(0, 6).equals(signature);\n}","go":"func IsWB1(data []byte) bool {\n    signature := []byte{0x00, 0x00, 0x02, 0x00, 0x01, 0x10}\n    if len(data) < 6 {\n        return false\n    }\n    return bytes.Equal(data[:6], signature)\n}"}}}
