{"success":true,"data":{"ext":"ods","name":"OpenDocumentSpreadsheet","description":"OpenDocument Spreadsheet (ODS) is an open spreadsheet file format defined by OASIS and standardized by ISO/IEC. It is used for worksheets, charts, formulas, and data analysis in office suites such as LibreOffice, Apache OpenOffice, and related applications. As a ZIP-based document container, it is generally safe, though spreadsheet files may contain macros or embedded content; older implementations may handle such features inconsistently.","mime":["application/vnd.oasis.opendocument.spreadsheet"],"risk_level":"Safe","signatures":[{"hex":"50 4B","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"}]},{"hex":"50 4B 03 04","offset":0,"sources":[{"name":"Wikipedia","url":"https://en.wikipedia.org/wiki/List_of_file_signatures"}]},{"hex":"50 4B 05 06","offset":0,"sources":[{"name":"Wikipedia","url":"https://en.wikipedia.org/wiki/List_of_file_signatures"}]},{"hex":"50 4B 07 08","offset":0,"sources":[{"name":"Wikipedia","url":"https://en.wikipedia.org/wiki/List_of_file_signatures"}]},{"hex":"6D 69 6D 65 74 79 70 65 61 70 70 6C 69 63 61 74 69 6F 6E 2F 76 6E 64 2E 6F 61 73 69 73 2E 6F 70 65 6E 64 6F 63 75 6D 65 6E 74 2E 73 70 72 65 61 64 73 68 65 65 74","offset":0,"sources":[{"name":"Neil Harvey FileSignatures","url":"https://raw.githubusercontent.com/neilharvey/FileSignatures/master/src/FileSignatures/Formats/OpenDocumentSpreadsheet.cs"}]}],"related":["ots","wks","xls","xlsx","xlt"],"usage":{"python":"def is_ods(file_path: str) -> bool:\n    \"\"\"Check if file is a valid ODS by magic bytes.\"\"\"\n    signature = bytes([0x50, 0x4B])\n    with open(file_path, \"rb\") as f:\n        return f.read(2) == signature","node":"function isODS(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x50, 0x4B]);\n  return buffer.subarray(0, 2).equals(signature);\n}","go":"func IsODS(data []byte) bool {\n    signature := []byte{0x50, 0x4B}\n    if len(data) < 2 {\n        return false\n    }\n    return bytes.Equal(data[:2], signature)\n}"},"category":"Office"}}
