### 方法
|方法|描述|
| :- | :- |
| [`detect_file_format(, stream)`](/cells/python-net/zh/aspose.cells/fileformatutil/detect_file_format/#io.rawiobase) |检测并返回有关流中存储的 Excel 格式的信息。|
| [`detect_file_format(, stream, password)`](/cells/python-net/zh/aspose.cells/fileformatutil/detect_file_format/#io.rawiobase-str) |检测并返回有关流中存储的 Excel 格式的信息。|
| [`detect_file_format(, file_path)`](/cells/python-net/zh/aspose.cells/fileformatutil/detect_file_format/#str) |检测并返回有关文件中存储的 Excel 格式的信息。|
| [`detect_file_format(, file_path, password)`](/cells/python-net/zh/aspose.cells/fileformatutil/detect_file_format/#str-str) |检测并返回有关文件中存储的 Excel 格式的信息。|
| [`verify_password(, stream, password)`](/cells/python-net/zh/aspose.cells/fileformatutil/verify_password/#io.rawiobase-str) |检测并返回有关流中存储的 Excel 格式的信息。|
| [`file_format_to_save_format(, format)`](/cells/python-net/zh/aspose.cells/fileformatutil/file_format_to_save_format/#aspose.cells.fileformattype) |将文件格式转换为保存格式。|
| [`extension_to_save_format(, extension)`](/cells/python-net/zh/aspose.cells/fileformatutil/extension_to_save_format/#str) |将文件扩展名转换为 SaveFormat 值。|
| [`is_template_format(, extension)`](/cells/python-net/zh/aspose.cells/fileformatutil/is_template_format/#str) |如果扩展名是 .xlt、.xltX、.xltm、.ots，则返回 true。|
| [`load_format_to_extension(, load_format)`](/cells/python-net/zh/aspose.cells/fileformatutil/load_format_to_extension/#aspose.cells.loadformat) |将加载格式枚举值转换为文件扩展名。|
| [`load_format_to_save_format(, load_format)`](/cells/python-net/zh/aspose.cells/fileformatutil/load_format_to_save_format/#aspose.cells.loadformat) |如果可能，将 LoadFormat 值转换为 SaveFormat 值。|
| [`save_format_to_extension(, format)`](/cells/python-net/zh/aspose.cells/fileformatutil/save_format_to_extension/#aspose.cells.saveformat) |将保存格式枚举值转换为文件扩展名。|
| [`save_format_to_load_format(, save_format)`](/cells/python-net/zh/aspose.cells/fileformatutil/save_format_to_load_format/#aspose.cells.saveformat) |如果可能，将 SaveFormat 值转换为 LoadFormat 值。|
