Convert XMI to another file type
To convert your XMI file to another format, you need StarUML or other Developer software.
Convert a file to XMI
To convert other file formats to the "Model Interchange Format" file type, you need software like StarUML or a similar tool.
About XMI files
The .xmi file extension primarily indicates a XML Metadata Interchange file, a standard defined by the Object Management Group for exchanging UML (Unified Modeling Language) diagrams between different software tools. While useful for developers, these files are raw XML code, meaning you cannot double-click them to see a visual diagram. A common source of frustration is that XMI files often contain only the abstract model structure (classes, attributes) but lack the "Diagram Interchange" data, meaning the visual boxes and lines are lost when moving between tools like Enterprise Architect and StarUML. To view the content as a diagram, you must import the file into a compatible modeling tool and then export it to PDF, PNG, or SVG.
Note: A small percentage of .xmi files are Extended MIDI audio files used by the Miles Sound System in older PC games, or IBM TSO/E TRANSMIT datasets used for mainframe file transfers. These require specialized players or unpackers and cannot be opened with text editors.
Convert.Guru analyzes your XMI file, detects the exact format, and lets you read the text inside.
If you want to convert XMI file to UML, XML, PLANTUML, JSON, PDF, MIDI, CSV, YAML, YML, TOML, INI or CFG, you can use StarUML or similar software from the "UML Model Interchange" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to XMI, try StarUML or another comparable tool in the "UML Model Interchange" category.
The XMI Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our XMI converter.
