Convert XMI to another file type
To convert XMI metadata files to another format, you need StarUML or other Developer software.
Convert a file to XMI
To convert other file formats to the "Metadata Interchange Model" file type, you need software like StarUML or a similar tool.
About XMI files
An .xmi file primarily represents an XML Metadata Interchange document defined by the Object Management Group. It is an XML based format built to exchange Unified Modeling Language (UML) diagrams and system architectures between different software engineering tools. A secondary, completely unrelated use for .xmi is the Extended MIDI audio format developed for the Miles Sound System, heavily utilized for dynamic soundtracks in 1990s PC games. You will also occasionally encounter .xmi files on mainframes, where they act as IBM TSO/E TRANSMIT data transfer containers. Users frequently need to convert UML .xmi files because the format suffers from severe vendor lock-in. While the base model data transfers fine, visual diagram layouts and custom vendor extensions are frequently lost or corrupted when moving a file from StarUML to Eclipse Modeling Framework or Enterprise Architect. The format is heavily verbose and impractical for human reading without a dedicated parser. For audio .xmi files, modern operating systems natively reject them because they use proprietary chunk structures rather than the standard MID sequence. The best target formats for modeling .xmi files are standard XML for data parsing, or visual formats like PDF and PNG to preserve diagram layouts for non-technical stakeholders. Audio .xmi should be converted to MID or MP3 for modern playback. Standard online converters fail to process .xmi files because UML parsing requires complex, tool-specific engines, and Extended MIDI uses closed, legacy coding. Emphasize that often only the original software can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
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 "Model Data Exchange" 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 "Model Data Exchange" 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.
