Extract text from ERM files
To convert your ERM file to another format, you need Eclipse (ERMaster) or other Developer software.
To convert other file formats to the "Database Modeling" file type, you need software like Eclipse (ERMaster) or a similar tool.
The .ERM extension usually refers to an Entity-Relationship Diagram created by ERMaster, a popular plugin for the Eclipse IDE. These files rely on XML to store database schema structures, table relationships, and visual layout data. While excellent for developers actively designing databases within Eclipse, .ERM files are problematic for sharing with stakeholders or documenting systems outside the development environment. They require the specific IDE configuration to open, making them inaccessible to project managers or DBAs not using that specific toolchain.
Users frequently need to convert these files to bypass the "Eclipse lock-in." For documentation and presentations, converting .ERM to PDF, PNG, or JPEG is standard practice, allowing the diagram to be viewed without specialized software. For implementation, the primary goal is often generating standard SQL (DDL) scripts to build the database on platforms like MySQL or PostgreSQL.
Note: A distinct minority of .ERM files are Event Related Model scripts used in mods for Heroes of Might and Magic III (specifically the Wake of Gods expansion). These are plain text scripts and should be converted to TXT for easy editing in standard text editors like Notepad++. Rarely, an .ERM file may be a digital workspace archive from OpenText eRoom, which is essentially a renamed ZIP file.
Convert.Guru analyzes your ERM file, detects the exact format, and lets you read the text inside.
Users also converted XML, RBXM, E3D and DRN files.
If you want to convert ERM file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Eclipse (ERMaster) or similar software from the "Entity-Relationship Diagram" 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 ERM, try Eclipse (ERMaster) or another comparable tool in the "Entity-Relationship Diagram" category.
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 ERM converter.
