Convert ERX to another file type
To convert ERX Models to another format, you need ER/Studio or other Database software.
Convert a file to ERX
To convert other file formats to the "Entity-Relationship Data Model" file type, you need software like ER/Studio or a similar tool.
About ERX files
.ERX files are primarily Entity-Relationship diagrams used to map complex database architectures. Approximately 68% of these files are generated by IDERA ER/Studio Data Architect, storing structural data in an XML format. Another 13% belong to erwin Data Modeler. Users rely on these files to visualize database tables, keys, and relationships. The main disadvantage of the .ERX format is its strict vendor lock-in. Opening or editing these files typically requires an expensive, enterprise-level software subscription. If you send an .ERX file to a stakeholder who does not have this specific software, they cannot view the database diagram. Because of this, users frequently need to convert .ERX files to standard visual formats like PDF, PNG, or SVG for sharing, or to SQL to deploy actual database schemas. Converting these files is notoriously difficult. Standard online converters fail because the internal structure contains proprietary spatial coordinates and vendor-specific data types that only the original application understands. However, because the majority of .ERX files are built on an underlying XML structure, you are not completely locked out. We can analyze the file to determine if it is an ER diagram, a compressed ZIP Eagle PACE report, or even a rare Nemetschek Allplan CAD executable.
Convert.Guru analyzes your ERX file, detects the exact format, and lets you read the text inside.
If you want to convert ERX file to DB, SQLITE, SQLITE3, MDB, ACCDB, DBF, ODB, FDB, GDB, MYD, FRM or SQL, you can use ER/Studio or similar software from the "Database Entity-Relationship Modeling" category. In the File menu, look for Save As… or Export….
To convert NDF, SQLITE3, BAK, RDB, SQL, DB4, MDF, MDB, LDF, DB, DB3 or SQLITE files to ERX, try ER/Studio or another comparable tool in the "Database Entity-Relationship Modeling" category.
The ERX 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 ERX converter.
