Extract text from Data models (DM1)
To convert DM1 models to another format, you need erwin Data Modeler or other Database software.
To convert other file formats to the "Data Model Diagram" file type, you need software like erwin Data Modeler or a similar tool.
The .dm1 file extension is used for Data Model Diagram files. These files store complex database schemas, including logical and physical data models, entity-relationship (ER) diagrams, table structures, and indexing constraints. They are predominantly created by two major enterprise data architecture tools: erwin Data Modeler (historically owned by CA Technologies and Quest) and IDERA ER/Studio (formerly Embarcadero). Both enterprise tools use the .dm1 extension, though their internal file structures are entirely different and completely incompatible with each other.
The main disadvantage of a .dm1 file is its extreme vendor lock-in. These are highly proprietary, closed-source formats designed for expensive enterprise software. Without an active, costly subscription to erwin or ER/Studio, it is practically impossible to view the database schemas. They are not supported by standard document viewers or web browsers, making sharing technical diagrams with developers or stakeholders extremely difficult. Standard online converters completely fail to process them because the logical architecture inside cannot simply be mapped to a standard image or document without the original software's proprietary rendering engine.
To effectively share a .dm1 file, the best approach is to open it in its native software and export the visual diagrams to standard target formats like PDF, PNG, or SVG. For deploying the actual database structure, exporting to a SQL Data Definition Language (DDL) script is required.
Because .dm1 is a closed, enterprise-grade format, third-party conversion is inherently limited. However, you can drag and drop your file into convert.guru to see what it is and convert it if supported. Our analyzer can inspect the file signature to determine whether it originated from erwin or ER/Studio and extract readable text strings, such as table and column names. If our analysis detects a supported embedded format or readable metadata, partial viewing or conversion may still be possible.
Convert.Guru analyzes your DM1 file, detects the exact format, and lets you read the text inside.
Users also converted DM, ZIP, ERWIN, CDM and ER1 files.
If you want to convert DM1 file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use erwin Data Modeler or similar software from the "Database Entity-Relationship Modeling" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to DM1, try erwin Data Modeler or another comparable tool in the "Database Entity-Relationship Modeling" 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 DM1 converter.
