Convert EDMX to another file type
To convert your EDMX file to another format, you need Microsoft Visual Studio or other Developer software.
Convert a file to EDMX
To convert other file formats to the "Database Schema / ORM" file type, you need software like Microsoft Visual Studio or a similar tool.
About EDMX files
The .EDMX file acts as the "brain" for legacy .NET applications using Microsoft Entity Framework (specifically EF6 and older). It is a monolithic XML document that strictly defines three layers of an application's data architecture: the storage model (SSDL), the conceptual model (CSDL), and the mapping between them (MSL). While designed to be managed visually via the ADO.NET Entity Data Model Designer in Microsoft Visual Studio, these files often become a source of significant friction. Because they are auto-generated, they are notoriously difficult to merge in version control systems like Git, often leading to corruption if edited manually. Furthermore, modern .NET Core and EF Core have completely dropped support for .EDMX in favor of "Code First" workflows, rendering these files obsolete for new development but critical for maintaining legacy enterprise systems. Users typically need to convert them to SQL scripts to recreate the underlying database schema, PDF to document the complex entity diagrams for non-developers, or XSD to validate data structures during migration projects.
Convert.Guru analyzes your EDMX file, detects the exact format, and lets you read the text inside.
If you want to convert EDMX file to XSD, JSON, YAML, XML, WSDL, JS, TS, PY, JAVA, CPP, C or CS, you can use Microsoft Visual Studio or similar software from the "ORM Database Mapping" 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 EDMX, try Microsoft Visual Studio or another comparable tool in the "ORM Database Mapping" category.
The EDMX 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 EDMX converter.
