Extract text from DDL files
To convert your DDL file to another format, you need DLabel or other Database software.
To convert other file formats to the "Label Layout & SQL Script" file type, you need software like DLabel or a similar tool.
The .DDL extension represents a frequent file format collision between two distinct technical domains: label design and database management.
Most commonly, a .DDL file is an XML-based layout created by DLabel, a specialized software used for designing barcodes, shipping labels, and inventory tags. While these files are technically structured XML, they contain proprietary schema logic that renders them unreadable in standard text editors, appearing as a jumble of tags rather than a visual label. Users typically encounter friction when trying to share these designs with print shops or colleagues who do not have the DLabel suite installed, necessitating a conversion to PDF for proofing or PNG for digital previews.
Alternatively, in the developer ecosystem, .DDL stands for Data Definition Language. These are plain text scripts containing SQL commands (like CREATE, ALTER, or DROP) used to define database structures. Generated by systems like Oracle SQL Developer or PostgreSQL, these files are essential for archiving schema snapshots. However, they lack the visual formatting of a database diagram. Converting these scripts to PDF ensures a static, read-only copy for documentation, while converting to SQL or TXT ensures compatibility with universal code editors.
Convert.Guru analyzes your DDL file, detects the exact format, and lets you read the text inside.
Users also converted DLL, SQL, PNG, TXT, PDF, LABEL, DML, JPG, DDS, ZIP, MDB, EVTX and DOCX files.
If you want to convert DDL file to DBML, ERD, SQL, JSON, CSV, SDL, YAML, DB, SQLITE, SQLITE3, MDB or ACCDB, you can use DLabel or similar software from the "Label Design & Database Schema" 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 DDL, try DLabel or another comparable tool in the "Label Design & Database Schema" 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 DDL converter.
