About SDL files

The .SDL file extension most frequently represents a Salesforce Data Loader mapping file, a critical configuration component used to map columns from a CSV import file to specific fields within the Salesforce database. These files are essential for data migration but are often difficult to visualize outside the proprietary Java-based Data Loader tool. Because they rely on strict key=value syntax, a single formatting error can cause bulk import failures. Users also encounter .SDL files as SmartDraw symbol libraries or legacy Service Description Language files, both of which are incompatible with standard web browsers and office software. For Salesforce mappings, converting to TXT or XML facilitates easier auditing, version control, and debugging of complex field maps without opening the Data Loader. If you possess a SmartDraw library file, converting to PDF, PNG, or SVG ensures your diagrams and symbols are viewable by clients and colleagues who do not possess a paid license.

Convert.Guru analyzes your SDL file, detects the exact format, and lets you read the text inside.

Users also converted SDLPPX, SDLXLIFF, GRAPHQL, SDLPROJ, SDLTM, SDLRPX, SDLTB, GQL, STL, SLD, DOCX, PNG and PDF files.



The SDL 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 SDL converter.
