Convert DFD to another file type
To convert your DFD file to another format, you need Flowgorithm or other Developer software.
Convert a file to DFD
To convert other file formats to the "Flowchart Diagram" file type, you need software like Flowgorithm or a similar tool.
About DFD files
The .dfd file extension typically represents a Data Flow Diagram created by Flowgorithm, a popular educational tool used to visualize algorithms and programming logic. These files store flowchart structures in an XML-based format, allowing students and developers to execute logic without writing complex syntax. However, because .dfd files are proprietary to Flowgorithm, they cannot be opened in standard image viewers like Microsoft Paint or web browsers. To share your logic with non-users, you must convert the diagram to PDF for documentation, PNG for web embedding, or export the logic directly to source code languages like Java, C++, or Python.
In industrial settings, a .dfd file may alternatively be a Q-DAS Quality Data file used by Hexagon Q-DAS software. In this context, the file serves as a definition or catalog file (often paired with DFX data files) containing ASCII statistical quality control data. Engineers frequently need to convert these legacy text-based definitions into CSV or XLSX formats to analyze the data in Microsoft Excel or modern BI tools.
Convert.Guru analyzes your DFD file, detects the exact format, and lets you read the text inside.
If you want to convert DFD file to ERD, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT or DB, you can use Flowgorithm or similar software from the "Algorithm Flowchart Diagram" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to DFD, try Flowgorithm or another comparable tool in the "Algorithm Flowchart Diagram" category.
The DFD 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 DFD converter.
