Convert DFD to another file type
To convert DFD diagrams to another format, you need Flowgorithm or other Developer software.
Convert a file to DFD
To convert other file formats to the "Flowchart Logic File" file type, you need software like Flowgorithm or a similar tool.
About DFD files
The .DFD file extension primarily acts as an Algorithm flowchart diagram file used by Flowgorithm. These files store the visual and logical steps of computer algorithms, allowing students and developers to simulate program execution. Secondary uses for the .DFD extension include statistical quality data formats for Hexagon Q-DAS software, duplicate file search projects in Duplicate File Detective (encoded in UTF-16 LE), and machine-to-machine UN/EDIFACT data interchange messages.
The main disadvantage of a .DFD file is its strict software lock-in. You cannot open a Flowgorithm diagram or a Q-DAS statistical report natively in a web browser, standard text editor, or mobile phone. Sharing these files means the recipient must download, install, and configure the exact same niche software - some of which require expensive enterprise licenses. EDIFACT .DFD files are exceptionally difficult to handle manually, as they contain raw, unformatted interchange strings that are virtually unreadable to humans without dedicated EDI parsers.
To share an algorithm flowchart with teachers, clients, or non-technical colleagues, convert the .DFD file to PDF for printing, or PNG and SVG for embedding into web pages and presentations. If you are dealing with statistical or EDI data, converting the file to CSV or XML is highly recommended for auditing and spreadsheet analysis. Drag and drop your file here to analyze and convert it - free, online, and without installing software.
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 storage" 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 storage" 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.
