About ATD files
The .ATD file format is a highly fragmented extension used across several unrelated proprietary software systems. Its most common use cases are as an Ancestris family tree file relying on the ComponentAce Absolute Database engine, or as an XML-based fiber optic test report generated by Anritsu OTDR test equipment. Other variations include automated test data for Takaya flying probe testers, 3D model data for Afanche3D, and CAM data for Alma Actcut. This extreme fragmentation means an .ATD file is entirely useless until you identify its specific source. The disadvantages of the .ATD format are severe. It is deeply proprietary, lacks native support in mainstream operating systems or web browsers, and strictly enforces vendor lock-in. If you receive an .ATD file from a telecom contractor or a family historian, you cannot simply double-click to view it without purchasing or installing highly specialized, often expensive software. Furthermore, .ATD files generated as databases are prone to permanent data loss if the proprietary database engine corrupts the file. To make .ATD files accessible, you must convert them into standardized, universal formats. For web use and data parsing, converting XML-based .ATD test reports to XML or JSON is highly recommended to preserve the structured hierarchy. For archiving fiber optic test results or CAM schematics, convert the file to a static PDF/A document to ensure long-term readability. If the file contains tabular test data, extracting it to CSV ensures complete compatibility with Microsoft Excel and other spreadsheet software. Our platform immediately identifies the underlying .ATD variant and extracts the usable data for you.
Convert.Guru analyzes your ATD file, detects the exact format, and lets you read the text inside.

The ATD 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 ATD converter.
