Extract text from ATO files
To convert your ATO file to another format, you need Across the Obelisk or other Game software.
To convert other file formats to the "RPG Save File" file type, you need software like Across the Obelisk or a similar tool.
The .ATO file extension presents a classic filename collision between the gaming world and high-end civil engineering. The most common iteration (approx. 70%) serves as the primary game save data for Across the Obelisk, a popular deck-building RPG. These files store critical campaign progress, deck states, and unlockables. The main source of friction here is their proprietary formatting; while users often wish to edit these files to modify difficulty or retrieve lost runs, the data is typically serialized or encoded, making it unreadable in standard text editors without first converting it to a structured format like JSON or XML.
Conversely, in the engineering sector, .ATO files function as Model Archives or Tool Option files for Autodesk Infraworks and related AutoCAD verticals. These are heavy, complex datasets containing infrastructure models, terrain data, or assembly configurations. The challenge for professionals is the extreme software dependency - you cannot view an .ATO file without a specific, often expensive, Autodesk subscription. Sharing these files with clients or stakeholders who lack the software is impossible without conversion. For visualization and collaboration, these should ideally be converted to more accessible 3D formats like FBX, OBJ, or even 3D PDF for archival purposes.

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 ATO converter.
