Convert ArchiCAD and AspenTech files (APX) online for free
The converter easily converts your APX files to various formats - free and online. No ArchiCAD or or other Plugin software needed.
To convert other file formats to the "Software Extension" file type, you need software like ArchiCAD or a similar tool.
The .APX file extension is heavily fragmented and used across multiple niche, proprietary systems. Its most common uses include ArchiCAD Add-on files developed by Graphisoft, which add specific functions to the architectural CAD software (these are essentially compiled Windows executables), and AspenTech Process Explorer trend plot files, which store process data graphs (built on the Microsoft Compound Document format). Other variations include AmiBroker financial project files (XML-based), Agilent Seahorse XF assay data (ZIP-based), and rare bitmap images from legacy software like MXPaint or Leica microscopes.
Because .APX serves so many different roles, dealing with it is notoriously frustrating. If you do not have the exact software - like a pricey AspenTech subscription or an active ArchiCAD license - these files are essentially locked digital boxes. Add-on variants are executable extensions that cannot be natively viewed or edited, posing a strict platform lock-in. Trend plot or financial variants store valuable data but lock it away from standard reporting tools. The files cannot be natively opened by web browsers or mobile devices.
To unlock your data, conversion is highly recommended based on your file's underlying type. For AspenTech plots or AmiBroker projects, convert to CSV or XLSX for spreadsheet analysis, or to PDF for archiving and sharing reports. If it is an .APX image file (Leica or MXPaint), convert it to PNG or JPG for broad web and viewer compatibility. Just drag and drop your file here to analyze and convert it - free, online, and without installing software on convert.guru.

To convert RAW, PNG, AI, NEF, PSB, DNG, SVG, GIF, EPS, JPG, ARW or PDF files to APX, try ArchiCAD or another comparable tool in the "Software Extensions and Plot Data" category.
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 APX converter.
