Extract text from appraisal files (APO)
To convert APO appraisals to another format, you need ActivePresenter or other Developer software.
To convert other file formats to the "Compiled Object / XML Data" file type, you need software like ActivePresenter or a similar tool.
The .APO file extension is heavily fragmented and serves entirely different purposes depending on the authoring software. It primarily functions as a compiled application object file in the 4D development environment, an ActiveX control within ActivePresenter, or an Appraisal order XML file generated by the ETRAC appraisal management platform.
Because multiple unrelated programs share this exact extension, dealing with .APO files is incredibly frustrating. The ETRAC variant is simply structured text, but the compiled objects (4D and ActivePresenter) are closed, proprietary binary formats. These executable variants are useless without purchasing or subscribing to the specific runtime environment that created them. They are not supported by web browsers, exceed standard attachment limits if bundled with heavy assets, and pose a severe security risk if executed blindly on your operating system.
If you have the ETRAC appraisal variant, converting to XML, CSV, or standard TXT is highly recommended for cross-platform compatibility. For the binary object variants, direct conversion is extremely rare; you must use the original authoring software to extract or recompile the data into a usable standalone format.
Because this file format is difficult to open or convert, standard online converters often fail to process it. Usually, only the original software can properly read or export the data. However, just drag and drop your file to convert.guru to identify the format, inspect the file, and show text or internal content. If our analysis detects a supported underlying XML or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your APO file, detects the exact format, and lets you read the text inside.

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 APO converter.
