Convert ACU to another file type
To convert ACU files to another format, you need ACUCOBOL-GT or other Developer software.
Convert a file to ACU
To convert other file formats to the "Compiled COBOL Object File" file type, you need software like ACUCOBOL-GT or a similar tool.
About ACU files
A .acu file primarily functions as a compiled object file generated by the ACUCOBOL-GT compiler, a legacy COBOL development environment originally created by Acucorp. Less commonly, it serves as an AutoChart sonar log file created by Humminbird marine electronics, or a specialized financial data submission file used by the Ecuadorian Companies Superintendency.
These formats are strictly proprietary and highly specialized. The ACUCOBOL variant contains machine-readable compiled code, not human-readable text. It requires a specific runtime environment to execute and cannot be directly edited in a standard text editor. The Humminbird AutoChart log and financial submission formats are equally closed, locking data into specialized viewing software like AutoChart PC or ACU Report Viewer. Users face extreme difficulty trying to extract data from these files without expensive, specialized, or obsolete original software.
Standard online converters fail to process .acu files because they lack documented, open specifications. Converting a compiled COBOL object back to source code (CBL) requires specialized decompilation tools, which are rarely accurate. For sonar data, users typically want to export to CSV or GPX, while financial reports are best exported to PDF.
This file format is exceptionally difficult to open or convert because often only the original software can properly read or export the data. Standard tools simply cannot parse the proprietary binary structures. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your ACU file, detects the exact format, and lets you read the text inside.
If you want to convert ACU file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use ACUCOBOL-GT or similar software from the "Compiled COBOL Object Code" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to ACU, try ACUCOBOL-GT or another comparable tool in the "Compiled COBOL Object Code" category.
The ACU 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 ACU converter.
