Convert a file to ARN
To convert other file formats to the "Diagnostic Report File" file type, you need software like Sysinternals Autoruns or a similar tool.
About ARN files
The .ARN file is a proprietary binary data file created by Microsoft Sysinternals Autoruns. Autoruns is a popular system diagnostic tool that identifies all programs configured to run automatically when a Windows system boots or a user logs in. When an IT administrator or security analyst saves the current system startup state, Autoruns exports the data into an .ARN file. This allows for offline analysis or future comparisons to detect newly added malware persistence mechanisms.
Despite its usefulness in system forensics, the .ARN format has significant disadvantages. It relies on the proprietary Microsoft Compound binary structure. You cannot open an .ARN file with standard text editors like Notepad or analyze it directly in Microsoft Excel. To read the file, you must have the Autoruns executable downloaded and running on a compatible Windows machine. This limitation frustrates security teams who want to parse logs on Linux or macOS workstations, or those who need to ingest the data into centralized logging platforms.
To bypass these restrictions, you must convert the file. For data analysis and spreadsheet viewing, convert .ARN to CSV. For quick text reviews, convert to TXT. If you are building automated log ingestion pipelines, convert to structured formats like JSON or XML. Just drag and drop your file here to analyze and convert it - free, online, and without installing software.
Use Convert.Guru to open and convert your ARN file.
If you want to convert ARN file to URL, JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO or RS, you can use Sysinternals Autoruns or similar software from the "Windows Startup Configuration Snapshot" 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 ARN, try Sysinternals Autoruns or another comparable tool in the "Windows Startup Configuration Snapshot" category.
The ARN 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 ARN converter.
