Extract text from DOSBox audio captures (DRO)
To convert DRO audio captures to another format, you need MeterView or other Data software.
To convert other file formats to the "Smart Meter Readout" file type, you need software like MeterView or a similar tool.
A .dro file is a proprietary Electricity Meter Data Readout generated by Iskraemeco smart energy meters. These files are created by specialized diagnostic software like MeterView to store raw electrical consumption data, load profiles, and billing registers extracted from residential or commercial meters. Alternatively, in the retro gaming community, a .dro file acts as a DOSBox Raw OPL audio file used to capture synthesizer music from MS-DOS emulators like DOSBox.
The primary disadvantage of the Iskraemeco .dro format is extreme vendor lock-in. It is a strictly closed, industrial data format containing raw hardware communication frames (often transmitted via the legacy IEC 62056-21 protocol). This makes the file exceptionally annoying to handle. You cannot open it natively in Microsoft Excel or standard text editors without encountering garbled text. Furthermore, the file is highly dependent on external "parameter schemes" to decipher the data; without the exact software configuration used during the initial readout, the numbers are meaningless.
To actually analyze your power consumption, you need to convert the .dro file to an accessible tabular format like CSV, TXT, or XLSX. Exporting to these formats makes the data compatible with modern analytics tools, though you will lose the original hardware frame control characters and raw diagnostic metadata in the process.
Because .dro is deeply proprietary and tied to specific physical hardware, standard online converters routinely fail to process it. Usually, only the original Iskraemeco software can properly read or export the structured tables. However, you can just drag and drop your file to identify the format, view it, and convert it when possible on convert.guru. Even if full conversion is blocked by proprietary encoding, our analyzer will inspect the binary contents and extract any readable plain-text strings or embedded data blocks, giving you a pragmatic way to salvage critical billing values without buying expensive enterprise software.
Convert.Guru analyzes your DRO file, detects the exact format, and lets you read the text inside.
Users also converted POF, VCAX and JBI files.
If you want to convert DRO file to , you can use MeterView or similar software from the "Electricity Meter Data Readout" category. In the File menu, look for Save As… or Export….
To convert files to DRO, try MeterView or another comparable tool in the "Electricity Meter Data Readout" 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 DRO converter.
