Convert RMK to another file type
To convert RMK OMR files to another format, you need Remark Office OMR or other Data software.
Convert a file to RMK
To convert other file formats to the "Optical Mark Recognition File" file type, you need software like Remark Office OMR or a similar tool.
About RMK files
The .RMK file format stores Optical Mark Recognition (OMR) test and survey data. It is primarily generated by Gravic Remark Office OMR, a widely used application for processing scanned forms, tests, and surveys using standard image scanners.
The main disadvantage of the .RMK format is severe vendor lock-in. It is a proprietary data container. Files cannot be opened natively by standard web browsers, nor can they be imported directly into common data analysis tools like Microsoft Excel or SPSS. Users without an active software license cannot view the grading data, making cross-team collaboration incredibly difficult.
To make the survey data actionable, you must convert the .RMK file to open formats like CSV, XLSX, or XML. Converting the file extracts the raw alphanumeric values (the captured bubbles and marks). However, be aware that the visual layout of the original scanned test form is lost, as .RMK only stores the extracted data points.
Because this is a closed, proprietary format, standard online converters usually fail to process it. Only the original software can reliably export the structured data. However, convert.guru provides a pragmatic workaround. Just drag and drop your file to identify the format, view its internal contents, and convert it when possible. If our analysis detects underlying plain text strings, viewing or partial conversion of the survey responses may still be possible.
Convert.Guru analyzes your RMK file, detects the exact format, and lets you read the text inside.

The RMK 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 RMK converter.
