About MDM files
The .MDM file extension is a chameleon in the digital world, most frequently appearing as either a legacy Microsoft Jet Database file or a custom chart package for the rhythm game Muse Dash.
If you are dealing with the database variant, you are likely encountering a relic from older versions of Microsoft Access. These files often serve as Workgroup Information Files or specialized data containers that modern database software struggles to interpret natively. The proprietary nature of the Jet engine means your data - whether it is marketing figures or inventory lists - is effectively locked inside a "black box" unless you have the specific legacy drivers installed. For data preservation and accessibility, the best workflow is converting these tables into standard CSV, XLSX, or SQL formats, allowing you to migrate the information into modern systems like MySQL or Microsoft Excel without relying on obsolete software.
On the other hand, if you are a gamer, the .MDM file is likely a disguised ZIP archive containing level data, music, and charts for Muse Dash. The frustration here is simple: your operating system does not treat it as a folder. To access the JSON or BMS files inside, you often need to manually rename the extension or use an extractor. For engineers using Keysight IC-CAP, the file represents measurement data that is difficult to visualize outside the proprietary environment; converting to CSV or PDF reports is essential for sharing results with colleagues who do not possess the expensive licensing required to open the raw file.
Convert.Guru analyzes your MDM file, detects the exact format, and lets you read the text inside.
If you want to convert MDM file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Microsoft Access or similar software from the "Jet Database / Game Chart" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to MDM, try Microsoft Access or another comparable tool in the "Jet Database / Game Chart" category.
The MDM 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 MDM converter.
