Extract text from TDM files
To convert your TDM file to another format, you need NI DIAdem or other Data software.
To convert other file formats to the "XML Measurement Header" file type, you need software like NI DIAdem or a similar tool.
A .tdm file is the XML-based header component of the National Instruments TDM data model. It functions as a roadmap, containing all the descriptive metadata - such as channel names, unit descriptions, sensor properties, and test conditions - while the actual measurement values (waveforms, bulk numbers) are stored in a separate, companion tdx file.
Users often encounter a major issue: .tdm files are text-readable XML, but they do not contain the "data" you are looking for. Opening a .tdm file in a text editor like Notepad displays raw XML code, not a spreadsheet. Furthermore, if you separate the .tdm from its tdx partner, the file becomes useless because the link to the binary data is broken. To analyze this data without proprietary engineering software like NI DIAdem or LabVIEW, the best workflow is to convert the paired files into universally accessible formats.
Recommended Conversion Targets:
Convert.Guru analyzes your TDM file, detects the exact format, and lets you read the text inside.
Users also converted TDMS, TMD, TMDX, TDMS_INDEX, CY and CMI files.
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 TDM converter.
