How to extract text from your TDM file

  1. Click the "Select File" button above, and choose your TDM file.
  2. You’ll see a preview, if available.
  3. Click the "Convert file to..." button to extract text information.

Convert TDM to another file type

To convert TDM metadata files to another format, you need DIAdem or other Data software.

Convert a file to TDM

To convert other file formats to the "Test Measurement Data File" file type, you need software like DIAdem or a similar tool.


About TDM files

.TDM (Technical Data Management) files store test, measurement, and simulation data generated by National Instruments software, primarily DIAdem and LabVIEW. These files are used in engineering to log sensor data, waveforms, and channel configurations.

The format is highly fragmented and proprietary. A major disadvantage is that a .TDM file often only contains the structural metadata (usually formatted as XML), while the actual bulk binary data sits in a separate companion TDX file. You cannot open these files in standard spreadsheet software like Microsoft Excel without installing heavy, specific plugins. Furthermore, natively interacting with them usually requires expensive software licenses.

To make this data usable across different platforms, you should convert .TDM files to CSV or XLSX. This allows data scientists to process the metrics in standard tools, though complex multi-channel metadata hierarchies might be flattened during export.

Because this file format is a closed, proprietary engineering format, it is difficult to open or convert. Often only the original software can properly read or export the data. Standard online converters fail to process it. However, you can use convert.guru. Just drag and drop your file to identify the format, view it, and convert it when possible. Since many .TDM files contain underlying XML or ZIP structures, our analyzer can still inspect the file and extract text, metadata, or channel names.

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.


FAQ

If you want to convert TDM file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use DIAdem or similar software from the "Technical Data Measurement Storage" 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 TDM, try DIAdem or another comparable tool in the "Technical Data Measurement Storage" category.



The TDM 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 TDM converter.
