Issue Details

I am using NI software (like FlexLogger, DAQExpress, NI-DAQmx API in LabVIEW, etc.) to log data in a TDMS file format. How do I view the TDMS files?

Solution

There are a few options for viewing TDMS files using NI software.
  • TDMS File Viewer VI: This function is installed with the LabVIEW and allows you to view TDMS data in the TMDS File Viewer Dialog Box
    • View the TDMS Write Triggered Data VI example to see how the TDMS File Viewer works, available the LabVIEW Example Finder: labview\examples\File IO\TDMS\Standard Read and Write
  • TDM Excel Add-In for Microsoft Excel: This software add-in allows importing TDM and TDMS data into a Microsoft Excel spreadsheet, much like you would import CSV or XLSX data.
  • NI FlexLogger TDMS Viewer: This software is included with the FlexLogger license and installs with NI FlexLogger. 
  • DIAdem: DIAdem is specifically designed around TDMS files and allows you to view and visualize TDMS data.
If you are working with software products that are not designed by NI follow, the options in the article Reading and Writing to a TDMS File Using Third Party Software for additional solutions.
