Channels in TDMS File in Excel Misaligned from Time Column

Issue Details

I am using FlexLogger or another National Instruments data acquisition software to generate a TDMS file. When I open this file in Excel, the second tab shows the data, but the channels sampled at slower rate are not properly aligned with the leftmost Time column that shows relative time.


This is a known issue with the TDM Excel Add-In for Microsoft Excel 17.0.0 and older. The column showing relative time will only be correctly aligned with the first channel of data, not all channels. The issue will be addressed in newer releases of the TDM Excel Add-In.

Additional Information

FlexLogger TDMS Viewer can be used as an alternative to TDM Excel Add-In.
