Cant read time stamp from LVM file into array or export to Excel

[ASAT]

Good Afternoon!

Im having issues getting the time stamps back from an LVM file and into an excel file.

Ulitmately, I have a series of LVM files with 6 channels of data and the correspodning time stamps.

When I read the files back into an array, the channel values are parsed, but the time stamp is no where to be found. The channel data then successfully exports to an excel sheet (minus the times stamps).

How can I extract the time stamps with the channel data and get them into an excel sheet?

NOTE: I do know you can open the LVM file directly into excel, however, the information is not "parsable".

I appreciate the toughts. I've enclosed my experimental code as well as the data set I am trying to extract. I've also included a destination excel sheet.

forsome reason, the code would not attach to my previous emial, so, here it is. The .LVM file is zipped, for some reason, this forum doesnt recognize the lvm extension.

Hi ASAT,

Is there a reason that you are not simply using the Write to Measurement File.vi to write your signal data to the excel sheet? This is an easy way to bring in your signal data to an excel sheet (see attached file). You can also view the code within that Express VI to see how this is achieved.

Hi Murari208,

Have you tried using the Read from Measurement File Express VI?

Also here is a tutorial that shows how to write and read from LVMs which you can find useful:
