Select line in 2D array from contest

I need some help regarding looking in data log-file.

Every minute in the log file is there a timestamp that I need to filter out and post the first one for user.

I use “Read From Spreadsheet File VI” to fill in the data and delete some columns with data I not need to show In grafh.

I have attached the vi and a test log-file

Hi,

after using ReadFromSpreadsheetFile the way you do you will not find any tmestamps in your data as they get converted to zero just year and hour (as they don't fit the given format code).

You need to read in the file as text (or as array of strings) to be able to filter your timestamps!
