Time Domain Data or Correct Data Structure for System Identification Toolbox

Hi,
New to Matlab's system identification toolbox. I have a question regarding the data structure requirement in terms of time domain data.

The system requires that I have input and output data.
Please see attached screenshot...will something like this qualify as a correct time domain data for the system identification toolbox? where first column is time, second column is input and third column is output? I could also create an iddata using data = iddata(y,u,Ts). I want to be sure however that the data I will be importing to the workspace is in the correct format first.
Are there any other data format I can use? My data is in two parts, input and output (20 rows each), both of them sharing the same timestamps.
Any guidance on the appropriate representation of my data will be appreciate!
Thank you!

The signals appear to be regularly sampled, so that should work. The iddata function is an appropriate starting point for time domain data.
