[Urgent] How to Import txt file into CST MWS

Dear Members
I have a S-parameter txt file containing two columns. How can I import this txt file into CST-MWS so that I may plot the S-parameters inside the electromagnetic simulator.
Awaiting replies,
Regards

Two columns?
You should have three columns: frequency and complex reflection factor (real/imag or dB/phase)
If you only have frequency and magnitude, you can't use the data for simulation.
If your file has these 3 columns, it can be easily used as Touchstone file by adding the corresponding header line:

Show your file.

@volker:
File attached.
This file is exported originally from CST MWs. I need to modify something and see its effect again by importing into CST.
S-para_4.5-8_GHz.txt

Your file has no complex data, just magnitude. It is not possible to use this in simulation.
If you want to have it in a plot, to compare to other results, see here:

Thank you for the clarification,
But can you explain the procedure if I do have snp file..How can I import that?
