Can I convert .CSV to .S2P?

Hi, I have .CSV file and I would like to convert it to .S2P. Can I do that and how. I try to used the notepad and convert it but when I want to read back the file an error such: invalid numeric input. Can anyone help me how to do this.
Thank you in advanced

Hi,
It would be easy to help, if you could post your .csv file.

If your data has frequency unit GHz and data in real imaginary format, with 50 Ohm reference impedance, this is the header line:

# GHZ S RI R 50.00000

If your data has frequeny unit Hz, use HZ instead of GHZ

If your data is in linear magnitude/angle format, use MA instead of RI
If your data is in dB/angle format, use DB instead of RI

Then, the next lines contain frequency and data pairs (real/imag or magnitude/angle) for S11, S21, S12, S22

Example:

# GHZ S DB R 50.00000
