How do I convert a .csv to a .dat using MATLAB (SWAN Modeling)

I have an excel sheet (.csv) with four columns, (PNEZ) with input XYZ data points from bathymetric survey for a site. I need to convert that file (recommended using MATLAB) to a .dat file to run a SWAN wave analysis. If anyone could guide me towards a tutorial or a similar code I could use to do so it would be extremely helpful. If you need further information please let me know.

Many programs use .dat as an extension for their own format so a .dat file could be anything. It could contain text with a particular formatting or some binary data depending on the program.

If you don't have more details about your specific program .dat format, there's not much we can do. For all we know, the only thing you may have to do is just rename the file from .csv to .dat.

Google returned thousands of results for "SWAN wave analysis". However, I didn't find the format of SWAN's dat-file.

Hi,

Try reading the data from the .csv file into a table in MATLAB and then write that table into a .dat file.
