You need to tell more details than “didn’t work”. Did you get error messages, unexpected import data, or? You should provide enough detail so others can reproduce the issue.
I had no problem importing the lines from your post on Windows and on Linux:
I was able to import the points using the SeaDas format without issues . but i couldn’t import the points into the Empirical Bathy tool. When i try import the points, i get this error
What problem are you referring to? There is no universal standard for CSV files. Multiple tools in SNAP use CSV files, and not all accept the same format (likely because some were developed outside of SNAP and later adapted, so are stuck with a format other than SNAP’s, so you have find the relevant documentation or example files to determine the appropriate format.
