CSV files is a text format. CSV stands for Comma Separated Values.

An Excel file (XLSX) is far more than just a string of texts, separated by commas. It has information about fonts, colors, and other things like borders and how big a cell is.

It is logical that when you save a file as CSV, you will lose everything the CSV does not support. There is no other way around it, but is almost always good enough.

See if the created CSV file can be imported in your Weka program, I bet it can.

  • CSV can have different layouts. For example: "a","b", "a";"b",a,b and even a {tab} b. see if weka has support for different layouts and if not, export as a different kind of CSV from excel. – LPChip Sep 2 at 10:44
