Hello

You could define a function which converts your number to a string,
replaces the points with a comma, and maps this to all the numbers of
your table:

mod := Map[StringReplace[ToString[ #], "." -> ","] &, #, {2}] &;

You can test this with:

data = {{1.3, 2.3}, {3.2, 4.3}};
ExportString [mod[data], "TSV"]  (*or*)
Export["test.txt", mod[data], "TSV"]
