I wonder what you mean by plotting a matrix of data. Other than that, if
your file is stored in text format (and it is composed of numbers only) as
"sample.txt", try

b = ToExpression /@ Import["sample.txt", "Table"]

and if you want to output to a file "sample2.txt", use

Export["sample2.txt", b, "Table"]
