Switching rows and columns for an import file

Question

How can I generate a code for switching rows and columns of a random .txt file? The data inside that file may contain strings, which must be switched too.

I import the data in a table format, but I want to export the same file with just rows and columns interchanged.

A quick way of doing it?

The data can be for example:

Thank you in advance

Answer 1

See below an example where I swap second and third row and I all the columns:

data = {{"a", "b", "c"}, {1, 2, 3}, {4, 5, 6}};

(* Rearrange rows *)
data[[{1, 2, 3}]] = data[[{1, 3, 2}]];

(* Rearrange columns *)    
data[[;; , {1, 2, 3}]] = data[[;; , {3, 1, 2}]]

{{"c", "a", "b"}, {6, 4, 5}, {3, 1, 2}}

(* Export in txt file *)
Export["test.txt", data, "Table"]

Next time please provide a .txt file to work with, not just an image of it.
