I have multiple text files. I want to read a particlar line from those text files and combine them together in a separate text file as an output. If I want to read line number 69 from each files and write in a separate text file (or csv) as an output, How can I do that? I have attached three text files and I am expecting output like I have attached.

For each text file, you can read the contents line by line (link). Reading a specific line number could be done by using a normal counter variable. Once you have the contents of the line, save it to an array. You can then write the contents to a csv file using writematrix (link).

Hope this helps :).
