I want to know how to convert a file .pcap to a plain text, i've tried using:
tcpdump -r input.pcap > output.txt
and it works, but the text inside the file isn't the same data in the pcap file when I open the pcap in wireshark
I want to export to text without using wireshark interface, I want to do it through the terminal in Linux.

One quick example, just to get you started, is:

tcpdump dissects packets differently from Wireshark, so
As Chris Maynard noted, you need to use a program that dissects packets the same way Wireshark does; TShark uses the same dissector code that Wireshark does, so it's the program to use.
