Instead of use of shortcode, you can get the post content, format them the way you want and display them later.
You can use get_the_content function; which will just retrieve post content in a variable.
$raw_input = get_the_content();
/*process your content here and store the result in variable
eg.*/
$raw_input = str_replace("No", "Yes", $raw_input);
print $raw_input;
This will print the processed content and you can just comment out the_content()
function in your single.php
.
