For example, there is a view.
The view has been executed and has results.
How can I alter these results. For example, I need to change the letter "a" to the letter "b" in result of some field.
How can I do it ?
I'm looking into hook_views_pre_render and hook_views_post_render, but can't understand how to get results and how to change them.
Could you share your experience how to do it ? Or could you share useful links ?
