“I will do it”
He said he would do it
He said he will do it
My question is when can I use these two versions, 1 and 2. In which situations is it correct to use version 1 or version 2?
In other words when do I need to switch tenses?

I add some context and summarise what @FumbleFingers said.
Edit
If the party is on 7 Jan, and someone said on 4 Jan "I will do it" in response to a request to book a table by 5 Jan, both examples can be used on 5 Jan if there is still time for the task. Backshifting is normal but not mandatory.
Only example 1 is possible on 6 Jan because the chance to book the table has passed.
