Hope you find it somewhat useful. Remember, The save is in your lua folder.
next line?
thx

edit:
also if i wanna overwrite a line with a variable, what do i do cause when i try file:write("\n") then it just overwrite everything, is there anything that allows me to skip line without overwriting it?

"w+" deletes everything in a file before attempting to write to it. These are more useful, I hope.

path = saves -- The directory where you will place the save.
file_save = {0 = [path/text document.txt]}
function save()
file:write(file_save[0],"w+")
end
Here's a tutorial for y'all.
SaveTableToFile
Yasday has written
io.write(player(id,"health").."\n\n\n\n\n")
You don't need to concatenate when writing to a file.
Instead you should pass it as different parameters to save yourself from doing needless concatenations.

Ohh, it's very simple, you just have to rewrite the whole file instead of the part you want to edit
It's not possible to write to a part of a file (that's why we got databases, but not in lua)
and how long to write 1000 lines from array using w mode in a loop?
At this point, seeing as how you are using a very inefficient serialization method to begin with, I really doubt that the rumtime complexity of IO is something that you have to worry about.
