I have a large JSON file. It is not easy to work on all file at a time. I want to fold some content so that I can work on a section of JSON file.


  obj: {+}, // folded section
        // unfolded section

Is it possible to fold JSON structure in Vim?


Yes, it is possible. A minimal setup would be:

:set filetype=json
:syntax on
:set foldmethod=syntax

  • FWIW: This isn't enabling folding for me. "E490: No fold found". – spazm Nov 3 '20 at 20:40

    @spazm: So you can probably ask a new question here, describe what OS you're using, what exact editor, what version, all the steps you're doing, all the info that could be helpful. – grodzik Nov 5 '20 at 12:53
