This is a Neovim-only plugin containing a function to return a path to access the value under the cursor by using treesitter. It may help you understand how to access even deeply nested values in JSON files.

A "JSON path" is a jq-like expression, such as . for root, .[0] for the first array item, .name for the property "name" of an object.

Using lua:

-- in after/ftplugin/json.lua

if vim.fn.exists("+winbar") == 1 then
  vim.opt_local.winbar = "%{%v:lua.require'jsonpath'.get()%}"
end

-- send json path to clipboard
vim.keymap.set("n", "y<C-p>", function()
  vim.fn.setreg("+", require("jsonpath").get())
end, { desc = "copy json path", buffer = true })

Using vim:
