Lua Requires Chilkat v11.0.0+

Sort JSON Object by Member Key Name

See more JSON Examples

Demonstrates how to sort the members of a JSON object by the key name. Lua

local chilkat = require("chilkat")

local json = chilkat.JsonObject.new()

json:update_string("xyz", "1234")
json:update_string("abc.xyz", "1234")
json:update_string("abc.def", "1234")
json:update_string("abc.aaa", "1234")
json:update_string("ghi", "1234")
json:update_string("nmo", "1234")

json.emit_compact = false
print(json:emit())

-- This is our initial JSON:

-- {
--   "xyz": "1234",
--   "abc": {
--     "xyz": "1234",
--     "def": "1234",
--     "aaa": "1234"
--   },
--   "ghi": "1234",
--   "nmo": "1234"
-- }

-- Sort the top-level JSON object by key.
local ascending = true
local caseSensitive = true
json:sort(ascending, caseSensitive)

-- Look at the sorted JSON..
print(json:emit())

-- {
--   "abc": {
--     "xyz": "1234",
--     "def": "1234",
--     "aaa": "1234"
--   },
--   "ghi": "1234",
--   "nmo": "1234",
--   "xyz": "1234"
-- }

-- Now sort the members of the "abc" object..
local jsonAbc = chilkat.JsonObject.new()
json:object_of2("abc", jsonAbc)

jsonAbc:sort(ascending, caseSensitive)

-- Now look at the JSON with the members under "abc" also sorted..
print(json:emit())

-- {
--   "abc": {
--     "aaa": "1234",
--     "def": "1234",
--     "xyz": "1234"
--   },
--   "ghi": "1234",
--   "nmo": "1234",
--   "xyz": "1234"
-- }
