Can comments be used in JSON? - Stack Overflow

Hey Suneelek,

JSON is typically used for data only, so if you want to include a comment in your JSON, you should treat it as part of the data. One approach is to add a designated data element, such as “_comment”, that contains the comment text. Applications that use the JSON data can then choose to ignore this “_comment” element.

However, it’s generally better to include comments in the processes that generate or receive the JSON, as they should already have knowledge of the JSON structure. If you decide to include a comment in your JSON, here’s an example of how you might structure it:

   "_comment": "comment text goes here...",
   "glossary": {
      "title": "example glossary",
      "GlossDiv": {
         "title": "S",
         "GlossList": {
            "GlossEntry": {
               "ID": "SGML",
               "SortAs": "SGML",
               "GlossTerm": "Standard Generalized Markup Language",
               "Acronym": "SGML",
               "Abbrev": "ISO 8879:1986",
               "GlossDef": {
                  "para": "A meta-markup language, used to create markup languages such as DocBook.",
                  "GlossSeeAlso": ["GML", "XML"]
               "GlossSee": "markup"

Remember, including comments in JSON is not a standard practice, and it’s generally better to use comments in the code or documentation associated with the JSON data.

I hope this answer works for you, please let me know if need any further explaination.

Hello Suneelak,

Including comments in JSON is not recommended for production use because JSON is designed to be a lightweight data-interchange format. Comments can add unnecessary complexity and make the JSON harder to parse. Instead, comments should be used in the surrounding code or documentation.
