How It Works

See how Next JSON effortlessly decodes multiple levels of encoded JSON strings with just one click. No more manual decoding

Nested JSON Example

Decode a JSON string containing escaped quotes and nested objects.

Input
{
  "user": "{\"name\":\"John\",\"age\":30}",
  "status": "active"
}
Output
{
  "user": {
    "name": "John",
    "age": 30
  },
  "status": "active"
}

Flat Multiple Level Encoding JSON

Flat deeply nested JSON strings with multiple levels of encoding.

Input
{
  "level1": "{\"level2\": \"{\\\"key\\\": \\\"value\\\"}\"}"
}
Output
{
  "level1": {
    "level2": {
      "key": "value"
    }
  }
}

Nested Array in JSON

Process arrays containing multiple encoded JSON strings.

Input
{
  "items": [
    "{\"id\":1,\"value\":\"first\"}",
    "{\"id\":2,\"value\":\"second\"}"
  ]
}
Output
{
  "items": [
    {
      "id": 1,
      "value": "first"
    },
    {
      "id": 2,
      "value": "second"
    }
  ]
}

Frequently Asked Questions

Why build this site?

When i'm formatting the json data i got in the log file, if found it's hard to decode the nested json part, so i build this site to save my time, if it can also help others at the same time, that would be even better.

Does this site store my data in the cloud?

No, this site does not store or share your data in the cloud. Your data remains private and is kept locally on your broswer.

Why do I need to decode nested JSON strings?

Nested JSON strings often occur when JSON data is serialized multiple times, such as when storing JSON in databases or passing it through multiple systems. Decoding is necessary to access and work with the actual data structure rather than dealing with escaped string representations.

How does this JSON decoder handle multiple levels of encoding?

This tool automatically detects and recursively decodes JSON strings at any depth of nesting. It can handle scenarios where JSON has been encoded multiple times, carefully preserving the data structure while removing escape characters and converting string representations back into proper JSON objects.

Can this tool handle arrays of encoded JSON strings?

Yes, the decoder can process arrays containing multiple encoded JSON strings. It will iterate through array elements and decode any JSON strings it finds, maintaining the array structure while properly parsing each encoded element.

This site lacks some useful features that I need. Can you add them?

Yes, we welcome all suggestions! Please feel free to share your feedback using the link below.
