JSON Deserializer

A powerful VSCode/Cursor extension that recursively deserializes JSON strings into readable, formatted objects.

Features

• 🔄 Recursive Deserialization: Automatically finds and deserializes all JSON strings nested within your JSON structure
• 📝 Multiline String Formatting: Converts strings with newlines into readable, formatted multiline strings
• ⚡ One-Click Operation: Right-click and select "Deserialize JSON" - works on entire files or selections
• 🎨 Pretty Formatting: Outputs beautifully formatted JSON with 2-space indentation
• 🔁 Deep Nesting Support: Handles multiple levels of nested JSON strings

Usage

1. Open a file containing a JSON string (like test.json)
2. Either:
   • Select the JSON text you want to deserialize, OR
   • Leave no selection to deserialize the entire file
3. Right-click and select "Deserialize JSON"
4. The JSON string will be converted to properly formatted JSON in place

Example

Before (nested JSON strings):

{
  "function": {
    "name": "write_file",
    "arguments": "{\"path\":\"/app/test.js\",\"content\":\"function test() {\\n  console.log('hello');\\n}\"}"
  }
}

After (deserialized and formatted):

{
  "function": {
    "name": "write_file",
    "arguments": {
      "path": "/app/test.js",
      "content": "function test() {
        console.log('hello');
      }"
    }
  }
}

Notice how:

• The arguments string was parsed into an actual object
• The content string with \n escapes became a readable multiline string
