Key Features

1. Flatten Nested JSON

   • Converts deeply nested objects into a single-level list of key-value pairs.

   • Supports dot notation (parent.child.key) and array indexing (array[0]) for precise mapping.

2. Array Handling

   • Processes arrays seamlessly, creating keys that represent the index of each element.

   • Nested arrays and objects are recursively flattened.

3. Base64 Binary Detection

   • Automatically detects string values that are Base64-encoded, flagging them as binary.

   • Useful for safely handling file attachments, images, or encoded payloads.

4. Dynamic and Type-Safe

   • Works with unknown or dynamic JSON structures.

   • Preserves data types for primitives: string, number, boolean, null.

5. Developer-Friendly

   • Lightweight and efficient JavaScript implementation.

   • Provides a clean, reusable pattern for any JSON manipulation scenario.

Input:

{

  "id": 123,

  "owner": {

    "firstName": "John",

    "lastName": "Doe"

  },

  "attachments": [

    { "fileName": "invoice.pdf", "contentBase64": "JVBERi0xLjMK..." }

  ]

}

Output:

[

  { "Key": "id", "Value": 123 },

  { "Key": "owner.firstName", "Value": "John" },

  { "Key": "owner.lastName", "Value": "Doe" },

  { "Key": "attachments[0].fileName", "Value": "invoice.pdf" },

  { "Key": "attachments[0].contentBase64", "Value": "JVBERi0xLjMK...", "IsBinary": true }

]
