JSON Blob Formatter

Format minified/escaped JSON blobs into readable, pretty-printed JSON with one command.

Features

• Instantly convert single-line, quoted-and-escaped JSON blobs—like those from logs or APIs—into properly indented, readable JSON.
• Handles files where the JSON payload is surrounded by outer quotes and inner escape sequences.

Usage

Format JSON Blob to Pretty JSON

1. Open a file containing a minified or escaped JSON blob, such as:

   "{\"name\":\"value\",\"list\":[1,2,3]}"
   

2. Press Ctrl+Shift+P (Cmd+Shift+P on Mac) to open the Command Palette.
3. Type and select Format Minified JSON.
4. The document will be replaced with beautiful, readable JSON:

   {
     "name": "value",
     "list": [1, 2, 3]
   }
   

Convert Pretty/Regular JSON back to JSON Blob

1. Open a file containing regular multi-line or pretty-printed JSON.
2. Press Ctrl+Shift+P (Cmd+Shift+P on Mac) to open the Command Palette.
3. Type and select Convert To JSON Blob.
4. The file will be replaced with a single-quoted, escaped JSON blob suitable for embedding/transmission.

Example:

{
  "hello": "world",
  "list": [1, 2, 3]
}

Becomes:

"{\"hello\":\"world\",\"list\":[1,2,3]}"
