Code Formatter & Minifier

A simple VS Code extension to minify, beautify, mitify, sort JSON, sort JSON arrays, sort JSON arrays by key, and provide UUID generation utilities.

Features

JavaScript

• Right-click inside a JavaScript (.js) file:
  • “Minify this file” -> Minify using terser.
  • “Beautify this file” -> Beautify using js-beautify.
  • “Mitify this file” -> Runs minify + beautify in sequence (for normalized, clean code).
• Note: The “Mitify” command is available only for JavaScript files.

JSON / JSONC

• Right-click inside a JSON (.json) or JSONC (.jsonc) file:

  • “Minify this file” -> Compact JSON into a single line.
  • “Beautify this file” -> Format JSON with indentation (using tabs).
  • “Sort this file” -> Sort JSON keys recursively in alphabetical order.
  • “Sort List” -> Sort all arrays recursively by their JSON stringified values.
  • “Sort List by Key” -> Prompt for a key name and sort JSON arrays of objects by that key.

• Note: .jsonc files are automatically parsed as .json (comments are stripped).

  The output file will not contain comments, as they are removed during parsing.

JSONL

• Right-click inside a JSON Lines (.jsonl) file:
  • “Minify this file” -> Compress each JSON object on every line into a single compact line.
  • “Beautify this file” -> Format each JSON object on every line with indentation and line breaks.
  • “Sort this file” -> Sort JSON keys recursively within each JSON object.
  • “Sort List” -> Sort JSON objects and arrays line by line recursively.
  • “Sort List by Key” -> Prompt for a key name and sort JSON objects by that key line by line.
• Each line is parsed and processed independently without merging across lines.
• Note: Internally, JSONL parsing uses jsonparse and a custom circular-safe stringifier.

Sorting by Key

• Use the “Sort List by Key” command to sort JSON or JSONL arrays of objects by a specific key. You will be prompted to enter the key name in an input box. Works for both entire files and selected text.

UUID Generator

• Right-click to use Generate UUID.
• Inserts a freshly generated UUID at every selected cursor position in the active editor.

Usage

1. Open a .js, .json, .jsonc, or .jsonl file in VS Code.
2. Right-click inside the editor.
3. Choose the desired operation from the context menu.
4. You can also select text and run:
   • “Minify current selection”
   • “Beautify current selection”
   • “Mitify current selection”
   • “Sort current selection”
   • “Sort lists (selection)”
   • “Sort lists by keys (selection)”

Notes

• JavaScript minification uses terser.
• JavaScript beautification uses js-beautify.
• JSON parsing uses jsonc-parser.
• JSONL parsing uses jsonparse.
• JSON operations remove comments on save.

Extra

• All edit operations automatically save the document (unless untitled).
• Both LF (\n) and CRLF (\r\n) line endings are supported.
• Works with multiple selections.
• Displays success, warning, and error messages consistently.
