Case Converter UI

A Visual Studio Code extension that converts text between different case formats with an simple interface.

Features

Convert strings, multiple lines, or JSON keys between 9 different case formats:

• camelCase - myVariableName
• snake_case - my_variable_name
• PascalCase - MyVariableName
• SCREAMING_SNAKE_CASE - MY_VARIABLE_NAME
• kebab-case - my-variable-name
• Title Case - My Variable Name
• Sentence case - My variable name
• dot.case - my.variable.name
• path/case - my/variable/name

🎯 Three Ways to Open

1. Status Bar Button: Click the "🔄 Case Converter" button at the bottom-right of VS Code
2. Command Palette: Press Ctrl+Shift+P (or Cmd+Shift+P on Mac) and type "Case Converter"
3. Automatic: The extension activates on VS Code startup

💡 How It Works

Single String Conversion

Convert any text string to your desired case format:

Input:

hello_world

Output (camelCase):

helloWorld

Multi-line String Conversion

Each line is converted independently:

Input:

first_name
last_name
email_address

Output (camelCase):

firstName
lastName
emailAddress

JSON Object Key Conversion

Convert all JSON keys while preserving values:

Input:

{
  "name": "Ajit",
  "email_address": "test@example.com",
  "temporary_address":"hyderabad, India",
  "permanent_address": "Maharashtra, India",
  "user_settings": {
    "theme_color": "light",
    "font_size": 14
  }
}

Output (camelCase):

{
  "name": "Ajit",
  "emailAddress": "test@example.com",
  "temporaryAddress":"hyderabad, India",
  "permanentAddress": "Maharashtra, India",
  "userSettings": {
    "themeColor": "light",
    "fontSize": 14
  }
}

Note: Only the keys are converted; all values (strings, numbers, booleans, nested objects) remain unchanged.

⚠️ Error Handling

If you enter invalid JSON (e.g., missing brackets or quotes), the extension will display a warning:

⚠️ Invalid JSON format. Please check your input.

The error message automatically disappears after 5 seconds.

Usage

1. Click the 🔄 Case Converter button in the status bar (bottom-right corner)
2. Enter your text in the Input box:
   • Single string (e.g., user_name)
   • Multiple lines (each line on a new line)
   • Valid JSON object
3. Select the desired case format from the dropdown menu
4. Click the Convert button
5. The converted result appears in the Output box

Requirements

• Visual Studio Code version 1.107.0 or higher
