Need a fast way to convert your INI data into JSON format? Our INI to JSON Converter is a simple, efficient, and completely free tool that transforms your configuration data in real-time—directly in your browser.

Whether you're upgrading legacy applications, working with APIs, or simply cleaning up old settings, this converter allows you to switch from the traditional .ini format to structured, modern JSON—and back again—instantly.

INI files have long been used to store application settings, especially in older Windows-based environments. But as development has advanced, JSON (JavaScript Object Notation) has become the preferred standard for storing and sharing structured data.

This tool helps you easily modernize your configuration files by converting INI to JSON on the fly. No downloads, no installations, no account needed—just copy, paste, and convert.

• Real-Time Conversion: Paste your INI data and see the JSON output instantly.
• Two-Way Format Support: Convert both INI to JSON and JSON back to INI easily.
• Simple, Clutter-Free Interface: Designed with clarity and ease of use in mind.
• Copy & Export Options: Quickly copy the result or download input/output in a ZIP file.
• 100% Browser-Based: All processing happens locally in your browser. Your data is never sent or stored.

Need to revert JSON data back into INI format? Simply switch to the "JSON ➝ INI" tab, paste your JSON, and get a ready-to-use INI file.

This feature is perfect for developers maintaining compatibility between legacy systems and modern tools.

No file uploads. No tracking. No external servers. All conversions happen right in your browser using JavaScript. This ensures 100% data privacy and ultra-fast performance.

• Developers modernizing old applications
• Cross-platform projects needing consistent config formats
• Web & mobile developers using JSON APIs
• System administrators managing server settings
• Students learning about data serialization

INI Input Example:

[database]
host=localhost
user=admin
password=secure123

[server]
port=3000
mode=production

Converted JSON Output:

{
  "database": {
    "host": "localhost",
    "user": "admin",
    "password": "secure123"
  },
  "server": {
    "port": "3000",
    "mode": "production"
  }
}

While INI files are simple and easy to read, they are limited in structure. JSON offers:

• Nested object support
• Standardized formatting
• Widespread language compatibility
• Built-in parsing in most programming languages
• Ideal format for APIs, databases, and configuration

An INI file is a plain-text configuration file commonly used in Windows applications. It includes sections (in square brackets) and key-value pairs to store settings.

Example:

[settings]
theme=dark
language=en

JSON (JavaScript Object Notation) is a lightweight and readable data format used for storing and exchanging structured information. It’s the standard in modern programming, APIs, databases, and web development.

Example:

{
  "theme": "dark",
  "language": "en"
}

• Ensure correct INI syntax: section headers with [brackets], key-value pairs using =
• INI comments using ; or # are ignored
• Make sure JSON input is valid with proper brackets and quotes
• Use this tool only for properly structured configuration data

Just paste your data and go. This free, browser-based INI ⇄ JSON converter tool gives you everything you need to modernize and manage your configuration files—without installing anything or uploading files. Instant, secure, and reliable.
