INI to JSON Converter
Convert INI configuration files to JSON format. Parse legacy INI files with automatic type detection for booleans and numbers. Perfect for modernizing configs, API integration, and data processing workflows.
Conversion Options
Recommended Settings
For Modern Apps
- •Enable type coercion for smart boolean/number conversion
- •Use 2-space indent for web applications
- •Sort keys for easier diff comparison
For Safety
- •Disable type coercion to preserve all values as strings
- •Test with small samples before bulk conversion
- •Verify output structure matches expectations
Pro Tips
- •Use minified output for production config files to reduce size
- •Enable sort keys when comparing configs across versions
- •All conversion happens client-side for complete privacy

Most users enable type coercion with 2-space indentation
When to Use This Tool
Migrate legacy INI configuration files to modern JSON format for use in web applications, Node.js services, or REST APIs. JSON is the standard format for most modern applications and provides better structure for complex configurations with nested objects and arrays.
Recommended: Modernization
Convert INI configuration data to JSON for REST API requests or responses. Most web APIs expect JSON format, so converting INI configs allows you to integrate legacy systems with modern API-driven architectures seamlessly.
Recommended: Integration
Parse legacy INI configuration files for data analysis, reporting, or automated processing. JSON format makes it easier to manipulate data programmatically in JavaScript, Python, or other languages with robust JSON support.
Recommended: Analytics

Frequently Asked Questions
What is INI format?
INI (Initialization) is a simple configuration file format consisting of sections, keys, and values. It's commonly used in Windows applications and legacy systems. Format example: [section] key=value. INI files are human-readable but limited in data structure complexity compared to JSON.
How does type coercion work?
With type coercion enabled, the tool automatically converts values: 'true', 'yes', 'on' → boolean true; 'false', 'no', 'off' → boolean false; numeric strings → numbers (e.g., '123' → 123). Disable type coercion to keep all values as strings for safety.
What happens to INI sections?
INI sections (e.g., [database]) become top-level JSON objects. Keys within sections become properties of those objects. Keys outside any section are placed at the root level. Example: [db] host=localhost → {"db": {"host": "localhost"}}
Are comments preserved?
No, comments (lines starting with ; or #) are automatically stripped during parsing as JSON doesn't support comments. If you need to preserve comment information, consider adding them as description fields in your INI structure.
Is my data safe?
Absolutely! All conversion happens entirely in your browser using client-side JavaScript. No data is ever sent to any server, ensuring complete privacy and security for your configuration files.
