JSON to INI Converter
Convert JSON data to INI configuration file format.
About the JSON to INI Converter
This tool was designed for developers and system administrators who need to convert modern JSON data into the classic INI configuration format. While JSON is the standard for web APIs, many legacy systems, applications, and tools still rely on the simple, section-based structure of INI files. Our converter seamlessly bridges this gap.
To make this the best tool for the job, we built a smart parser that correctly handles the conversion logic. It transforms top-level and nested JSON objects into INI `[sections]` using dot notation, and correctly formats arrays. The entire process runs securely in your browser, so your sensitive configuration data is never sent to our servers, ensuring your privacy.
How to Use the Tool
- Paste your JSON object into the "Input JSON" editor on the left.
- The "Generated INI" will appear on the right, updating in real-time.
- If your JSON is invalid, a helpful error message will appear.
- Use the buttons to copy the generated INI, download it as a `.ini` file, or clear the editors to start over.
Frequently Asked Questions
What is an INI file?
An INI file is a text-based configuration file format that organizes data into sections (`[section]`), each containing key-value pairs (`key = value`). It's known for its simplicity and human readability and is still used by many applications.
Why would I convert JSON to INI?
You might need to convert JSON to INI when interfacing with a legacy system that requires an INI configuration file, or when generating configs for software that uses this format. For example, you might get a configuration from a modern web API in JSON and need to save it as a `.ini` file for a local application.
How does the tool handle nested JSON objects and arrays?
Our tool follows common conventions. A nested object in JSON is converted into a dot-notated INI section (e.g., `"database": { "test": {} }` becomes `[database.test]`). A key with an array of values becomes a series of keys with `[]`, for example, `"users": ["admin", "guest"]` becomes `users[] = admin` and `users[] = guest`.
Can I convert a JSON array as the top-level element?
No. The INI format does not have a standard way to represent a top-level array. The root of your input must be a JSON object (`{...}`). If you paste a JSON array (`[...]`), the tool will show an error.
Is my data private?
Yes. All conversion from JSON to INI happens entirely in your web browser. Your data is never sent to our servers, so you can safely use this tool with sensitive configuration files.
