Convert Properties to JSON

Convert Properties to JSON transforms .properties config files into structured JSON instantly. The Convert Properties to JSON tool includes live preview, file import, copy, and export.

Paste your input above or import a file below.
No file chosen
Supported file types: .properties, .txt
Total characters: 0

How to Use:

Paste your .properties file content into the Input Properties box. The format should follow standard key=value pairs like:

name=Alice  
[email protected]  
active=true

If you already have a file, you can use Choose File to upload a .properties or .txt file. Once added, Convert Properties to JSON will automatically parse the lines and convert the content into a structured JSON object. The result appears in the JSON Output box and updates live as you type or import.

Click Copy Output to copy the result to your clipboard, or use Export to File to download the JSON as a .json file. You can reset the entire tool at any time with the Clear All button.

What Convert Properties to JSON can do:

This tool takes traditional .properties files common in Java apps, Spring Boot configs, and legacy systems and converts them into clean, usable JSON objects. It handles booleans, numbers, and strings automatically and ignores comments and blank lines. You get live conversion, output flashing, and a character counter so you know exactly what’s changing as you edit or import.

Example:

Input:

name=Alice  
age=30  
active=true

Output:

{
  "name": "Alice",
  "age": 30,
  "active": true
}

Common Use Cases:

Convert Properties to JSON is useful for developers migrating from Java-style configuration files to JSON-based systems. Whether you’re working on microservices, API integration, or simply trying to reformat legacy config data, this tool makes it quick and easy to convert formats on the fly right in your browser.

Useful Tools & Suggestions:

If you’re starting with structured data, Convert Form Data to JSON can offer a more browser-friendly route before tackling .properties files. Then, once everything’s in JSON, Convert JSON to YAML is a handy way to shift formats depending on your target environment.
