• Because everything is computed client-side, Java Properties to JSON is safe to use with sensitive data such as API keys, tokens or private logs.

How to use

Using Java Properties to JSON takes three steps:

1. Paste your data into the input box (or load the example).
2. Configure the options to match your target format or scenario.
3. Copy, download or inspect the output — it updates live as you type.
