#FAQ
What is a .properties file? ▾
A .properties file is a simple text format used primarily in Java applications for configuration. Each line contains a key-value pair separated by = or :, with # or ! for comments.
How are nested keys handled? ▾
Dot-separated keys like "database.host" are expanded into nested JSON objects: { "database": { "host": "value" } }. This gives you a structured JSON output from flat property keys.
