Questions
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.
Can I convert Spring Boot application.properties to JSON?
Yes, paste your Spring Boot properties file and the tool will expand dot-notation keys into a nested JSON structure that mirrors the configuration hierarchy.
Does the converter handle Unicode escape sequences?
Java properties files can contain Unicode escapes like \u00E9. The converter parses these sequences and includes the actual characters in the JSON output.
