Frequently Asked Questions
INI sections become key prefixes in the Properties file. For example, '[database] host=localhost' becomes 'database.host=localhost' in the Properties output.
Comments are preserved and converted from INI format (# or ;) to Java Properties format (#). The content and relative position of comments are maintained.
Special characters are properly escaped for Java Properties format. Unicode characters may be converted to Unicode escapes (\uXXXX) for compatibility.
Yes. The conversion happens entirely in your browser with no file size limits imposed by the server. Large configuration files are processed efficiently in-memory.
If an INI file has multiple sections with the same name, the keys are merged in the Properties output. Later keys will overwrite earlier ones if they have the same full name.
Keys that appear before any [section] header are treated as global properties and included in the output without any prefix.
Empty lines are preserved where possible, but the overall formatting may change due to differences between INI and Properties file conventions.
