Frequently Asked Questions
Keys with dots (like 'database.host') are automatically organized into INI sections. 'database.host' becomes a [database] section with 'host=value'.
Comments are preserved and converted from Java Properties format (# or !) to INI format (#). The content and placement of comments are maintained where possible.
Unicode escapes (like \u0041) in Java Properties are decoded to their actual Unicode characters in the INI output, making the text more readable.
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.
Java Properties line continuations (backslash at end of line) are automatically resolved into single values in the INI output, since INI format doesn't support line continuations.
Properties without dots are placed in a default [General] or [Main] section in the INI file to maintain proper INI format structure.
Special characters in Properties keys are preserved in the INI output, though some may be escaped differently due to format differences between Properties and INI files.
