Tips for .properties

Separators: =, :, or whitespace (space/tab). Whitespace may be followed by optional = or :.
Escapes: use \:, \=, \#, \!, and \ to include those literally in keys/values. Unicode supported via \uXXXX.
Backslashes: escape as \\. Example Windows path: C:\\Users\\Alice.
Line continuation: end a line with a single backslash \ to continue on the next line. Joined with one space.
JSON → .properties flattens nested objects with dot keys (e.g., user.name=Bob).
Tip: Use Reset to clear one side, or Reset all to clear both panels; use Pretty JSON to format JSON output.
Tip: Press Ctrl/Cmd + Enter in a panel to convert that side instantly.
