Tips for INI

Sections use [section]. Keys are key = value with spaces around =.
Values are strings by default; booleans/numbers may be coerced when converting to JSON.
Comments start with ; or #. Duplicate keys may overwrite previous values.
Complex nesting isn’t native to INI; JSON → INI may flatten structures.
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.
