Frequently Asked Questions

How do nested objects map?

Top-level keys become sections, nested paths flatten with dots. Deep trees need restructuring — INI is flat by design.

Arrays in INI?

Repeated keys or indexed suffixes per target parser — INI has no arrays. Confirm the consuming app's convention first.

Round-trip back?

Sections restore to nested objects where dot paths exist. Comments and ordering don't survive — keep JSON masters.

Is JSON data uploaded?

No — conversion runs locally in your browser. Data never leaves your device.
