FAQ（5）
Does the tree modify my JSON?
No. It parses and renders an expandable tree; Copy returns pretty JSON without changing the data model beyond parse/serialize norms.
How does it handle large files?
Very large trees can slow or freeze the tab. Trim input or use JSON Formatter / CLI tools for huge documents.
Is JSON uploaded?
Never. Parsing stays on your device. LocalKit processes this in your browser on www.908885.com—input is not uploaded to our servers for computation.
What if JSON is invalid?
You will see a parse error—fix trailing commas, quotes, or truncated pastes. Validate with JSON Formatter if needed.
How do I start collapsed?
Uncheck Expand all (or equivalent) and re-run so nodes start collapsed for easier navigation. LocalKit processes this in your browser on www.908885.com—input is not uploaded to our servers for computation.
