Frequently Asked Questions
Can the viewer handle very large JSON files?
Yes, but very large files (over 1MB) may take a moment to render. The collapsible tree helps navigate large structures efficiently.
Does it show array indices?
Yes. Array elements are displayed with their numeric index starting from 0.
