JSON Viewer FAQ
Are large numbers preserved?
Tree rendering, search and downloads preserve original JSON numbers. JSONPath evaluation requires numbers that JavaScript can safely represent and rejects unsafe values instead of rounding them.
Does it pretty-print my JSON?
Yes. It formats and renders your JSON as an interactive, collapsible tree so you can explore large structures quickly.
Can I query with JSONPath?
Yes. Type an expression like $.store.book[*].author into the JSONPath box and only the matching values are rendered.
Is my data uploaded?
No. Parsing and rendering happen entirely in your browser.
