About this product

A two-panel JSON editor that runs in your browser: text, tree and table modes, compare, JSON Schema validation, JSONPath/JMESPath queries, repair and CSV export. New: files over 100 MB open in huge file mode, up to 4 GB. The file stays on disk, a worker checks it in one streaming pass, and the tree reads rows as you scroll. Open any part up to 50 MB in the second panel to edit it. Free, no account, files stay on your device.
