Text → parse → Tree / Table

Tree and Table views are regenerated from valid JSON when you refresh. Invalid text stays visible so you can fix it without losing your source.

Good to know

Frequently asked questions

Can I edit the Tree or Table directly?

The first editor version treats Text as the source of truth. Use the Tree and Table views to explore and search, then make edits in Text and refresh the views.

What does Collapse all affect?

It closes every expandable object and array in the Tree view. Expand all opens them again so you can scan the full structure.

What does search look through?

Search can match every row, JSON path, value text, or JSON type. Matching rows are highlighted in Tree and filtered in Table.
