JSON Viewer & Editor

Open a JSON file, see it as a tree or as text, search it, edit it, and save it back to the original. No sign-in.


■ View

- Tree: expand and collapse to see the structure, with item counts and paths ($.items[3].name).
- Text: the file as it is, with line numbers. Very long lines are folded.
- Big files: open files up to 50 MB. Over 5 MB, you can view and search.
- Broken JSON: see the line, the column and the reason.
- XML files open as a tree of elements and attributes (view only).


■ Search and copy

- Search keys and values and jump to each match. Nothing is filtered out, so you see what's around it.
- Copy a value, a key, a path or a whole node. Copy all the text too.


■ Edit and save

- Change values, rename keys, add, duplicate or delete items, or edit the text directly.
- Undo.
- Saving changes only what you edited. Indentation, key order and number formats (1.0, 1e3, long integers) stay as they were.
- Before saving, the app backs up the original. After saving, it reads the file back to check. If that fails, it restores the original or keeps a copy in Recovery files.
- If the app closes suddenly, you can continue from the last automatic save.
- Save pasted JSON as a new file.


■ PDF

Save or share the text as a PDF with line numbers.
