JsonEdit

JsonEdit shows a JSON file as a table: you change a value, add a row or a column, without writing any JSON. The unchanged parts of the file are copied as they are.

JSON file open in JsonEdit, shown as a table of records with its tabs.

List shown as number / value, with the tabs and the breadcrumb above it.

Three table layouts

An object is shown as key / value, a list as number / value, a list of objects as records with one column per field. Each object or list at the root has its own tab. A breadcrumb shows where you are.

JsonEdit settings with the backup copy option.

Automatic saving

The file is saved 0.7 s after the last change. A .bak copy is made at the first change. If another program changes the file, JsonEdit reloads it.

Raw text of a JSON file with line numbers.

Raw text and unreadable files

The { } button shows the whole file as text, with line numbers. A malformed file opens directly as raw text, with the faulty line highlighted, so it can be fixed.

How to use

Open a file: "Open a file…" button, drag and drop onto the window, or "Open with".
Double-click a cell to edit it; press Enter on an object or a list to go into it.
Right-click a row or a header: insert, duplicate, move, copy, paste, delete.
Ctrl+F searches the whole file. Changes are saved without any action on your part.

Verify a file

Compute the SHA-256 checksum of the downloaded file and compare it with the one in the table. If they differ, the file was modified or not downloaded correctly.

Windows: certutil -hashfile <fichier> SHA256
Linux: sha256sum <fichier>
