Forge JSON Editor Overview

Edit, compare, and manage JSON safely — with version history, diff tools, and predictable syncing.

What you can do

• Edit JSON with instant feedback
• Compare changes side-by-side
• Track every version automatically
• Sync across tabs and devices
• Detect and fix invalid JSON

Key ideas

• One editor at a time Only one tab can edit a document. Others are read-only.

• Auto-save in the background Local edits are instant. Saving happens automatically.

• Versioned history Every change creates a version you can review or restore.

• Two-panel system Use left and right panels to edit, compare, or preview.

Common workflows

Edit and save

1. Open a document

3. Wait for Saved status in the status bar

For a guided path through editing, comparing, and running transforms, see Edit, Compare, and Transform.

Compare changes

1. Open the same document in both panels
2. Load different versions
3. Enable compare mode — see differences highlighted

Fix invalid JSON

1. Edit freely (even if invalid)
2. Errors appear inline
3. Use repair tools to fix before saving

Sync across tabs

1. Edit in one tab
2. Other tabs receive updates after a short delay
3. If a newer version exists → Update available
