Which JSON Operations Does JSON Editor Online Support?

JSON Editor Online is a browser-based tool for viewing, editing, formatting, repairing, comparing, querying, transforming, validating, and sharing JSON data. It suits developers who need to inspect or clean up JSON from APIs and databases, and it covers most everyday JSON tasks in one place. The site describes the tool as "completely free," and a separate pricing page exists, so check that page if you need details on paid plans.

Core editing and viewing

The editor offers three ways to work with the same document:

• Text mode — a plain-text editor for raw JSON.
• Tree mode — a collapsible node view for navigating nested structures.
• Table mode — a tabular view for array-style data.

Switching between modes keeps the undo/redo history, so you can move to another view to inspect something without losing your edit history. In text mode, "Expand All" and "Collapse All" buttons help you navigate large, deeply nested documents: collapse everything, then expand only the nodes you need, or use the search box to jump to a part of the document.

Formatting and beautifying

The formatter and beautifier reformat JSON into a consistent, readable layout. This is the typical first step when you paste in minified or messy JSON from an API response and want to read or debug it.

Comparing and repairing

• Compare lets you diff two JSON documents to see what changed between them.
• Repair helps fix malformed JSON documents.

These are useful when you receive a broken payload or need to confirm that two versions of a config or API response match.

Querying and transforming

The query and transform features let you extract or reshape parts of a JSON document rather than editing it by hand. This fits tasks such as pulling a subset of fields out of a large response or restructuring data before using it elsewhere.

Validation

JSON Schema validation checks a document against a schema, so you can confirm the data matches an expected structure before relying on it.

Conversion and large files

• JSON to CSV and CSV to JSON converters move data between the two formats.
• The tool can process large JSON files, which matters when a document is too big to comfortably handle by hand.

Loading, saving, and sharing

You can load, save, and share JSON online through the editor, and an offline JSON editor is also available for working without a connection.

Quick reference

If your task is one of the operations above, the tool likely covers it. If you need pricing or account details, consult the site's pricing page rather than assuming the free tier covers everything.
