Last updated: 2026-11-02

Features & Capabilities

Open JSON, JSONL and NDJSON files in a full browser tab. Edit source with syntax highlighting, validate and format JSON, inspect a tree or table, apply local schemas, preview JSONata transformations, compare documents and download edited copies. Exact number tokens survive formatting and source edits. JSONL uses indexed records and downloads the complete file with applied edits. Files stay on this device; schema settings persist locally and can be forgotten. No account or browsing access. Ordinary JSON: up to 64 MiB; JSONL: up to 2 GiB and one million records. JSONata uses JavaScript numeric precision and rejects unsafe numeric input. Downloads save copies, not the original file. Optional usage statistics are off by default. Enable them in extension options to send workspace/file open, export and failure counts plus product, browser, version and a random installation identifier to PostHog in the United States. No file contents, filenames, URLs, search terms, edits or error messages are included. All features work with analytics off; disable it at any time.

Is JSON Editor Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

JSON Editor does not require any sensitive permissions.

Risk impact analysis details

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

JSON Editor is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
