Json Works is a set of static web pages. There is no server that receives your JSON, CSV, tokens or commands — pasting, parsing, converting and exporting all happen in JavaScript on your device.
What is stored, and where
- History — the inputs you paste or open, so you can return to them. Stored in your browser’s IndexedDB for
jsonworks.dev. Up to 30 entries per tool, each up to 20 MB. - Preferences — theme, table options (fit, export settings), panel width and your last JSONPath, kept in
localStorage.
Nothing is synced between devices and nothing is readable by us.
How to delete it
- Open History in any tool and use Clear, or use Clear all saved history in the footer.
- Clear cookies and site data for jsonworks.dev in your browser settings. History is removed with it.
- Private / incognito windows discard everything when closed.
What we do not do
- No accounts or sign-ups.
- No uploads. Your JSON, CSV, tokens and commands are processed locally and never sent to our servers. You can verify this in your browser's network tab.
- No third-party requests from the tools themselves. Fonts are served from this site.
Advertising and cookies
The site may display ads served by Google AdSense and other third-party vendors. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this or other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the internet. Ad vendors never receive the content you paste into a tool.

Analytics
We may collect aggregate, anonymous usage statistics (such as page views, country and browser type) through a standard analytics service to understand which tools are useful. Analytics never include the data you paste into a tool.
Children
The Service is not directed at children under 13 and we do not knowingly collect their personal information.
Changes
We may update this policy; the date below shows the latest revision. Last updated: October 2026.
Be careful with secrets
History is stored unencrypted on your device. If you paste tokens, API keys or customer data on a shared computer, clear the history afterwards. Signing secrets entered in the JWT tool are never saved.
