Privacy and data handling
Input and output are processed by the current browser tab. The site has no content upload API and does not write your content to an account or cloud storage.
Formats and limitations
Uses the browser native JSON.parse, so comments, trailing commas, single quotes, and JSON5 syntax are not accepted. Very large JSON is limited by device memory.
Frequently asked questions
Does sorting keys change the data?
