FAQ

Does it validate a schema?
No. It only checks that JSON.parse succeeds, then reprints it.
Comments in JSON?
Standard JSON has no comments. Strip them or the parser will complain.
Do you store what I type?
Browser tools stay in this tab. Refreshing the page clears the form. Nothing is saved to a Pulse account.
Is this free?
Yes. Pulse stays free because of advertising. Ads may appear when you copy, download, or run the main action.
