Quickly beautify json data. For privacy and security all data remains in your browser and is not sent to any server.
This JSON beautifier was created with data privacy in mind. The JSON data submitted to the site stays local to your browser. The data you provide will never go to a third party or be used for advertising purposes. It is not even sent to our hosting provider. We didn't trust any of the existing sites out there to not collect potentially sensitive data. All code delivered by this site can easily be inspected to know it's not being sent anywhere for collection. There is no third party Javascript on this site.
There are no ads displayed on the site. The popular site jsonprettyprint.net is rather annoying with ads and places the button to format JSON right in between two ads leading to accidental clicks on ads. PrintJSON.com is 100% ad free.
HTTPS is always used for secure communication to the site. In addition to being aggressive with ads jsonprettyprint.net doesn't require use of HTTPS and your data is submitted unencrypted over the internet. This can lead to data snooping and sensitive data being leaked.
This basic JSON formatter is nothing fancy but it does the job. The standard JSON.parse() is used by the JSON viewer to quickly parse the data and find errors. Detailed error messages will be provided if JSON parsing fails. The JSON.stringify() is used for formatting the JSON displayed in the text area.
