To further enhance the business user experience, Contentstack provides prebuilt custom field extensions that let you extend the functionality of your custom fields to serve your unique business needs while providing a native Contentstack look and feel.

Using Contentstack Custom Fields, you can now input a JSON text into an entry field. With the JSON Editor custom field, you can view, edit and format JSON text, code, trees, etc. within your Contentstack entry.

Easy To Interpret: The JSON editor locates errors instantly, eliminating the need to locate errors within the entire code. In addition, it provides multiple view options like code, text, tree to name a few.
Validation made simple: You can validate and check for any necessary fixes in just a few seconds. In addition, because JSON does not have many elements like XML, you can even practice your coding and see the results instantly.
