We've all faced the problem of lack of information in our app. All interfaces seem lifeless and empty. Debugging with no data is also not simple.
I think that each of us has at least once in their lives created a bunch of files with JSON data, but they were just one object propagated without unique fields. JSON Generator was created in order to help with this. It provides an opportunity generate any data and in any quantity. Edit template, click "Generate" and you're done.
If you have found a bug, you have a suggestion for improving the application or just want to thank me, click on "Feedback".
JSON Generator has a convenient syntax. You can specify JavaScript object for template that you see in the left box. It will be cloned in infinite depth. Fields can have any name and value, but it must be valid JavaScript. Values, which are strings, may contain one or more template tags. When you click "Generate" the data source object to be copied several times and the place of tags will be inserted random values.
You can copy the generated JSON to clipboard by clicking "Copy to clipboard". Also you can download generated file by clicking "Download" button. Generated JSON size appears at the top right of the field with the generated data.
You can choose indentation for the generated JSON from the drop-down list. It can has values of "Compact", 2, 3 and 4.
JSON Generator remembers your last template in localStorage. If you want to reset it, click "Reset" button to reset template and UI.
