Ah - I do see what you mean. We will adjust the site so that a "submit" button appears whenever the text is edited so that the text editing is not interrupted. Thank you for the feedback.
This is a great site to use if you are working with JSON data. You can upload a JSON file or paste an API feed URL and it will immediately convert the JSON into CSV. This is useful if you want to quickly sort, filter or chart the data without using any code.
