JSON

JSON stands for JavaScript Object Notation and is a text format in which programs exchange data. It is structured so that humans can read it and machines can understand it unambiguously — both at once, and that is the reason for its widespread use.

A JSON file consists of pairs of names and values. A user profile might read: name “Anna”, age 34, active yes. Values can be numbers, text, boolean values, lists, or entire objects again — this allows even nested structures to be represented, such as a list of posts, each of which in turn carries an author, date, and reach.

Why it turns up everywhere

Almost every programming interface on the web responds in JSON. Anyone retrieving data from a service — weather data, stock prices, their own usage statistics — usually receives it in this format. It has largely replaced XML because it requires significantly fewer characters and can be read into practically any programming language with a single line.

Language models, too, mostly output structured answers as JSON. When a model is not supposed to deliver flowing text but, say, an assessment with justification and a confidence value, JSON is the usual format — it can be checked by machine, whereas free text cannot.

What it means for users

If a platform offers an export “as a JSON file”, this means: the data does not arrive as a finished table or chart, but in its raw form. This is less convenient to read, but more complete — nothing has been simplified or omitted for the sake of presentation. Spreadsheet programs and analysis tools can read such files; opened in a text editor, you see curly brackets, quotation marks, and colons.

This is precisely where the difference between a dashboard and a data export lies: the dashboard shows what the provider considers important. The JSON file contains what is actually stored.
