# Data Data objects in Midio are essentially a superset of JSON, meaning they support the following data types: * string * number * boolean * null * lists * objects

The above object can be viewed in text mode by clicking the **\** button in the top right corner:

As you can see in the above **object text view**, it is not quite JSON. The object fields (value1, value2, value3, list1 and object1), are **identifiers,** and not **string literals,** as JSON would expect. Since the Midio object notation is a JSON superset, it is perfectly ok to change these to string literals, if you want. To the midio runtime, it makes no difference, and when converting to a JSON string using [Json Parse](/midio-docs/built-in-nodes/core-std.md#json), any identifier will be converted to a string literal anyway.

## Data inputs Data objects can also accept inputs, by specifying an identifier where the data object normally expects a value. You can also convert a value to an input by clicking the **->|** icon that appears when hovering a value in the object editor.

The input that then appears on the left hand side of the data object can then be connected to any other value, either from a function or another data object.

In the **text editor** the above object looks like this:

Notice that `input`is an identifier,
and not a string literal any more.
