# 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 inputis an identifier, and not a string literal any more.
