All nodes in Runchat store data in a specific format that allows the node to perform calculations. The data format type is indicated by the colour of node input and output parameters and edges. When you connect parameters of different types, Runchat will try to convert or “cast” the data from the output type to the input type. Runchat supports casting between all common data types. Data that has been cast is indicated by a gradient coloured edge.

​
Files and URLs

Runchat will always try to upload images and files to our servers and return a url string that represents the file content. This allows workflow file sizes to remain small and latency to be kept to a minimum.

​
Objects

Object (specifically JSON objects) are strings with a special notation used to describe properties of things. Objects are made up of strings called keys , each with a value that can be any data type you like - including another object. Objects are always written in the same format: 
{ 
"key": "value"
}
The start and end with curly braces {}, and keys and values are always separated by a :. Because a lot of third party APIs (including language models and services like youtube) return data in object format, runchat needs to work with them. Runchat defaults to the object input for object types, where you can easily add keys and values including creating nested objects.

​
Arrays

An array is a list of other data types. All runchat parameter data is stored as an array. If a parameter has more than one thing in this array, runchat will display a pagination UI on the node to allow you to step through inputs and outputs.
