# 3.8.2 Json / Bson Export and Import

For passing data over the internet the Json and Bson format have become increasingly popular. Karamba3D offers a pair of import/export components to and fro Json and Bson.

Fig. 3.8.2.1. shows an example of a Json conversion which results in a large text. Use the input-plug 'Path' at the **'Export Model to Json'**-component to save the file to disk. In case th file-name has the extension '.bson' the binary, shorter and faster Bson format will be chosen. The same applies to the **'Import Model from Json'**-component.

The model is exported in such a way that references are preserved: if e.g. two elements refer to the same cross section the cross section will be exported only once.
