# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://manual-2.karamba3d.com/3-in-depth-component-reference/3.7-export/3.8.2-json-bson-export-and-import.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
