# Messages View Data Byte Format

Six format buttons are located in the [bottom toolbar](/vspy-3-documentation/3.9.15/vehicle-spy-main-menus/main-menu-spy-networks/messages-view/messages-view-bottom-toolbar.md) of [Messages view](/vspy-3-documentation/3.9.15/vehicle-spy-main-menus/main-menu-spy-networks/messages-view.md) (Figure 1).These buttons allow for quick, one-click formatting of the DataBytes, Arb ID/Header, and J1939 PGN [columns](/vspy-3-documentation/3.9.15/vehicle-spy-main-menus/main-menu-spy-networks/messages-view/messages-view-column-headers.md).\
The six buttons pictured below (from left to right) are: Hexadecimal, Decimal, ASCII, Binary, Unicode Big Endian, and Unicode Little Endian.

![Figure 1: Change the data byte format with a single click!](https://2396693198-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FlRJv2XDCMeZSU0VbeZlG%2Fuploads%2Fgit-blob-0dc92d82ebbc5e521287f84c6d8ceff01aa75b79%2Fspydbytefromat.gif?alt=media)

The DataBytes column supports all six formats, but other columns have special cases as follows:

* Arb ID/Header - will use the hex format if ASCII or either unicode format is selected.
* J1939 PGN - remains decimal even if hex format is selected.
* J1939 PGN (Hex) - displays hex OR decimal depending upon the format selection.

This format selection does NOT affect the contents of saved buffers. Saved buffers always use the hexadecimal format.

## 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://docs.intrepidcs.com/vspy-3-documentation/3.9.15/vehicle-spy-main-menus/main-menu-spy-networks/messages-view/messages-view-bottom-toolbar/messages-view-data-byte-format.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.
