# Specifying Teltonika AVL parameters in raw data export

## Question

How to specify certain Teltonika AVL parameters when exporting raw data?

## Answer

When exporting a Raw Data spreadsheet for a Teltonika tracker, you can specify either a single AVL parameter, a list of parameters, or a range of AVL parameters in the Raw Data settings window.

Let's break down all possible variations of specifying an AVL in the Raw Data export settings.

First, select an AVL input you need from the list:

![](/files/3ce7a6b59908d86785ab7d29818ebf8706e392b6)

### 1. A range

You can specify a range of numbers for a given AVL ID parameter in the following format:

e.g. `37-453`

![](/files/c5e91b53a467fca5fb47ef14d78cd7253e2fa4f1)

In this case, all AVLs between `avl_io_37` "¦ and "¦ `avl_io_453` will be included in the Raw Data spreadsheet:

![](/files/a75d23f1d8cd116266c0ce018c24a8696f1f0126)

### 2. A set of AVL input numbers

To specify a set of numbers for AVL inputs, use the following format: `37,38,45,599`

![](/files/524eabce6e8180966d829eefe079f6a4165d037d)

This results in the spreadsheet containing `avl_io_37`, `avl_io_38`, `avl_io_45`, and `avl_io_599` columns:

![](/files/25830b5ce07275e91c0efd859f37d751ca6ce89b)

### 3. A single number

In this case, just one column for `avl_io_37` will be included in the Raw Data spreadsheet export:

![](/files/962413eb52223e8eef35f3341149347eaf3489fd)

The same format rules apply to all other numbered parameters and inputs available in the Raw Data export window.
