# Byte to human readable

## Description

This operation converts a size in bytes into a more human-friendly format, such as kilobytes (KB), megabytes (MB), gigabytes (GB), and so on. This operation is especially useful for interpreting file sizes or data storage values.

***

## Data types

These are the input/output expected data types for this operation:

### Input data

`String` - Sizes in bytes to be transformed. They must be strings that represent integer numbers.

### Output data

`String` - Resulting human-readable strings.

***

## Example

Suppose you want to convert a series of events that represent **sizes in bytes** into **human-readable strings**:

1. In your Pipeline, open the required [Action](/pipelines/actions.md) configuration and select the input **Field**.
2. In the **Operation** field, choose **Byte to Human Readable**.
3. Give your **Output field** a name and click **Save**. The byte sizes in your input field will be transformed into human-readable strings. For example:

```
Input data - "134367"

Output data - "131.22 KiB"
```

You can try out operations with specific values using the **Input** field above the operation. You can enter the value in the example above and check the result in the **Output** field.
