# How to use Transformation during import

{% hint style="info" %}
**Prerequisite:** This tutorial assumes you know the basics of the import feature. If this is not the case you can learn the basics in other guides here: [How to use import](/pim3/tutorials/helpful-guides/how-to-use-import.md)\

The tools this tutorial goes through are all found on the data mapping page of import
{% endhint %}

## Transformation

When importing Text or Number [attributes](/pim3/fundamental-concepts/attributes.md) you can choose to do Transformation on the incoming values. This is done by clicking the 'Transform' text to the right of the data mapping.

Whether you click 'Transformation' for a Text [attribute](/pim3/fundamental-concepts/attributes.md) or Number [attribute](/pim3/fundamental-concepts/attributes.md) determines the tranformations that are eligible.

Transformation for Text has the following options:

* All caps
* All non caps
* Capitalize first letter in sentence
* Capitalize first letter in word
* Trim
* Replace
* Regex replace

These are all pretty selfexplanatory and require no other choices to be made, except Replace and Regex replace.

Replace takes an 'Old value' and a 'New value'. In the example above all occurences of 'jacket' will be replaced with 'pillowcase' for the [attribute](/pim3/fundamental-concepts/attributes.md) the Transformation was added to.

Regex replace is similar, however it takes a pattern instead of an 'Old value'. This pattern is in the form of a regular expression and all occurences that fits the pattern will be replaced with the new value.

Transformation for Numbers has the following options:

* Divide
* Minus
* Multiply
* Plus

And they do exactly what they say.

Having chosen your Transformation type simply input the Number for the operation and the operation will be executed on the [attribute](/pim3/fundamental-concepts/attributes.md) that is imported.
