You could add a specific class (foo in this example) based on the condition process: false and do the formatting in your css:

<div class="col-sm-4 text-right p_left0" [ngClass]={'foo': !data.process}>{{data.data}}</div>

EDIT:

First of all, take the time to look at the NgClass documentation.

The general syntax is this: [ngClass]="{'classToAdd': condition }"

When condition is truthy Angular will add classToAdd, when condition is falsy will remove the class. So in your case you have some options:

[ngClass]="{'down': data.process === 'down'}" // Add down class when process === 'down', remove it otherwise
[ngClass]="{'up': data.process === 'up'}" // Add up class when process === 'up', remove it otherwise
[ngClass]="{'down': data.process === 'down', 'up': data.process === 'up'}" // Do both
