# File Column Mapping

Council staff can map the format of files output from the back office directly into OneVu so it understands the content of the file and make additional data items in the file available to use in notifications:

It is then possible to use these pieces of data within notifications - read more here:

{% content-ref url="../notification-content/notification-placeholders" %}
[notification-placeholders](../notification-content/notification-placeholders)
{% endcontent-ref %}
