You can create a **Custom column** based on your requirement. Name your field and choose your desired input format. The field can hold one of the following formats:

* **String**: You can add alphabets, numbers or alphanumerical inputs. Any number that is added will not have a numerical value (cannot be used for definite measure)
* **Number**: You can add numerical values to your field.
* **Boolean**: You can add Boolean Operators. Ex: '1' representing 'True' and '0' representing 'False'.
* **Date & Time**: You can add date, day and time inputs.

[Here is an example of how to create a custom column for meta fields](https://docs.dataexport.io/kb/reports/custom-fields/calculated-fields/add-metafields-to-your-report)

We have categorized custom columns into two types:

{% content-ref url="custom-fields/calculated-fields" %}
[calculated-fields](https://docs.dataexport.io/kb/reports/custom-fields/calculated-fields)
{% endcontent-ref %}

{% content-ref url="custom-fields/static-field" %}
[static-field](https://docs.dataexport.io/kb/reports/custom-fields/static-field)
{% endcontent-ref %}
