# Adding Columns

You can add an arbitrary number of additional columns to any Arcwise connected data tab. These columns are defined using spreadsheet formulas that are identical to the formulas in Google Sheets. To filter data navigate to the Arcwise connected data interface [Arcwise Connected Data](/using-arcwise-in-sheets/arcwise-connected-data.md).

{% hint style="info" %}
Arcwise provides AI suggestions for column formulas. If you give your column a meaningful name (EG: month\_number) then Arcwise will typically provide a suggestion that computes the value you need.
{% endhint %}

Arcwise supports most formulas. To see a complete list see: [Supported Formulas](/using-arcwise-in-sheets/supported-formulas.md)

1\) Click on the formula button (**Σ**) in the **Fields** section.

3\) Arcwise AI will give a suggestion in the blue box. If this suggestion appears correct you can accept it by clicking the **Formula** box and hitting Tab. If the suggestion is not correct you can enter your own formula to define the new column.

4\) After adding the column you will see a new field with your column name in green. You can edit or delete this column later. Click the green **Update query** button in the bottom left corner to add your new column to the data.
