# # Formula mode

To start using formulas, you need to be in formula mode. Formula mode needs to be switched on at the field level, and most input fields support formula mode.

To toggle from text mode into formula mode, click **formula** on the top-right of the input field. This changes the background color to indicate that you are in formula mode. The type icon on the left will also change to the `fx`

icon.

*Formula mode is displayed with the fx symbol*

When the input field is toggled into formula mode, the string type input field changes icon from String type to `formulas`

type.

In formula mode, the formula editor provides a set of whitelisted formulas available for data transformation/manipulation, and provides additional help on how to use these formulas.

## # Filter formulas displayed by data type

The formula editor will display type-specific formulas for your datapills. Refer to this article for more on the different types of datapills.

When a string type datapill is dropped into an input field in formula mode, the editor shows the list of formulas applicable to strings.

## # Formula hints and syntax

Once a formula is selected, a detailed description of the formula will be provided. This includes an explanation of how to use this formula and examples for how it can be used.

## # Text VS formula mode

In text mode, text, and pills can be mapped into the input fields easily, and they will result in a text that looks exactly like what is formed. On the other hand, text needs to be explicitly formatted in formula mode.

Let's use an example of a recipe that sends an email to new leads in Salesforce. If a new lead called Madison Diaz is created, we wish to send the following email:

```
Hi Madison,
Thanks for joining our mailing list! We're excited to have you!
```

In text mode, the **Message** can simply be formed like this:

*Email in text mode. Example recipe (opens new window)*

In formula mode, text must have proper string syntax:
