# Field Type Conversions

### What are field conversions?

**[Fields](/docs/about-fields#/)** have the flexibility to be converted from one **[type](/docs/field-types#/)** to another. For example, if you have a Short Text field that you believe would serve users better as a Paragraph Text field, allowing them to provide more detailed information.

### How can I change a field's type?

To perform field conversions, simply click on the ellipses button located to the right of the field and choose the option "Change Field Type":

An editor will be opened for you to select the new field type.

**Notes:**

* Changing the field type for default fields in Payments and Accounts/User Roles is not possible. To learn more, see **[this article here](/docs/field-types#/)**.
* As of 2024-01-15, conversions between compatible field types will be processed by our support team if the number of records exceeds a size threshold. **Incompatible** field conversions are **not** affected by this update.
* For conversions between **compatible** field types, we will be doing a check on the table size and record count before proceeding with the conversion. If the conversion exceeds our threshold, users will receive a notification in the Builder that they will need to **[submit a ticket](https://www.knack.com/contact-support/)** to our support team to complete the field conversion.

### Incompatible Field Types

Certain field types may not be compatible. If you happen to select a field type that is incompatible, a message will appear to inform you of this.

In order to save your changes, you will need to acknowledge and select "I understand".

**Notes** :

* For\*\* \*\* incompatible field types (such as a Yes/No field -> Formula field), these conversions are allowed, with no size threshold. **All data in the field will be deleted, 100% of the time.**
* With incompatible field type conversions, the field key will be retained, meaning that any tasks, formulas, rules, API calls, etc. that depend on the field key will remain intact.
* Changing a field type to an incompatible field type will **not** cause any cascading operations of updating equations, tasks, records, etc.
