Stacker tables give you the option to change field names and types within the app.

Only some field type conversions can happen without losing data. For example, you can convert a string field to a long text field with no loss of data. Converting a number to a long text will clear the data in the field.

## Deleting fields

1. Go to **Manage fields and data**
2. Hover over the field you want to delete
3. Click downward arrow
4. Click delete button
