Linked record (Link to another record)

array of record IDs (strings)

A linked record field allows you to represent the relationships between related records by creating links between them. This is particularly helpful when you have multiple tables of related items or concepts—for example, if you have a table of contacts and a table of companies, you can use a linked record field to link each contact to the company that they work for.

Long text (With or without rich text formatting enabled)


A long text field is great when you need to keep notes or multiple lines of text in each record. You can enter new lines into a long text field, and even @mention a collaborator inside the text. If you need more styling options, you can enable rich text for the field.



array of numbers, strings, booleans, or objects

A lookup field allows you to look up a specific field in a linked record.

Legacy default values in fields 

Legacy field values

Single line text, number, currency, and percent fields in bases created before January 31, 2024, offer the option to toggle on/off "Apply default value for all actions." 

Any fields displaying "Apply default value for all actions" rely on a legacy default value used inconsistently. You can toggle "Upgrade to consistent default value behavior" on to address the previous inconsistencies. 

The following scenarios did not use the default value for legacy fields but will after enabling "Upgrade to consistent default value behavior:" 

  • Using the Airtable automation action: Create record without specifying a field value.

  • Using public APIs to create a record without specifying a field value.

  • Submitting a form without a legacy field. 

  • Importing a CSV without specifying field mapping for the related field.
