# Build Text Collection from Field

Takes a collection of records as `input` and the name of a field and builds a text collection containing the values of the specified `field`.

If you specify `unique` as `true`, the collection will only contain unique values, removing duplicates.

For example, if you specify `input` as a collection of Leads and `field` as `Email`, this will generate a collection containing a list of email addresses. Depending on the value for `unique`, duplicate email addresses will be removed.
