You can use the Trim trailing whitespace feature to ensure that any extra spaces at the end of a text field’s value are not saved to Airtable. This is extremely useful to avoid confusion later on in automated workflows where the data needs to be matched exactly. Some user will copy/paste values which can introduce extra, unwanted whitespace.
