Unfortunately, Airtable’s API always treats its currency fields like that, so you would need to somehow reformat your currency field as a text string that looks like currency.

One quick fix (although incomplete) would be to just type the $ sign before the field within your automation, which would show you the dollar sign — but that still wouldn’t show you the comma or decimal point.

A complete fix would be to create a formula field that returns the currency string you’re looking for as text. I believe that @kuovonne’s app “Ready-Made Formulas” should be able to help you create that formula:

Another complete fix would be to use an external automation tool like Zapier or Make.com, which would allow you to apply currency formatting to your number before sending the message to Slack.
