How do I get the latest observation date for a given data feed using the Excel Add-In?

For data feeds in time-series format, you can set the number of observations using the Limit option. You can find the Limit option by going to the Quandl tab on Excel, clicking Get Data and then following the prompts until you reach the Filter tab where the Limit option is located. Indicate 1 in the Limit option to download the latest observation.
