When working with a data set, you may be looking to pull out a specific subset of it — like the first item of a list, or the last 5 rows of a table. Coda offers *First, Last, Nth, and Slice* formulas to better provide the structure you need for your data set.

Our example uses a simple list of numbers: [1, 3, 5, 7, 11, 13]. These formulas allow specific items from the list to be filtered based on their position.

How to use formulas

First: Returns the first item from a list or table.

=List(1,3,5,7,11,13).First() 

Output: 1


Last: Returns the last item from a list or table.

=List(1,3,5,7,11,13).Last() 

Output: 13


Nth: Returns the Nth item from a list from the number provided.

=List(1,3,5,7,11,13).Nth(5)

Output: 11


Slice: Returns the part of the provided text or list based on the numerical position.

=List(1,3,5,7,11,13).Slice(2,4)

Output: [3, 5, 7]

Ways to use Slice

With Slice in particular, there are a few different varieties you can try:

  • Give me the first 3:  

=List(1,3,5,7,11,13).Slice(1,3)

1,3,5

  • Or, give me the last 2:

=List(1,3,5,7,11,13).Slice(-2)

11,13

  • And even, pull out specific rows:

I'm working with the Urgent Open Tasks table in our Product Launch Hub, and I wanted to get the last 3 rows of this table which are sorted by their End Date:


Using Slice, I'm able to build it into the core project table: 

=[Urgent Open Tasks !!].Sort(True, End).Slice(-3)
