Access number of columns (or data groups) in a csv?

[andrewmarston]

Anyone know how to access the total number of columns (or groups of data) in a csv? Ae provides easy access to the number of rows in the data of a csv using the following:

thisComp.layer("CSV Filename.csv")("Data")("Number of Rows");

However, I can't figure out how to pull the number of columns. It's for a template I'm creating for myself to make line charts easily, and column number changes from csv to csv.

In this example, the desired output of the expression would be 11.

Nevermind, I finally found it using numProperties:

thisComp.layer("CSV Filename.csv")("Data")("Outline").numProperties;
