FIN 579 Vibe Coding Exercise

CSV Column Checker

I built the app below for a class assignment and posted it here for my instructor and classmates. Upload a CSV file and the app lists the column names, tells you whether each column is numerical and has missing values, and averages every numerical column with no missing values. You can also pick any numerical column to see its average and standard deviation.

Choose a CSV file or drag and drop it here

Your file is read in your browser. It is never uploaded or stored.

Step 1

Variables

Step 2

Type and missing values

Column	Type	Missing values

A cell counts as missing when it is blank or reads NA, N/A, NaN, null, or None. A column is numerical when every value that isn't missing is a number.

Step 3

Averages

Column	Average

Step 4
