Load your CSV, choose the column to count, set case and trim handling and how many top values to show, then read the frequency table and copy it.
Every distinct value in the chosen column with how many times it occurs, its share of the total as a percentage, a running cumulative percentage and a small bar so you can see the shape of the distribution without building a chart.
Yes. The case-insensitive and trim options fold values like 'Email', 'email' and ' email ' into one bucket, which is essential when counting free-text fields such as channels, tags or survey answers.
You can limit the table to the top N values and the rest are grouped into a single 'other' line with its own count and percentage, so a column with thousands of unique values still gives a readable summary.
