CSV Statistics

For each column, the tool calculates total count, unique values, and empty cell count. For numeric columns, it also computes minimum, maximum, mean (average), median, and sum values.

A column is treated as numeric if the majority of its non-empty values can be parsed as numbers. Mixed columns with some text values will still show numeric stats based on the parseable values.

The tool processes CSV data entirely in your browser memory. It works well for typical datasets up to tens of thousands of rows. Very large files may take a moment to analyze.

Yes! All processing happens entirely in your browser. Your CSV data is never sent to any server. No data is collected, stored, or transmitted.

Standard comma-separated values with optional quoted fields. The first row is treated as column headers. Both Windows and Unix line endings are handled automatically.
