Does it work on both numeric and text columns?

Yes — numeric columns get min, max and mean; all columns get a distinct value count, which is useful for text columns too.

What does "distinct count" tell me?

How many unique values appear in that column, useful for spotting whether a column is mostly unique (like an ID) or mostly repeated (like a category).

Can this replace opening the data in a spreadsheet for a first look?

For a quick sanity check before deeper analysis, yes — it gives you the same overview a spreadsheet's summary functions would, without opening one.

Does CSV Statistics upload my files to a server?

No. CSV Statistics runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

Before doing any real analysis on a dataset, it helps to know its basic shape: the range of values in each column, the average, how many distinct values appear — the kind of sanity check that catches obvious data problems early. This tool computes min, max, mean and distinct counts for every column in a CSV automatically, giving you that overview in one pass instead of calculating it column by column yourself.
