What file formats does this CSV viewer support?

It supports CSV, TSV, and pipe-delimited files. You can also paste tab-separated or comma-separated data directly. The delimiter is auto-detected.

Is there a file size limit?

The tool runs entirely in your browser so there is no server upload limit. Practically it handles files up to several hundred thousand rows depending on your device.

What statistics are calculated?

For numeric columns: count, mean, median, mode, min, max, standard deviation, variance, sum, range, Q1, Q3, IQR, skewness, and null count. For text columns: count, unique values, most frequent value, longest/shortest values, and average length.

Can I export my filtered data?

Yes. You can export your data (including any active filters) as CSV or JSON, or copy it to your clipboard.
