CSV Data Explorer (EDA) Online

This tool profiles a CSV so you can understand it at a glance. For every column it detects the type, counts the values, and reports how many are missing and how many are unique.

Numeric columns get minimum, maximum, mean, median and standard deviation plus a histogram; text columns get their most frequent values. It is a fast first look before deeper analysis.

Type detection marks a column numeric when every non-empty value is a number, boolean when the values are true or false, otherwise text. Empty cells are counted as missing, not as a category.

The distribution is a ten-bin histogram for numbers and a top-values list for text, drawn as simple bars so patterns and outliers stand out without a charting library.

Every conversion happens locally in your browser, so your data is never uploaded, logged or stored on a server. You can use it on confidential exports without a second thought, and it keeps working offline once the page has loaded.

There is no sign-up, no watermark and no row limit: the only ceiling is your device's memory.
