CSV to Bar Chart — Free Online Tool

A bar chart is the go-to chart type for comparing discrete values across categories — revenue by region, users by plan, errors by service. This tool lets you generate a bar chart from any CSV file in seconds.

Map your X column (categories) and Y column (values), optionally apply an aggregation like Sum or Average to group repeated category values, and choose a color palette. The chart is interactive: hover for exact values, zoom in, and pan.

Frequently asked questions

Can I group and aggregate values in a bar chart?

Yes. Use the Aggregation selector (Sum, Average, Count, Min, Max) to collapse multiple rows with the same X value into a single bar.

Can I make a horizontal bar chart?

Horizontal orientation is on the roadmap. Currently bars are rendered vertically.

Next step

Charting a CSV export means the data already went stale.

Every refresh is another export, another upload, another chart. Connect the source itself to your AI agent with Sequel and ask for the chart against live data.
