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.
