CSV to Line Chart — Free Online Tool

Line charts are ideal for showing how a value changes over an ordered dimension — time series data, version numbers, experiment iterations. Upload your CSV and pick the column that represents the X axis (e.g., date, month, version) and the Y axis (e.g., revenue, latency, count).

The chart renders with markers at each data point and connecting lines. Hover over any point to see the exact value. Export as PNG for reports or SVG for further customization.

Frequently asked questions

Can I plot multiple lines from one CSV?

Multi-series line charts are on the roadmap. Currently a single Y column is plotted per chart.

Does it support date/time on the X axis?

Yes. Plotly automatically detects ISO date strings and renders a proper time axis with smart tick labels.
