How to make a line graph

  1. Paste your data from Excel or Google Sheets, or open a CSV or Excel file.
  2. Add a title, and choose colors, size and number format.
  3. Download it as PNG, SVG or PowerPoint.

Good to know

  • Each column of numbers becomes a line, named from the first row.
  • Empty cells leave a gap in the line instead of a drop to zero.
  • Turn off "Start the value axis at 0" to zoom in on small changes; choose Area for a filled version.
  • Open a PNG saved here to keep editing it: the PNG keeps the data and settings inside.

Frequently asked questions

How do I compare two years?

Put the months in the first column and one column per year, such as "2025" and "2026": each year becomes its own line.

Is my data uploaded?

No. The chart is made in your browser and your numbers never leave your device.
