Chart Editor
Every chart starts with your data in a familiar spreadsheet interface. Enter or paste your data, pick a chart type, adjust your setting, and watch the live preview update immediately as you work.

Enter data the way you already know
The M Chart editor uses a real spreadsheet interface. Type values directly, paste rows straight from Excel or Google Sheets, and organize larger data sets across multiple sheets on a single chart. No custom markup.
Prefer to work from a file? The fully keyboard-accessible CSV import supports configurable delimiters, and is the recommended way for screen reader users to enter chart data.
See the chart as you build it
The live preview redraws immediately as you edit your data and settings. Change the chart type, swap the theme, or adjust the units and you’ll see exactly what your chart will look like before you publish it. What you see in the editor is what shows up on your site.
