How do I make a graph in Excel from my data?

Upload your data to Sehnna and describe the chart you want. You get an .xlsx with the source data, a summary tab and a formatted chart, ready to open in Excel.

Which chart types are supported?

Column, bar, line, area, pie, donut, stacked and combo charts with a secondary axis, plus simple multi-chart dashboards.

Can I change the chart after downloading it?

Yes. It is a native Excel chart bound to the sheet data, so you can edit it in Excel or Google Sheets as usual.

Can I get the chart as an image?

Yes. You can export the chart tab as a PDF or image for slides and reports.

Do I need to shape my data first?

No. Sehnna handles the grouping and aggregation, and keeps it on a separate summary tab so your raw input stays clean.

Charts & dashboards

Excel graph maker

Describe the chart you need and get a formatted Excel workbook back — clean source data, a summary tab that does the aggregation, and a native chart with proper axis titles.

Describe the chart, get the workbook

Excel's chart wizard assumes your data is already shaped the way a chart needs it. Usually it is not. Sehnna reshapes the data, builds the series, and puts the chart on its own tab with axis titles, number formats and a legend that makes sense.

Charts you can create

Column and bar charts for comparisons between categories.
Line charts for trends over time, with monthly or weekly buckets.
Pie and donut charts for share of total.
Combo charts with a secondary axis, for revenue against margin.
Stacked charts for composition across periods.
Small dashboards with several charts and KPI tiles on one tab.

How the graph maker works

Upload a spreadsheet or paste your figures, then say what the chart should show. The data stays on its own input tab, the aggregation lives in a summary tab, and the chart sits on a dashboard tab — the same separation an analyst would use.

Step by step

Upload a file, or describe the data you want charted.
Say what the chart should compare and over which period.
Preview the chart and the underlying summary in the browser.
Refine with prompts like 'group by quarter' or 'add a trend line'.
Download the .xlsx, or export the chart as an image or PDF.

Picking the right chart

Comparing categories — use a bar chart, sorted largest to smallest.
Showing a trend — use a line chart with time on the horizontal axis.
Showing composition — use a stacked column instead of several pies.
Two different units — use a combo chart with a secondary axis.
