— before you buy.

Both dashboards below were built with Kolumna from one and the same Excel file — sales data by region. Nothing is retouched: what you open is exactly the HTML file the tool produces.

Source One Excel file
Result One HTML file
Time A few minutes
Example I · Light mode

Sales by region

The default theme — soft, light, ready for email and intranets.

KPI cards with targets and change arrows, bar and donut charts, a trend line, a comparison view and a filterable table — all generated automatically from the columns in the file.

Do try it yourself: click Edit layout in the dashboard, drag the sections around and resize them. The layout is saved locally in your browser — and that is exactly how it works for your recipients too.

The example dashboards are in Swedish — Kolumna produces dashboards in Swedish or English, matching your data.

Example II · Dark mode

Same data, dark theme

One click in the generator — same content, different suit.

Kolumna ships with two themes: light and dark. You choose in the final step, and colours, charts and tables follow along. Print is always light, whatever the theme — so the paper version holds up.
