Data dashboard: turn Excel & CSV into interactive charts
Load an Excel or CSV file and build an interactive, filterable dashboard by drag-and-drop. Columns are detected automatically and the dashboard appears in seconds – entirely in your browser, no upload.
How the dashboard works
Load a file, pick value and category columns, done. SmashDash suggests suitable charts; you arrange them freely, resize tiles and choose a colour scheme in real time.
- Seven chart types: bar, line, area, pie, doughnut, horizontal bars and Sankey.
- Live filters on any column – every chart updates instantly.
- Drag-and-drop builder with resizable tiles and reordering.
- Merge several files into one dataset (e.g. for time series).
Export without a server
Export your dashboard as a static HTML page to share, as an interactive HTML file with live filters, or as an offline version with embedded libraries – all without a server and without uploading.
Who is the dashboard for?
The data dashboard suits students, teachers, freelancers and teams who want to turn an Excel or CSV file into a clear analysis fast – without spreadsheet formulas or specialist software. Because everything runs in the browser, you can safely analyse confidential numbers from surveys, sales or projects. German number formats such as 1.234,56 are detected correctly and automatically.
