Create professional charts from spreadsheet data, customize the design, and download high-quality files without signing in.
SemiOffice Chart Maker is a browser-based chart creation workspace for office staff, students, analysts, small businesses and anyone who needs a clear visual from spreadsheet data. Paste rows copied from Excel or Google Sheets, upload CSV, XLS or XLSX data, choose a chart type, adjust the design and export the finished visualization. The editor is built around the chart itself, so you can move from raw numbers to a presentation-ready graphic without creating an account or installing desktop software.
Create column and horizontal bar charts, line and area charts, pie and doughnut charts, stacked column charts, 100% stacked charts, stacked horizontal bars and stacked area charts. These formats cover everyday reporting needs such as monthly sales, department expenses, survey responses, targets, project completion and category comparisons.
For more specialized work, use waterfall, funnel, radar, treemap, KPI gauge, scatter, bubble, histogram, box plot and heatmap views. A combination chart can place bars and a line in one visual when two measures need to be compared together. Smart Chart can also suggest a useful starting format based on the data you provide.
Export PNG at standard, high or ultra resolution, or choose JPG, WebP, SVG and PDF. Transparent-background export is available for PNG, WebP, SVG and copied chart images, making it easier to place a chart on slides, reports, websites or branded documents without a white box around it.
Use the chart maker for sales reports, expense summaries, KPI dashboards, survey results, marketing performance, project status updates, financial presentations and classroom assignments. Built-in sample datasets provide a fast starting point when you want to explore the editor before adding your own data.
