Pick the chart that matches the question you are answering. Use a bar chart to compare values across distinct categories, like revenue by month or votes by option. Use a line chart for a trend over an ordered sequence such as a time series, or an area chart when you want the same trend with the region beneath the line filled to emphasize volume. Choose a pie chart to show how each row contributes to a whole, since it draws a percentage label on every slice. Reach for a scatter plot when you want to plot two numeric columns against each other to spot correlation or clustering. Bar, line, and area charts need one category column and one number column, a pie needs a single value column, and a scatter needs both axes numeric. Paste your data and switch types to see which reads best.

The tool decides whether a column is numeric by sampling the first ten data rows and checking that every sampled value is a real number. If any of those rows contains stray text, the column is treated as categories and can only be used for the X axis, not as a Y value, pie value, or scatter axis. The usual culprits are thousands separators like "12,000", currency symbols such as "$45", percent signs, or placeholders like "N/A" and blank cells sitting near the top of the file. Strip those out so each value in the column is a plain number, keep the formatting consistent down the whole column, and reload. The data preview shows how many columns were recognized as numeric, so you can confirm the fix before charting. Clean the column and the numeric chart options reappear.

Keep the structure simple: one header row of column names at the very top, one record per line below it, and values that stay consistent within each column. The first row becomes your selectable columns, so give every column a clear name and avoid merged or stacked headers. The parser handles quoted fields that contain commas, so a value like "Smith, Jane" wrapped in quotes stays in one cell. Make number columns plain numbers without currency symbols, percent signs, or thousands separators so they register as numeric and unlock every chart type. Besides comma-separated values you can also upload tab-separated .tsv files and plain .txt exports. Avoid totally empty rows and trailing summary lines, which can confuse the layout. Load the built-in sample to see a well-formed example, then paste your own data and chart it in seconds.

The charts are drawn as static images using the browser's HTML5 Canvas API rather than an interactive, hoverable widget, which is why the result exports cleanly to a single PNG. You still get full control before you render: switch between bar, line, area, pie, and scatter, swap which columns map to each axis, add a title and axis labels, toggle the gridlines and legend, and choose from six color schemes including default, pastel, vivid, earth, monochrome, and neon. Pie charts label each slice with its percentage of the total. Because the image is generated on your device, there is no chart library pulled from a CDN and nothing is uploaded, so the tool keeps working even on a flaky connection. When the chart looks right, click Download PNG to drop it straight into a slide deck, document, or README.

Yes. Both Excel and Google Sheets export to CSV, which is the universal format this tool reads. In Excel choose File then Save As and pick "CSV (Comma delimited)"; in Google Sheets use File, Download, then "Comma-separated values (.csv)". You can also copy a range of cells straight from the spreadsheet and paste it into the input box, since copied cells arrive as tab-separated text that the parser accepts alongside .tsv and .txt uploads. Make sure your sheet has a single header row and that number columns hold plain numbers, not currency-formatted or text cells, so they are detected as numeric. The tool samples the first ten rows to preselect sensible X and Y columns, so you usually see a chart the moment your data loads. Paste your spreadsheet export and download the chart as a PNG.
